After marrying Chad, Raia suddenly feels like she may be in heat. However, she was planning a date...


Raia looked in the mirror as she was applying some seductive lipstick. "This can be the first time Mark and I'll date after marrying Chad, who suggested me to seduce Mark," she said. Raia kept smiling as she looked at pin-up images of her favorite brother she would get to see. "I know he's much younger than me, but still attractive," she thought. As much as Raia admires men, having a history like Mark's has been very difficult to live to tell the tale after surviving a long, traumatizing war. "He didn't have to save Lillian from years of imprisonment, but she was framed back then," she thought as her heart skipped a beat. It was really disturbing to think that Mark risked dying multiple times in order to serve his family. "He's often regarded as the strongest veteran of them all," she said, now in a more seductive tone. Despite some of his flaws, like post-traumatic stress disorder, albeit sometimes known as shell shock, Raia has already known that Mark never reached perfection, nor will he.

"He's seen himself as an imperfect man, but I will love him for who he is," she thought. Mark, who was at his house, felt a growing sense of happiness as his favorite cheetah, Chelsea, presented a handmade painting of her father, who was him. "What do you think? Did it turn out well, Dad," she asked. The heartwarming painting wasn't sexually explicit, but it was fortunately an accurate representation of him, both traits of which Mark liked. "You've done well. I'm glad you've been pursuing art careers," he said. Chelsea blushed from her dad's compliment. "Thank you. You have been my top priority for all of my life," she said with a bow. She stepped out of the room as Mark continued analyzing this portrait. "Anatomically speaking, my girl has done well," he said. He remembered when the original Chelsea's favorite passion was art; for this clone permanently aged in her early-20s, Mark and art were indisputably her two favorite things.

Despite her lack of spots, Mark grew to love the spotless cheetah. One important reason was the fact both Chelseas were his only daughters, something Mark was honestly fine with, as the vast majority of his kids are sons. Regarding his wife Ginger, she did birth Geno, but his half-siblings have had different mothers. Belle, "Finn", Marcy/Milca... "I've had one heck of a life as a dad," Mark thought as he smiled at Chelsea's artwork. It was strange to think about his heroic deeds in the past, but that was not including cheating on his wife. "For the most part, I've been in a semi-open relationship. The act itself can't be justified," he thought. The door bell rang for him as he stored the work his favorite cheetah made. Raia was currently at the door, excited to date Mark once again. "I'm pleased to see you, my friend," she said. Mark blushed as the two hugged; his head was snuggling her cleavage, due to a minor height difference Raia's high heels were factoring in, not just the heights they've had.

"I can imagine you've loved your high-heels," he said. Raia blushed as she saw her breasts welcoming Mark. "My girls like you," she teased. Mark continued to rub his head near her bosom, arousing his sister with the sight. Chelsea overheard Mark's moans and saw how he was. "Aunt Raia, why are you suddenly here," she asked. Mark turned to Chelsea, embarrassed to see her there. "Chelsea, your aunt already planned to go out with me," he said. Chelsea's expression changed as Raia eagerly looked at Mark. "He's my little bro. One day, I think you'll understand," she said while caressing Mark and his hair. Chelsea walked out of the scene, as to give the two privacy. "Dad loves big cats, but why is that especially so for his sis," she thought. Chelsea then went back to creating art as she tried to push back that thought. "Dad, go get her," she quietly said to herself, designing Mark with a 21" penis, which made the pornographer's vagina tingle.

"I don't think I'll share this yet," she teased, chuckling a little. Meanwhile, Raia and Mark were exchanging glances as they ate their food within a restaurant. Mark found time to speak first, after their meals had been presented. "How has Chad been," he asked, enjoying the pasta in his bowl. Raia kept a casually optimistic expression as she was enjoying her plain ramen to eat. "Chad's a cute guy and all that, but he's supportive about my relationships," she said. Mark giggled as his expression changed to a smirk. "Is Chad a cuck," he teased. Raia gave Mark the stink eye out of annoyance. "That idea sounds disgusting! Chad hates the mere thought of him being cuckolded," she said, ignoring the pink nipples that bulged in her bra. Mark continued with his pasta to take a break from discussing Chad with his sister. "What would possibly give you that idea," Raia inquired in a slightly more serious voice. Mark, despite focusing on his meal, gulped his bite of pasta for discussing with her.

