Raia's Motherly Side
Raia has been Mark's mother figure for a long time by now. Just how "motherly" is Mark's sister?
It was a quiet evening for Mark and Raia. As they snuggled in the latter's bed, they discussed a few things.
"Mark, darling~"
"Yes, Raia?"
"Why are you and Mrs. Krieg tolerating these dates you and I have had? We're even snuggling after a romantic date we just had earlier today."
"For starters, we've sometimes been in an open relationship, except Gin's never cheated on me."
"Well, all right; isn't it strange she's tolerant of this interspecies relationship? After all, I'm your older sister!"
"Raia, I know I'm your younger brother and all, though at least you have me to love you."
Raia remembered how Raio and Elliot, her brothers who've married each other, were happily married. As Elliot's ex-wife, as well as the mother of their daughter Ellie, she knew Mark had a point. "Listen, Darling; you've known me better than almost anyone else could have. You know just how lonely I have sometimes become. To make matters worse, I'm not desired as much, since I've already been a mother," she said reluctantly. Mark noticed her alternating body language.
"Raia, is anything wrong right now?"
"Erm... How can I say this? I've felt so fond of you."
Raia paused as she looked embarrassed, having fallen in love with a young man aged younger than her. Mark comfortingly hugged his big sis.
"You don't have to feel so embarrassed about the love you have."
"Really? I've been your mother figure, as well as your paternal sister."
"You are also Raio's female equivalent, and just as smart as him. That has also made you lovable."
Raia purred with happiness as she heard him out. "Darling, I will always love you, too," Raia said. She proceeded to remove her sports bra as she gave it to Mark, who happily set the bra on her dresser. Mark knew she wanted mammary stimulation, so he took off his garments to make room for his erection. Raia proudly went along with this; they have sometimes been practicing this.
"Brother, darling; would you tease your sister with that? I know you can help make my breasts stimulated!"
"How long do you want me to make this?"
"A foot or two, I think."
As Raia watched his erection grow, her jaw dropped. Her brother may be a semi-god with some flaws, although this was exciting for her! Would God forgive them for their consensus, incestuous relationship? Feeling a bit worried, Raia primarily focused on Mark to distract her mind from the fear of damnation. "Ready for Mama's MILFy breasts," she teased. "I think so," he said. She hugged his penis with her breasts, longing to share a tit-fuck. She licked his warm penis' tip as he squirted some slight pre-cum. She licked that up as she kissed his tip. "Ooh, Mama's going to enjoy her treat she'll have soon," she said as they continued milking his cock. Mark kept thrusting as Raia kept milking his cock with her breasts, albeit sometimes her tongue as well. This only lasted half an hour, but Mark came on her breasts probably a couple quarts of cum to please her. "You're really messy today, aren't you, Mark," she teased. "Don't worry; you may shower with Mama," she said as she took off her pants, alongside her panties and foot wear. He happily nodded as they traveled into her bathroom.
After the shower got warmed up for long enough, they both happily walked into it. Luckily, the siblings could simultaneously share the shower stall, so space wasn't even an issue. Mark groped Raia as she purred happily when he groped her hips. "Mama loves getting wet, now, doesn't she," he teased, playing along with the foreplay his older sister started. She grinned as Mark rubbed her nipples, feeling the warm water heat up her breasts. Since Raia pumped her breasts earlier, she wouldn't be lactating this time. As Mark teased his elder sister, she started to loll her tongue, having felt excited from this stimulation. "How do my hands feel to you," he asked. "Erotic," Raia said. This surprised Mark, who had expected a word describing texture, like soft. "Raia, is everything fine," he asked. Raia nodded as she knelt and presented her vagina. "Mama's offer includes this ," she said. Mark knew she wanted vaginal penetration, but thought he could get more out of this. "Would you throw in the breasts, too," he asked. "They have no milk," she said with a frown. Mark loved adult breastfeeding, but he also loved breast-sucking. "That's fine, they still look extremely fun for playing with," he said as he licked her big tits. She moaned pleasurably, knowing how ticklish her nipples are. Mark enjoyed orally stimulating those breasts; despite Raia having pumped her breasts, her nipples have tasted very sweet, like her milk. As Raia moaned, Mark moved onto sucking her breasts. As Mark held her backside onto the shower stall's wet wall, he continued playing with her delicious nipples. "Oh yes; dominate Mama! Make her beg for erotic incest," she groaned as she happily held Mark's shoulders close to her. When he stopped sucking on the breasts, Raia looked at him proudly. "Mama's also longing for that soft cock," she said. Mark noticed his erection he got. "So, wanna fuck Mama," Raia asked, expressing bedroom eyes as she blinked. Mark pinned her against the wall for vaginal penetration, and secretly giving her extra orgasms just from her male dominance fetish; pinning her against the wall as she's getting fucked, giving her orgasms from his domination; this is something she secretly loves, alongside alpha men. "Fuck yes, Mark! Make me even hornier," she begged, feeling her orgasms amplifying her love that she has had for Mark. As she came on his cock, Mark tickled her erect nipples more, still pinning her against her own shower stall's wall. "Does Mama love to be fucked by a patriarch," he teased her. Raia squirted again as he continued thrusting his cock, continuing the cycle of her orgasms. "Oh, Mark," she screamed in joy as Mark then blew his load and filled all of her cunt with his seed. "Oh my," she said, watching her legs shaking fiercely.
"You got Mama's hips gladly shaking."
"Raia, I knew you wouldn't resist this incestuous experience. Feels good, right?"
"Oh, it does! You've made me so proud, Mark. I'm dripping wet with extra semen. This feels great!"
"Your pussy's still extremely tight. Raia Blitz Krieg, our foreplay went well. Given your assets, you're an A+."
"Why thank you. I have enjoyed patriarchs like you, since I've admired men with power But you've also been a semi-god, but often outranked by both Our Lord and God. After them, it's been extremely ambiguous, although that would be excluding you. As Matriarch of the Krieg Brothers, I have frequently kept high standards. My best bet is you, Mark. I'm kneeling because of the extra weight that transferred to my vagina. I don't even have eggs anymore, so I'm not even getting pregnant. Ah, the shower water's feeling nice. You know, I enjoy consensus domination, because it is probably a kink I have had."
"Well, Gin's probably waiting for me: I have about an hour before I'll see her. See you soon!"
As Mark walked out, he winked at Raia, who happily winked back. After drying off and then putting on clothes, Mark teleported back home. After all, he's Mrs. Krieg's husband, and he sometimes won't like to keep others waiting.
"There you are, Meister!"
"I know I'm slightly early, but that probably works better, right?"
"Oh, of course!"
As the married couple hugged each other, they felt a slight breeze. Mating season will be coming up, and Mark remembers Gin's high libido in mating seasons. "You know, Meister; we could snuggle tonight," Gin said. "That is indeed possible," Mark said. "So, how have your sexcapades been today," she asked. Mark blushed and felt somewhat embarrassed. "Raia and I shared a lot more than one orgasm," he said. "Oh my; you two make a good team as well," she said. "Well, she does act motherly towards me," he said. "Motherly," Ginger asked. "It's difficult to explain," he said with an embarrassing blush of his. "Personally, I understand if it's Lily who's acting motherly, but Raia? That's indeed something," she said. "Raia and I do enjoy foreplay," Mark said. "That may explain her, say it with me, motherly side," she said.
