21st December

Vince woke up when the sun was already shining through the window. The curtains were pulled open and Vince suspected that either Lilly had opened them or Stacy. Blood rushed into his head when he realized that he still lay in the bed of Tracy with his slick member pressing against her tail base. It slipped out overnight but while he had been half awake it seemed to have slipped out from her alluring smell.

Lilly bounded into the room and saw that he was up. "Good morning Vince." She shouted and that also woke up Tracy. "Good morning Lilly." Vince voice was still a bit sleepy and it took Tracy a minute before she also returned the greeting. "Mom is out shopping with Sarah. I think Mia and the others went with them. I did see them at the car at least." - "Why are you not with them?" asked Vince. "Mom said that she thinks I might have caught a cold and that I should stay home. She said you two are to play with me." She handed a letter from Stacy to Vince but Tracy grabbed it. Vince, who still had his head lying on her shoulder, read the letter in her hands.

Hello Vince, hello Tracy,

Sarah and I are going to the city to do some shopping. We might also visit the Christmas Market so please watch Lilly. She said she feels good but I am not sure if her sore throat yesterday was just the first sign of a cold. I want to make sure she does not get even worse for today. There is some food from yesterday in the fridge. You can warm it up for lunch.

Please make sure to play with Lilly so that she does not get bored and don't stay all to yourselves all day long. If we go to the Christmas Market it can get late.

See you this evening

Stacy (Mom)

Tracy let the letter fall to the ground. "So?" she asked. "What do you want to play Lilly?" Vince caressed the dugs of Tracy what earned a low moan from her. "I want to watch you do what you did this time in the bathroom." Lilly directly responded. Vince chuckled and Tracy sighed. "Well fine with me." Said Vince. He did not mind the girl watching. She had seen it already anyway and in a sense it made him a bit aroused to think about Lilly watching them mating. "I think we can't help it." Tracy sighed again. Vince took this as a yes and directly started to move his paw to her clit. Her pussy was drenched from her heat and a bit sticky from his spunk of this night. Tracy moaned loud and pushed her back against the belly of Vince. He threw the blanked off them and Lilly squeaked in surprise when she saw that both of them had their lower half exposed and his member was already rubbing at her slit. Vince prodded a bit at her entrance while stimulating her clit until he could not bear it anymore. He rolled Tracy on her stomach and lifted her hips with his paws before taking momentum and pushing in to the hilt. His knot did not form yet so he collided with his hilt against her wet pussy with a smack. After a few pushes and strong moaning from both older cubs Vince felt a paw on his shoulder. He looked to the side surprised. Lilly looked at him with an unhappy face. "I can't see." She complained and Vince understood that with the bed being close to the wall she was unable to move behind them and from the side the vision was mostly blocked by their legs. Vince used the artificial break to also pull the nightgown of Tracy over her head and slip off his pajama top. He thought about what to do. To be honest he did not want to pull out of Tracy to go into the bathroom just for Lilly. On the other hand he did not want Lilly to feel left out because he still was concerned that she might slip something about them letting her watch to her mother.

"The only way I see then is for you to lay under Tracy with your head under our hinds." He suggested after a while. Lilly agreed faster than Vince would have thought. Tracy seemed to have the same concerns than Vince in excluding Lilly now and moved her upper body up to allow Lilly to crawl under her. With Lilly being a head smaller than Tracy there was no problem in her fitting under her bigger sister. Because they were very close to the head of the bed she had to spread her legs to not have the shank cross over the bed edge which would be painful from the pressure if she did it for a longer time. Vince saw her nightgown spread but still cover her nether region. It aroused him a bit to see the small girl spreading her legs so far. It was like she was getting ready for mating. Without further hesitation he started to pound into Tracy. Both older cubs moaned and closed their eyes while Lilly eeped a bit from the slashes of girl juices dripping down from Tracy's snatch on her face. Vince and Tracy did not regard the smaller girl under them and just moaned and engulfed into their act. Vince picked a strong pace and Tracy met him with pushes to get him as deep as possible. She was as horny as Vince right now. The male wolf pup felt his knot beginning to form. Tracy moaned strongly by the half formed knot pushing in and out of her pussy already beginning to stretch it a bit. When his knot slipped in and locked them together he stayed motionless and waited for his release. Suddenly he felt something press the knot from below. It took him a few seconds to realize that it was the tongue of Lilly who licked the fur and skin of Tracy where his knot was. The imagination and extra pressure sent him over the edge and he spurted into the womb of Tracy which triggered her climax soon after.

