20th December

Vince woke up in the dark again. Soft paws pushed his shoulder and the whispering voice of Tracy reached his ear. "Vince, wake up." He rubbed his eyes and opened them with a yawn. "What is it Tracy?" he asked and turned to her. The girl was close to him and her eyes looked into his. "It itches so strong." She explained and Vince noticed the strong smell of her heat. "Can't you help me like yesterday?"

Vince did not need any convincing. He got up and followed Tracy into the bath room where he directly let loose of his pajamas and pushed her nightgown up. His member was ready for action and Tracy was so strong in need that she directly dropped to the ground and raised her butt and tail when the nightgown fell on the ground. Vince moaned in unison with Tracy when he pushed in hard and his knot hit her pussy with a wet smack. She still groaned at each time he spread her pussy with his knot but the groans were very low and the moans silenced them soon. Tracy got used to the short pain of his knot stretching her lips. When he finally slipped in her moans intensified and she came to her climax when his spurts in her womb started.

When Vince sat back and took Tracy with him he noticed that the bathroom door was a bit open. He could swear that he saw a pair of eyes for a moment. Scanning the door from the corner of his eyes he caressed Tracy's clit and moaned from the feeling of her insides milking every spurt out of his member. "You can also come in to watch." Vince suddenly said loud when his last spurts hit the womb of Tracy. It took his partner a few seconds to realize the door and like Vince she waited if the silent observer would come in. It took two minutes until the door slowly opened and Lilly entered the bath room. Even if blushing was not visible because of the fur from her expression Vince knew that blood rang in her ears and rushed into her head. "Close the door and come over." He invited her and the little girl complied. She watched him caressing Tracy and both of the older cubs moan in pleasure but it took her a few more minutes until she finally was able to speak again. "What are you doing?" she whispered. "We are mating." Was the answer of Vince while he felt his knot beginning to deflate. Lilly let out a short surprised noise and Vince suspected that she at least knew what mating is. "This is helping your sister through her heat." He explained further. "When a female gets into heat it can be unbearable and then she is happy when she got someone to make her feel good." Tracy found her words as well and helped him to explain her sister about their actions. "See, it feels like a strong itch and he is helping me to turn it into a wonderful feeling until it is gone." She added. "At least for a while." She moaned when Vince continued to play with her clit. His knot was now nearly gone and his spunk ran out of her at the edges of his member. His balls and the ground below were drenched in sticky fluid in no time.

"What it this?" Lilly wanted to know and pointed at the liquid. Vince smiled while he explained it to her. "This is called cum and by putting this into your sister I help her to fight the itch." - "And that makes you feel good?" the little cub wanted to know from her sister. "Oh yes, it does. Extremely good." She moaned still being teased by Vince. Vince felt his member retreat into its sheath and slip out of Tracy's pussy. A last gush of semen and fluids soaked his balls and then her folds closed and sealed the rest inside. "Can you put this into me and make me feel good as well?" the little girl asked and Vince stopped his caressing totally surprised by this question. "No!" he said with weight in his voice. "You are still too young. When you are in heat maybe but without the heat it would just hurt you." Vince was sure that even with the heat he did hurt Tracy when he first entered and knotted her but he was sure that Lilly would not press the issue when she heard that it would hurt. But he was wrong. "But I also want to feel good." She said with a loud voice and Vince and Tracy put their paws forward at the same time to muffle the loud shouts of her. "Psssst." Said Vince. "Don't wake up your mother." "If you don't do the same to me that you did to her I will tell mom." Lilly answered with a more silent voice this time. The girl was very headstrong. Vince pondered while Tracy moved off his lap and took Lilly in her arm trying to make her understand. "You are not in heat Lilly. You only do that if you are in heat, do you understand? It would be bad if he did that with you now. You would be seriously hurt." Lilly put on a sulking face that said the same she did before. If she would not get what she wanted she would go to her mother and tell her everything. Vince was not afraid of Stacy getting note of his actions with Tracy. He was sure Stacy knew about it anyways. He was more afraid about the fact that Lilly saw them and wanted to tell Stacy that. "Hear Lilly? I promise you when you get into heat and I am around I will do the same to you, okay?" The chances were very slim that he was around in a few years so he thought that this was an empty promise anyway. "No, I want to feel the same now." Lilly demanded. Tracy tried again to convince her. "We can't do that Tracy. You are too small." - "I am not." Lilly said with a sulky voice.