"If he's supporting our love, won't that give you a hint or two," he asked. Raia felt embarrassed about responding to what Mark said. "Even if I would be cuckolding him, he's the #1 husband I've had," she said. Mark shook his head, disappointed with her pure hypocrisy. "Remember that divorce with your brother Elliot," he asked. Raia's expression changed to a sad one as her eyes shed tears. "I'm shocked you would actually bring that up right now," she said, crying from when Elliot left her. "Ellie's why he was divorcing me in the first place," she wept, unhappy about the adulterous spouse she used to have. "I still can't forgive them for destroying the family unit," she said, still upset from the cuckqueaning, as some call it. Mark wrapped his arms around her to try comforting his favorite sibling. "Raia, we have been romantic for years. I think you're a beautiful woman, and I'm sure Chad loves you just as much," he said, caressing his older sister's lavender hair. Raia appreciated Mark's attempt, which was a little successful, but she still cried for now.

"Thank you, Mark. I think you've been the best brother from the trilogy of Dad's sons, having saved used from the T.M.I., which I know was very difficult," she said. Surprisingly, their instinctive sides were triggered to let both of them kiss. Mark led this with what he saw as the most attractive tigress within his family. What would their respective wife or husband tell them? Raia avoided the thought of that, but Mark knew his sister's libido all too well. "Mark, I'm sorry if I got too intimate with you," she said. Mark smiled at his embarrassed friend and loved one. "Don't feel embarrassed, Raia; the kiss was consensual. Maybe we got carried away by natural instincts," he said. Raia nodded with a happier expression for a bit, but she saw her breasts covering up the ramen. "Damn it, my rack is too big to see what I can smell," she said. Mark adjusted the ramen bowl's spot so they could both see it. "Can you see your bowl now, sis," he asked. Raia, who was slightly humiliated, just gave a grin.

"Sure, but you did not have to speak out loud," she said, regretting her bigger bust than she used to have. "One too many massages," she thought, remembering when she was getting breast massages from Mark, who helped her breasts naturally grow. Both breasts were naturally big, and have since remained established as such. Ironically, her breasts' authenticity were questioned more frequently after they grew past Raia's old lingerie. "At least my lactation rates have improved," she thought. Raia continued with her meal as Mark has been enjoying his pasta. "Would you like my milk with that," she asked. Mark shook his head, disbelieving what he just heard. "I appreciate that, but I can wait," he said, focusing on his gourmet root beer. Raia had a Plan B, however; she was into seduction at dates. "Gee, I could cool off a bit," she teased, unhooking part of her nursing bra. Mark saw that Raia was persistent with the attempts at seducing him.

"I think she has been in heat all this time," he thought, understanding his sister's much hornier ways. Raia purred in a seductive voice as she and Mark held hands for a bit, as the former was gesturing him to give a hand to her. "Mark, I should clarify something," she said, slightly hesitant to tell him. Mark was studying her body language thoroughly by now; how she bit her lip, nervously looking at him, and so on. "Raia, I already know; you're in heat, and have been from the start of this date," he said. His older sister knew he was great at analyzing details like those; since Mark's aware of her libido, it was difficult to stay civil. "Please, I should probably have this to-go," she said. Mark, who recently finished his meal, nodded as he would trying motioning for the staff. A flamboyant waiter with dyed pink hair saw this as a chance to woo him. "Hey there, my good man; how can I help you," he said to the guest. "My friend and I've considered a meal to have, to-go in this case," Mark said.

The waiter wrote down the requested service and had a curious look. "Is there a particular meal you would like for that," he asked. Raia raised her unfinished bowl to the feminine waiter. "If you can, fresh ramen for me," she said, attempting to keep a straight face. The waiter was ogling at Mark, who felt uncomfortable around most femboys. "Just for you, sir, the meal would be on me," the waiter clarified to Mark, who honestly felt a bit sickened by the hair. "What is the catch," he asked. The waiter was smiling as Mark would ask this. "Catch," he joked. Mark groaned as he looked solemnly at the man. "I'm not used to staff who pay for the meals, so I want to ask this; what made you want to pay," he said. The waiter kept a calm expression as he wrote down the information. "I've worked here for months; plus, I've previously seen you here. This, Dear, is why I sometimes won't mind servicing cute men," he teased.

Mark's expression changed to a stricter one by the choice of words. "Listen carefully; my friend and I want one carry-out order, and the flirting won't help anything," he said. The waiter, realizing Mark picked up on the innuendo, looked very embarrassed at the man. "Sweetie, I'll go fill the to-go request," he said. Mark was motioning the waiter to leave at once. "Thank you; now go pay for it," he said with a stern tone of voice ordering the waiter, as if Mark were his boss. "Will do, sir," the man said. Raia looked at Mark with excitement, interested with how well he did. "You tell him, Bro," she said. The interspecies pair shared one more kiss, this time with both of their libidos talking for them both. "Oh, Brother," Raia playfully teased to her younger brother, who hugged her. Mark felt a stronger connection to her than he did earlier during this night's date. "Sure I'm her brother, but we've already felt so close," he thought. His expression changed as he got the bedroom eyes.