Vince moved a paw towards the nether region of Tracy and felt the little muzzle lick the fur. He pushed the yaw a bit more down. "Try to lick the nub of your sister down there." He asked Lilly. "No Lilllyyyyyy..." Tracy's complaint turned into a long and strong moan and Vince knew that the little girl found her clit. He felt Tracy contract even stronger and then suddenly he felt a strong hot stream against his balls. He knew that the orgasm of Tracy had been so strong that she could not control her urge to pee. She soaked the head of the surprised Lilly and the sheets with her strong smelling water. The scent of heat was all around the head of Vince. He heard Lilly cough and snort. It seemed the surprised cub got some of the urine into her muzzle. "Sorry Lilly." Huffed Tracy when she came down from her moans a few minutes later. Her sister did not answer and Vince looked under Tracy. Lilly still looked surprised and coughed a few times. Her head was drenched from her sister's pee. When his gaze went up a bit he saw that her nightgown was not over her snatch anymore and the area around it was drenched in her own fluids from the arousal of their mating. The little girl seemed to have masturbated because her paw was over her slit and drenched as well. "I am also sorry Lilly. It was my idea after all. What do you say if I make it up for you by licking you like before to make you feel really good after Tracy and I are done?" Lilly nodded and her eyes glistered. Tracy did not comment his offer but moaned and rode out her orgasm. Vince felt a tongue lick over his drenched balls. Surprised he looked under Tracy again and saw Lilly lick them clean. "You don't have to Lilly." He comforted the cub but she only stopped to tell him "Well if you make me feel good I help you feel good as well, right?" Vince could not argue with her logic and also did not want to. It felt nice to have the small tongue lick his balls and he enjoyed the fifteen minutes he was stuck in Tracy. Her tunnel twitched now and trying to milk more out of him long after his spurts stopped and the tongue continued to lick his poach, balls and from the moans also the clit of Tracy. Lilly started to gargle a bit when his knot was small enough and Vince pulled out. He did not regard the cub and that his cum would flow out of Tracy and it must have splashed directly into the open muzzle of Lilly who still licked his balls before she was able to close it. Vince got up from the bed and Tracy also quickly clenched her slit and got off to allow Lilly to stand up as well.

"Are you okay?" Vince asked concerned and licked the closed muzzle of Lilly that still had traces of his cum. It tasted also strongly like the urine of Tracy so he stopped after a few licks. Lilly surprised him by pushing her head forwards and her lips on his in a kiss. He put his arms around her and returned the kill while he caressed her back to make her feel comfortable. "That was surprising." He gasped when they were finished with the kiss. Tracy looked a bit upset about it. Vince also saw that the nightgown of Lilly was now sticky and slimy at her stomach because his member had pressed against her. "I think we should go to the bathroom." Suggested Vince. "Tracy can take a shower while I fulfil my promise, okay?" Lilly smiled from one ear to the other and Tracy just grunted her approval. She still seemed angry at Vince for the kiss with Lilly and that he did not even mention it.

They all went to the bath room and Tracy vanished in the shower and pulled the shower curtain close so that they could not see her and she did not have to see them. Vince shrugged with his shoulders and helped Lilly to disrobe. "Crouch on all fours like your sister before and I will do the rest, okay? You can moan as much as you want and you can close your eyes." Lilly was eager to follow his advice and Vince moved to her hind. The moment he got his nose close to her drenched pussy he noticed something. A smell that was clearly different from the smell she had before. It smelled a bit like her sister. Maybe she rubbed some of her sisters juices there? "Erm, Lilly, did you feel any different this morning?" he asked to just make sure he was not imagining it. "Yes, it went wet and I felt strange and there is a weird itch there." She pointed at her pussy with her paw. "Is this bad?" she asked worried. Vince pushed his tongue into her snatch up to her hymen and made her moan. The heat inside her left no doubt. He pulled out his tongue. "No, I think you might just have gone into heat. I am just surprised because you are still much younger than your sister." Vince remembered something they learned in sex education in school that it could happen that females went into heat because other females did. He also remembered that this happened in his class that when one of the girls went into heat even the younger ones were in heat a few days later and they parted boys and girls until it wore off. He had just thought this happened by chance back then but either Lilly was just naturally very pre-matured or something was right about this theory.