"Wait." Said Vince who got an idea. "We can't mate but I can make you feel good in another way that is close to this." He offered. Tracy was not taking this. "No Vince, she is too small!" she said again. "I am not! If you can do it, I can do it too." Lilly repeated and Vince saw that none of the sisters would go back on their opinion. The last thing he wanted now was a cat fight between the sisters. "Let's make a bet then." Vince offered. "If you can show me that you are a big girl I will make you feel good. If you can't show it to me I will not do it." - "How will I show it to you?" Lilly saw a glimmer of hope. "Well..." Vince pondered. "Yes, if you clean me up and make me feel good, then I will make you feel good with my muzzle, okay?" - "No problem." Lilly said and reached out for the sponge. "No, not with that." Vince smiled. "You have to do it like a big girl." - "What do you mean like a big girl?" Lilly wanted to know. Vince caressed the head of Tracy and with a bit of pressure signaled her to bow down and lick his loins. Reluctantly Tracy extended her tongue and ran it over his sack once licking up a bit of the wet mix.

"Eerw!" made Lilly and wrinkled her nose. Vince was sure he won. "You don't have too. Like I said in a few years when you get into heat you..." - "I will do it." Lilly quickly said. "You don't have to." Tracy mentioned. "Vince, stop with the joke." But Vince, getting over his surprise, touched her shoulder and then turned to Lilly. "I promised you and I will keep my promise. If you manage to clean everything down there and make me feel good I will see you as a big girl and make you feel as good with my muzzle, okay?" - "Pinkie Swear?" Lilly asked and held her paw. Vince locked her little finger with his own and answered: "I swear." "Don't worry. She will most likely stop soon anyway," he whispered to Tracy who looked discontent with his promise. He sat back and spread his legs to allow Lilly full access.

A bit hesitant the little girl approached his lions and first sniffed at it and then did a probing lick. "Erw... it tastes awefull." She complained and directly spit the bit out that was on her tongue. "You can stop any time. In a few years when you are a big girl you might like it but..." - "No, I will do it." Lilly stopped him hastily. Tracy moved a bit away from them and watched this test of bravery for Lilly with mixed feelings showing in her face. She seemed to combine anger, disbelieve, sulking and concern at the same time. If she was angry at Vince for giving in to the whims of Lilly or at Lilly for interrupting them he was not sure. A stronger lick brought his attention back to his balls. That Lilly did not like the taste was clearly visible in her face but she bravely licked over his balls and even gulped the liquid down. Her nose quivered in the strong musk and Vince saw the tip of his member poking out of his sheath.

"Finished." Lilly said proud a few minutes later. She really had managed to lick all the fluid mix away from his legs, balls and the emerging member that now stood hard in front of her face. "Only half way done." Vince said and Lilly looked up. "I said cleaning me, which you did, but also making me feel good, right?" - "How do I make you feel good?" Lilly asked? Vince spotted a bit of cum at the edges of her muzzle and at her nose. He did not really think Lilly would do this much so he was a bit at a loss of ideas for a few seconds. "First put off your nightgown." Lilly complied directly. All shyness she might have to strip naked in front of Vince seemed to be overwritten by the strong excitement and drive to fulfill the bet. "Now crouch on all fours. You will take my dick into your muzzle and lick and suckled it until I feel good, okay? I will do the same with you." Tracy wanted to say something but when Vince looked up she decided against it. Lilly hesitated a bit. "... well if this is too much for you we can..." - "No, I will do it." The girl interrupted him hastily. After going through licking off the disgusting liquid she would not quit now. Vince moved over her and pointed the tip at her muzzle and after a short hesitation she crawled a few inches forward until his member was half in her muzzle and started to suckle lightly. Vince moaned and after a few licks remembered his part of the deal and carefully pulled her tail up. Her snatch was a bit wet from her arousal but else looked pink and innocent tightly closed and not revealing her clit. Vince started with a probing lick that drew a giggle followed by a muffled moan from his loins. He started to wash his tongue over her tail base and tail-hole before licking over her slit again. The moan got a bit louder and in return Lilly suckled more active on his member. He started to slightly move back and forth while he felt his knot slowly forming at his base. Her little muzzle was tight, warm and wet and Vince started to enjoy her suckled and licks more and more. He closed his eyes and licked over her snatch drawing a bit more of the innocent and mild tasting liquid out of her nether lips. Most of the lubrication on it was his saliva that coated all around her precious pearl. Vince felt the clit push through her libido and earned more moans from massaging it with his tongue.