Raia's look was much more seductive at this point. "Chad and I already planned for threesomes," she said. A different waiter, this time one who previously got to know Mark, found him and presented an order, this time carry-out ramen in particular. "Mr. Krieg, I'm pleased to be presenting this to you," he said. Mark's blush faded as he accepted the carry-out order. "Thanks. Here's a tip," he said, exchanging a dollar for the food. The waiter left the two, smiling as he saw a familiar friend give a tip. Raia looked hungrily at Mark, intending to have the ramen that's warm. "May I please have that bag, Mark," she asked. Mark nodded as he delivered the bag to her. "Now that we can leave here, yes," he said. The siblings exited tonight's restaurant as the two teleported to Chad's house. Meanwhile, Chad was very pleased with his bulging erection in his under-garments. "I can't wait to see Mark please both of us," he thought, fondling his nipples as he purred.

Then, the door bell was heard. "What the-? I can't host this yet," he thought as he remembered where his stack of Playmon was. "If Raia saw my porn magazines, some of which have her, she'll be mad at me," he quietly said to himself. He put the Pokemon-themed porn in a drawer and went downstairs, expecting his proud wife. Chad sighed as he saw Raia together with Mark. "I wasn't expecting you two to get here so soon," he said. Raia was enjoying the carry-out ramen when Chad happily welcomed them in. "Mark, I'm pleased to see you come to this house," he said. Mark was noticing Chad's bulge and his fully-erect nipples as he stepped in the home. "I can see why," he teased. Chad blushed as he invited Mark to their bedroom. "What do you think of my room," he asked. Mark smiled as he was relaxing on the bed. "I think the light-yellow colors can work. The sheets' grass-like patterning look great," he said. Raia, who was finishing her meal, laid the bowl on an oversized coaster and took off her top. "Finally, time for letting these get air," she said, unzipping her jacket and removing her breasts' nursing bra.

Chad smirked as his wife laid on the bed next to Mark. "Mark, shall we start," she asked. He nodded and accepted a kiss on the lips. Chad looked shocked at his wife, who was already kissing with Mark. "Cut that shit out," he yelled. Raia and Mark shared lovey-dovey expressions as they looked into one another. Chad began growling to warn the two to stop. "Raia, stop or I am divorcing you," he yelled. Raia immediately stopped the French kissing and felt guilt for her adultery. "I will, for you," she said in a sad tone of voice. Mark felt bad for Chad, who watched them make out on top of his bed. "Raia, why did you ruin our marriage," Chad asked in a stern tone of voice. His green eyes locked at Mark, who was involved with the cuckolding. "What the fuck would your wife say," he asked, furious about what the two did. Mark kept his cool as Chad cursed him out. "Isn't it ironic you've cuckolded many men, but now this is the first time you'll snap, when Raia's cuckolding you for me," Mark asked, curious about this hypocrisy Chad has.

Chad remembered all of the men he would make cuckolds out of, especially married men whose wives grew to love cuckolding. "He's right- I've never been this furious," he thought. To make all of this worse; he just made his wife cry, who has been sensitive to shouting. "Guys, I'm sorry if I've suddenly snapped. It's just that my original, first girlfriend cuckolded me for a human richer and hotter than me. This cuckolding was right before I bought a ring for my then-fiancee," he said, regretting the outburst. Raia, who breathed in and out for relieving stress, hugged her spouse. "Chad, I apologize for my immature actions," she said. Mark got Raia's clothes and presented them to her. "Your upper-garments are here," he said. However, Chad had an alternative idea. "Actually, stay there, Mark. I have a plan for you," he said in a charismatic tone of voice. Raia's expression changed as she felt a different vibe from her husband. "Should I leave now," she asked.

Chad motioned her to leave the bed. "You should probably get off," he said. Raia nervously got off of there and sat down on the floor. Mark saw Chad presenting his big penis to him. "Mark Krieg, I want to be top," he said. Mark's penis was erecting as Chad began removing his pants in front of the two. "That's strange- I'm usually top as well," he said. Chad shook his head, believing he deserved that spot. "Looks like we're both top guys, huh," he asked. Mark nodded as Chad grinned at his friend's erection. "How about nude arm wrestling for top," Mark said. Chad's grin began widening as they both laid down on the bed. "Could you win with your left arm," he asked. Mark, being right-handed, knew Chad's ambidextrous hands would be difficult to rival. "Perhaps that's possible, too," he said. The two men went to a nearby tabletop and laid their respective elbows on it. "Good luck, Krieg; you'll need it all," Chad said.