Lilly turned her head and he could see from her smile that she was rather happy than confused or frightened by his diagnosis. "So this means you will do the same with me that you did with Tracy, right? You promised!" Vince was a bit taken aback. He forgot that he actually promised that and was very surprised by Lilly remembering this now. "Well... I guess so..." he responded slowly and looked up to the shower. Tracy seemed to not have listened to them and with the shower running and them talking very silently it was possible that she did not hear them. "A promise is a promise." He said with a smile which made the smile on Lilly's face even brighter. He started to whisper. "Okay but even if you in heat it might hurt a bit at the start. You should put this into your muzzle." He explained her and handed her nightgown to Lilly. "I will first make you feel good with my muzzle and then I will do the same I did with Tracy, okay?" She nodded with a gaze that was telling Vince that she understood that he did not want to alarm Tracy. She made a ball out of her nightgown and put it into her muzzle. Vince made sure that she still was able to breathe through her nose. Then he went back to her hind. Her scent was fresh and innocent like the scent of Tracy had been. The member of Vince directly got erect again and he felt the pressure at his base increasing which told him that his knot already prepared to fill. He continued to lick Lilly and push his tongue into her hot snatch. The scent drove him crazy and her taste was like honey in his muzzle. He could hear her muffled moans and kept an eye on the shower. Tracy seemed to not plan to stop her shower any time soon. He suspected that she did not want to see Vince licking her sister now and just idled the time under the shower to have a higher chance of not having to look. It worked for Vince as he was sure if she saw him mounting her sister she would try to stop him. From the earlier arousal while watching her sister and Vince from close it did not take Lilly long to get her climax. After a few splashes of her girl cum she started to pee like her sister because it felt too good to hold in. Vince continued to lick her tail-hole and slit until the stream subsided. He licked off the remains of her urine and moved her a bit away from the puddle of her yellow water.

"Ready?" he whispered and Lilly nodded with her muzzle still muffled by the gag. "Remember this might hurt for a bit. Bear with it okay?" She nodded again but Vince decided to play it safe and when he mounted her he bit down at her neck to keep her still. When he pushed in hard and popped her cherry he heard her muffled scream and massaged her erect dugs with one hand while he moaned soothing words into her ear. She was even tighter than her sister but he went in so fast that he felt his tip already breach her cervix before her muscles clamped. He waited until her muscles relaxed a bit before he started to move slowly. She did not scream anymore but groaned and sobbed like her sister did. "You do wonderful." He whispered into her ear. "It will soon start to feel good." And with this he established a slow pace with small movements in and out. He bottomed out with still a few millimeters to go to his knot and he started to wonder if he would be able to knot Lilly at all. Not only was she not as deep as her sister, and it had been a problem with her as well at first, but also much tighter. For now he just went slow and felt her tunnel relax a bit and twitch from the stimulations. Her subs vanished and turned into moans and groans mixed. He still felt that her tunnel stretched tightly around his member. He felt himself come close to his own climax and started to try pushing in his knot. He managed to push it up to a third with a lot of muffled groans of Lilly but finally had to come to the conclusion that the girl really was too small for his knot and he also did not want to hurt her. Her pussy lips felt much more stretched already with only a third of his knot in and he also felt that her womb would not stretch much further inside. He pulled back until only the edge of the knot was in her and then let go of his spunk. The little girl came at the moment he released his sperm. She clenched around his member and because of her tightness the seal at her pussy with his rod was enough to prevent anything to spill.

"What are you doing?" The voice of Tracy sounded hysterical and Vince looked up as well as her sister. She just exited the Shower and looked at the mating couple to her feet. "Erm... let me explain this to you..." - "You better have a good explanation Vince." She replied and Vince pulled out of Lilly who pulled the gag out of her muzzle and helped him. "He just fulfilled the promise he gave me. I asked him to do it." - "What promise?" shouted Tracy. "Well..." Vince started hesitantly. "You know... your sister also got into heat... and I promised the other day that if she did..." Tracy finally understood. Her grimace got a bit softer but she still seemed to be upset. "I can see that she cried. You did hurt her a lot by trying to fit into her, right?" - "No!" Lilly helped out. "It did not hurt..." the raised eyebrow of Tracy stopped her sentence. "... okay it hurt at the start but it felt wonderful afterwards. Just like he said it would. Please Tracy, don't be angry at him. He just fulfilled his promise and..." - "I am not angry." Tracy stated but Vince still saw traces of her anger in her face. "See Tracy, I am sorry. It was just so sudden. The smell... and you know it is hard for a boy to control himself with a girl in heat directly in front of him... and she asked for it and... I am sorry." - "Not only for the boy." Tracy commented his explanation and softly went with her paw over her snatch that was not only wet from the shower. "It is okay." She said a lot softer and her face also relaxed. "I just was surprised and did not know she was in heat and... I was a bit jealous." She admitted. "So you got your first heat as well?" she asked Lilly and they put their heads together and giggled until Tracy noticed that Lilly still had the half dried urine in her head fur. "Eerw... you should shower girl. And while we are at it you definitely as well." She shot at Vince. "I will make breakfast. And no more playing without me!" she commanded when she grabbed the fur towel and the fur dryer and started to dry herself off. Vince did not respond but just followed her request. He helped Lilly inside the shower and helped her to get her fur clean with the soap. And this time he just concentrated at soaping and showering with the girl that was with him instead of following sexual urges. They left the shower fifteen minutes after Tracy clean and dry and went to their room to put on some clothes.