His knot was now fully formed and he pushed a bit more eager. His tip suddenly slipped into her throat and her nose collided with his knot. He heard and felt her gag around his rod and quickly pulled out. But it had felt so awesome that he probed again a minute later. He pulled out fast again but after another minute he pushed into her throat again and this time she did not gag so hard. When he looked back to his loins he saw her head being in one line with her body and pushed into her neck which gave him the perfect opportunity to push in without suffocating her. Moaning he softly pushed in and out until she got used to it and did not gag at all anymore. She also moaned from his tongue that went into action at her pussy again. His pace got a bit faster and his knot was swollen to its maximum size. When Vince pushed his licker through her libido and probed the inside up to her hymen softly she opened her mouth wide in a big moan at the same time he pushed forward. His thick knot pushed her yaw even further open and popped into her muzzle while his dick slipped further into her throat. He heard her gag again but her yaw directly closed locking his knot inside with her teeth softly holding it in. He felt her breath at his hilt and knew that she was at least not suffocating and so he did not try to forcefully rip his knot past her teeth. He explored the inside of her snatch and her gags got weaker until she seemed to have adjusted to his big size. Her lips even closed a bit behind his knot and he felt his knot swim in saliva. Her tongue was pressed down by the knot but the tip still tickled him at his base. Vince started to move the few millimeters that was space between her nose and his belly fur. She did not moan anymore because his member stretched her throat to the limits. He could feel her muscle clench around his member. He felt his climax closing in and started to work extra hard on her clit and slit. A moan next to him made him turn his head and he saw that their show had Tracy aroused as well. She seemed to get off while masturbating and watching her little sister getting fucked into her muzzle hard. "Prepare for the final." He warned Lilly moaning and played with her clit with the paw while licking everything in front of her hymen with his tongue. Lilly was the first one to get her climax. She started to shoot small splashes of clear liquid and from her moan that made her open the yaw wide again his knot slipped out of her muzzle and pulled his member with it. At this moment Vince also lost it and his spunk flooded her muzzle. She was so surprised that he filled her muzzle instantly and she got it in the wrong way. He heard her gulp and cough and felt slashed from her nose against his knot. In her tries to open her yaw wide to make it splash out together with his push it caused his knot to slip into her muzzle again and deep into her throat. While he still heard her sneeze cum at his hilt and she started to pee and relax he spurted with contracting balls all his seed directly into her food canal and her belly. He carefully pulled out when his spurts subsided and he did not get into the danger of making her choke from his cum again. The last weak spurts landed on her tongue before he pulled completely out of the totally exhausted girl's muzzle.

"That was a bit more intense than I planned to, but I guess our promise is completed with this." Her pussy still twitched and the last spurts of pee flooded out of it. He caressed the head of Lilly and helped her to lay down on the side to rest and regain her breath. She breathed heavily through her muzzle. Tracy moaned loud and tried to get off herself by running her paw over her clit. Vince approached her, pushed her on her back and pushed his still hard member into her. After a few pushes and his knot slipping into her snatch she finally came down with her own climax and Vince cuddled with her until his member was flaccid again and slipped out of her snatch. They showered and dried Lilly before cleaning themselves and put on the night gear again. Luckily they moved it far away before their act and they could still wear the same. Then they got back to bed. Lilly already slept and Vince carefully carried her to the room and tugged her tight into her own bed. "I think I went a bit too far." He whispered to Tracy who also looked concerned to her sister. "I hope she is well or your mother will have us." Tracy gave him a soft hit into the stomach. "Leave me out of this. That was totally your idea." Vince pulled her in a hug. "I know, I am sorry Tracy. If I have such a bad idea again please stop me." With a final hug both cubs went to their own bed and soon slept deep and peacefully.

In the morning Lilly had a bad ache in her throat and when Stacy took a look at it she mentioned that it was sore. She suspected a gust of cold air and her shouting the day before. Luckily Lilly kept her promise to not tell Stacy what really happened. The little girl drank a lot of tea and got special mashed food from her mother. Tracy and Vince were extremely kind to her and played with her. They stayed in the house with Lilly and only once every two hours they left her side to have a 'quick bathroom break'. These breaks mostly took thirty minutes and Lilly knew exactly what they were doing but she did not complain. In the evening her pain subsided. The tea had worked its wonders and Vince swore to himself to keep her suffering this day in mind to never have such a bad idea again. Stacy fainted ignorance to the breaks of Vince and Tracy. Vince was sure she also knew what they were doing, even more because the heat of Tracy now filled the whole house, but the adult female seemed to have decided to keep silent and just have an eye on them. The talk between Tracy and her mother was done without Vince and Tracy did not tell him what her mother taught her. She smiled when he asked though. After she said good night to the three of them Vince sneaked into the bed of Tracy and pulled her nightgown up. Tracy did not complain when he pushed his hard member into her slick passage. With silent moans he slowly pounded her until his knot was stuck in her again and his semen pained her already coated womb. Tracy began to purr the same way that Vince loved so much for Mia and he licked over her cheeks before closing his eyes. "Good night Tracy." He whispered and he barely heard her whispered response before drifting off to sleep still tugged deep into her hot snatch.