Mark gulped a little nervously as Chad seductively purred. "Yep," Mark said. At the sound of Chad's "Go!", the two competitors began arm wrestling; it was surprisingly even at first, but Chad's mental state was weakened, which made it easier for Mark to arm wrestle. This handicap would be Chad's downfall once Mark's left foot stepped in closer to part of the tabletop. This gave Mark enough energy to slam Chad's arm onto the tabletop. Chad was shocked by his first loss in months. "Now I know you're the real Mark Krieg in here," he said. Mark smiled at the kind compliment. "Thank you. I kept my composure intact," he said. Chad nodded at Mark's suggestion and presented his pink tail-hole to Mark. "Here is your prize," Chad teased. Mark remembered a condom he brought with him so that he would not impregnate women, or catch HIV/AIDS. Luckily, neither scenario was applicable here. "Chad Purrcision, how about we go back to your room so I can pound you there," Mark asked.

Chad accepted Mark's offer as the two went back to Chad's room. Raia was awaiting them, this time with calmer expressions. "Who won the match," she asked. Chad smiled at Mark, who was fondling his balls. "Mark won the match," he said. The men got on the bed as Mark began anally penetrating Chad, who laid down for doggy-style sex. Mark's hands began fondling Chad's breasts as he anally pleasured his friend. "Enjoying the ass pounding, my new pet," Mark teased. Chad's expression changed to a smile as Mark continued stimulating his prostate. "Deeper," Chad requested. Mark happily obliged as Chad took a 20-inch boner in his ass. Raia watched with excitement as Mark fucked this furred beast into submission. "Take it, you cuck," he teased. "Yes, Daddy," Chad responded to Mark. Raia's jaw dropped from the trash-talking, which was much more than unexpected. "Chad lost his mind," she thought.

Seeing her husband get buggered by Mark was probably the least likely of what possibly could have happened on this night. Mark playfully tickled Chad's belly as he sodomized him. "Chad, should I jack you off, too," he asked. Chad purred delightfully as he verified consent to him. "Sounds Purr-fectly swell, Master," he said. Mark started fondling Chad's big balls, then eagerly gave him a hand-job. Chad panted heavily as Mark made his dominance aware. "Suck that off for me, will you," Mark asked, bringing the erection to Chad's mouth. He started the atuofellatio as Mark helped with this. Chad wasn't used to the auto-fellatio, but his goal was satisfying Mark, even if it meant swallowing all of the cum that would ejaculate in one load. Mark still gave a hand job, due to wanting Chad to orgasm. However, Mark planned to conserve his load for now. Chad was already close to ejaculation, this time from multiple stimulation sources. He chirped as he came in his own mouth, allowing his cub batter to go down his throat.

Mark pulled out of his pet and pinched Chad's ass, signaling him to turn around and face him. "Your ass, honestly, could have been better. However, I enjoyed its tight walls," he said. Chad smiled as he looked at his dominant man. After swallowing more of his load, Chad took his dick out of his mouth to speak to Mark. "Master Mark, is there anything else you want to do," he asked. Mark shook his head, satisfied with the anal sex. "No thanks, but I think I'll clean up a bit. Then, when I'm done, I think we'll be continuing," he said. Chad nodded in approval, delighted for a second round. "All right! I'm also up for role-playing," he said. Mark left the room, signaling Raia to keep an eye on Chad. "Big Sis, feel free to make sure Chad stays comfortable," he said. Raia obediently went with Mark's order, attempting to keep her husband comfortable. "So, what was it like to catch," she asked. Chad's facial expression kept its optimism as he looked at his wife.

"Mark's somebody I would get on my knees for again," he said, blushing as he imagined Mark cuddling within his bed. Raia felt a sense of confusion as to why Chad was calm. "Chad, is everything OK," she asked. Chad continued with his smile as he nodded eagerly. "I honestly hated his guts because of the cuckolding, but now I don't think that it was his fault. After all, you made the advances, to which Mark himself consented to," he said. Raia hugged Chad, who was glad that he started forgiving Mark for the aforementioned cuckolding. "I can't say mad at a cute guy like him," Chad said. He saw Mark return, who showed both of them a bigger penis. Raia blushed immediately upon the sight. "Who is that for," she asked. Mark blushed as he began motioning for his pets. "How have you romantic pets been doing," he asked. "Good," Chad said. Raia felt her clitoris get hard as Mark hugged both of them. "Chad, Mark; would anyone like a threesome," she suggested to her lovers.