At breakfast the girls and Vince decided on peace again and renewed their friendship with a hug. Tracy was not angry anymore but seemed more excited now to share Vince with her sister. She told her sister that even for her the knotting still hurt a bit but only for a very short moment and then it would feel even more wonderful. Lilly wanted to try knotting as well after she heard that this was feeling good for her sister but they had to give up after a few rounds of trying. The furthest Vince got in was a bit under half but not only was the stretching hurting for Lilly but Vince also was concerned that her womb might take damage because he stretched it strong with his member. In the end they decided to run around in the house naked and whenever one of the girls was ready for action Vince was happy to comply. With two girls he had even more work than with Mia at the last day. The sisters were not as demanding, he had been the one demanding each time the day before with Tracy, but in total Vince got more rounds in sum with both of them than with Mia. He did not mind too much because he was horny nearly all the time with two kittens in heat around him. They did not mate every time but also tried different petting games or oral. Lilly was much more experienced here because of her introduction into sex. Tracy did not manage to take his knot at all and Lilly bragged about her taking the knot in her muzzle even thought she was not able to take it in her snatch. She deep throated Vince once more but this time Vince made sure to only knot her at the very end to not have her throat being sore again. Also he left the control to Lilly and even stopped her from overdoing it.

When the kids heard a car driving by the house they peeked out of the window and saw that it was Sarah's car. They quickly got into the shower to wash away their smell and when Stacy opened the door and greeted them shouting to get them down and help her with some bags they were already clothed and presentable without giving hints to what they did this day. At dinner they slipped their tongue though about the heat of Lilly and Stacy directly confirmed with a look at the girls and Vince that the older cubs had included her into their 'games'. This evening she sat together with the kits and gave Lilly the same talk she gave with Tracy but this time Vince was allowed to be with them. Basically it was the same she told him. That different species could not cross breed and so it was okay with Vince but that she had to be careful because Vince was much bigger than a snow leopard. On the question how she knew it Stacy decided to reveal to her daughters that he helped her through her heat as well. Vince was a bit embarrassed but the girls directly wanted to see their mother do that with Vince as well. Even though she was not in heat she agreed with showing them once and the boy did not object in the end. He enjoyed mating with the beautiful snow leopard lady while she explained different pleasure spots and techniques to the girls that they wanted to try out directly. The older woman praised Vince from his judgement to not knot Lilly and checked out her pussy while he tried it again. She decided that maybe at the end of the heat it would possible but she shared the same concern as Vince about her depth. Lilly wanted to proof to her mother how good she was at giving Vince a muzzle job and convinced him to give a presentation for her mother. Stacy did not stop her and told them to try out whatever they want as far as they were careful not to overdo it. The three promised to be careful and Vince was surprised by the open minded approach Stacy had towards sexual experiments of the cubs.

"Just make sure to not do this with Miles when you are in heat." She demanded at the end. "He will get you pregnant and for that you are still too young, okay?" Tracy and Lilly promised her that they would not jump the snow leopard boy. "We got Vince here, why should we search for someone else." Tracy chuckled but Vince was sure that Stacy said this not for their current heat but for the times when he was gone. This reminded him that he only got 4 days left with them. On the 25thhe was scheduled to be brought to the city by Stacy and take a bus back home.

The bed was a bit craped this night because both Tracy and Lilly demanded to sleep with him in the same bed. In the end they all three ended up there. He pushed into Tracy because knotting with Lilly was still not possible but his arms were around both girls. Tracy lay atop of him and Lilly in his arm snuggling her head against his shoulder and falling asleep while he caressed her nipples and clit softly. Like the day before Vince fell asleep while still being tied with Tracy.