The two men smiled in agreement as they looked at the girl. "Mark would you like to lead this," asked Chad. Mark nodded as he laid on the bed, requesting the two to join as he patted his hand on two areas of the bed. "Chad, you can get back on your knees," Mark said to Chad, who went along with his commander. Raia's tail rose, excited to see what Mark may plan for her. "Raia, I've been preparing for you, too. How about vaginal," he said. Raia blushed heavily as Mark's erection started penetrating her. "Absolutely," she said. "Chad, why not orally lick her pussy as I get some with it," Mark asked. Chad obeyed, ignoring some reluctance he has been feeling. "Yes, sir. I'll go start the cunnilingus," Chad said, putting his mouth on the vagina Mark was penetrating. Raia was not used to incest with her brothers as Chad orally pleased her pussy. "Both Mark and Chad around my vagina- What a treat," she thought.

Chad hated submitting to multiple people, but he actually got to orally pleasure his wife out of this. "Raia's clitoris could use a nice flick," he thought, tickling it with his hungry tongue. Raia was closer to an ejaculation than Mark was from the flick of the clit; but, this was not a race, so Raia was having multiple orgasms as she eagerly waited for Mark. Some of these were meant to lubricate his manhood, or possibly giving Chad bonus pussy-juice to slurp up. "Oh, Mark," she groaned as Mark did her doggy-style. Chad ceased suckling her erect clit and stood up from the bed. "Master, when will my wife be rewarded," Chad asked, challenging himself to keep a straight face for now. Mark grabbed Raia's desired breasts and began fondling them. "Does that feel good," he asked. Raia purred from his pleasurable handling of her breasts full of milk. "Please, make me roar for more," she kindly requested. Mark, out of irony, obeyed and blew a huge load in her.

A loud, pleasure-heavy roar from her filled the room as Mark's orgasm hit her G-spot. Mark brought his erection outside of her cream-pied vagina and began motioning Chad to come back for more. "Lick that up, Chad," Mark demanded from his lover. Chad nodded as he attempted to eat her out. "Geez, his cum tastes great with that," he thought. Raia moaned louder as Chad dined on more pussy. "Mark, is it wrong if I want you to get fellatio from me," she asked. "Please, see what your mouth can take," Mark teased, entering her mouth by wedging his pre-lubed erection in between her saber-teeth. Raia normally did not like fellatio, due to her saber-teeth usually getting in the way; however, some men have received fellatio from her on a good day, especially if they bypass her saber-teeth. "Mark's extremely lucky that I would do this for him," she thought, remembering the saber-teeth that get in men's genitalia's ways. This made Raia's preference to get oral sex from a masculine man, established understandably so.

Another reason is that she sometimes felt that urge to dominate Chad, who grew to love muscular women. "Good kitties; you know who's the dominant man in here," Mark teased. Raia deep-throated Mark to give him the most satisfaction, but it was impossible for her deep-throating him balls-deep, due to the erection's insane length. Mark finished her off with his next, bigger ejaculation. Raia felt him pull out instantly, once he came in her mouth. "Chad, you can probably snowball her, right," Mark teased. Raia consented with a nod and gulped a little cum by accident. "I would, but I accidentally swallowed semen," she said. Mark and Chad shook their heads, embarrassed about Raia swallowing Mark's cum. "Chad, I'll just go," Mark said, gathering his clothing as he teleported back to his house he's had. Raia looked heartbroken at her spouse. "I screwed up twice already, didn't I," she asked. "Yep. I think I'll go sleep now," Chad said, cleaning his erection he still had.

Meanwhile, at home, Ginger had Mark helping with handling a breast pump. Ginger's lactating breasts felt the stimulation as Mark began fondling her breasts. "Mark, thanks for returning while I'm up," she said, lactating into the breast pumps' "horns", versus an alternative such as breastfeeding. Her husband blushed as he happily groped her breasts. "Gin, now it's just both of us," Mark said. Ginger let his hands start assisting further with massages. "Mm-hmm, I think your hands are wonderful with my bust," she said, excited for her husband's swell hands. "I've known your breasts' well for years, but that's partially thanks to generosity," Mark said, caressing his wife with his fingers. Ginger squealed a bit, delighted as he helped out with breast stimulation. "I've been studying the science for why I have breasts, but I'll only need one assistant for that. Nevertheless, Mark Krieg; you've filled that role," she said, admiring everything the couple went through, but remained together after Mark's revival.
