19th December

Something woke Vince up. It took him a while to shake his sleep off. When he opened his eyes he noticed that it was still dark and most likely the middle of the night. Even though he had been pretty exhausted the last evening he was now awake. A soft mumbling caught his attention and he turned his head to the other side of the room. In the dim light of the moon through the curtains he saw that Tracy stood in front of her bed working on the blanket and mumbling something. Silently Vince got up and moved towards Tracy.

"You are up early." Vince whispered and made Tracy jump and squeak a bit before holding her paws in front of her muzzle to keep silent. "You scared me Vince." She shot at him silently and poked his ribs. "Why are you awake?" Vince repeated his question and at this moment it hit his nose. A strong and fresh scent was coming from the sheets and blanket of Tracy and he saw that she was pulling down the quilt cover and the sheets. "I... erm... promise you won't tell anyone?" she started and from her fiddling Vince noticed that she did not understand what happened. "...the last time this happened I was three." She added embarrassed and Vince realized that she thought she wet the bet. "I will help you." Offered Vince and took the sheets from her. "You should open the window a bit." He advised her. "Meet you in the bath room, okay?" and with this he bounded off while Tracy followed his suggestion and tilted the window to get fresh air into the room.

The moment Vince stepped into the floor he directly started to push his nose into the sheets and sniff at the scent. Tracy went into heat without a doubt. It smelled like Mia at her first day. If Vince had to describe it he would even say her smell was a bit more innocent. The behavior of the girl told Vince that it was most likely her first time and she did not know much about what happened. He felt his member creep out of his sheath from the scent. For the minute until Tracy showed up in the bath room he sniffed at the sheets and his member got fully erect. When the girl stepped through the door and closed it behind herself he let the sheets fall on the ground.

Vince saw a big wet spot at the middle of her nightgown and in the light of the bath room she seemed shyer about her 'accident'. "Don't worry Tracy. I will not tell anyone, okay?" he soothed her. "But actually the kind of 'wetting' you did in your bed is not the same then when you were three." - "What do you mean?" asked the girl surprised but directly pulled her paws up to silence herself. "This is not pee." Continued Vince softly. "You went into heat. You know what a heat is?" Tracy nodded. It seemed that she learned a bit about this already. "Take off the shirt. I will help you." He offered and pulled her nightgown up but she resisted. "This is embarrassing." She whispered but he just caressed her cheeks. "Don't worry. It will feel good." He ensured her. It took half a minute for him to convince her to trust him and he told her to crouch on all fours and raise her tail. She was very hesitant but when he licked over her slick pussy she moaned loud and Vince directly went up and silenced her with his paw. "You need to keep it down or the others will wake up." He reminded her. He picked the nightgown up and urged Tracy to put it into her muzzle. "This will muffle your moans and we can continue." He explained. He saw that Tracy wanted him to continue in her new found pleasure and complied after a short hesitation. She crouched back on all fours and held her tail high and Vince continued to lick her. His tongue parted her soft lips and licked the inside as well. He could feel her hymen intact with the tip of his tongue and like with Mia he went carefully to not make it uncomfortable for her.

Tracy started to breath more heavily through her nose and after a few more minutes Vince felt her lips grip at his tongue and he knew that she was experiencing her first orgasm. He pulled out and put his open muzzle behind her snatch to catch the girl juices she sprayed at him. He knew what would come after it and dodged her urine quickly pulling the sheets to the ground where it would hit so the sheets soaked in her strong smelling water. His member was hard and poked out at the waist band of his pajamas. The tip was slick from his pre and his knot was nearly completely formed. He remembered Mia and how good it felt to slide into her. Here there was another little girl in need and he was about to make her feel good.

Slowly he moved over her. In her orgasm she did not notice that he was above her until he whispered into her ear. Her muffled squeak of surprise was barely noticeable like the moans before. "This felt good right? It will feel even better in a while. Brace yourself because it might hurt a bit at the start but don't worry, only in the beginning. It will feel even better later." He did not wait for her agreement. His member already poked at her wet pussy and he let out a soft moan. He grabbed her hips and slowly shoved himself inside. He felt the pressure on her hymen and she let out a muffled groan. She tried to evade the pain by jumping forward but Vince knew from Mia how to stop her. A soft bit at her neck stopped her in her tracks and while her groan turned into a shriek that was still muffled by the nightgown in her muzzle he felt her barrier give way and his member popping in a few more inches. There was no holding back after this one for him. He started to pick up the pace fast and after a few minutes he pushed himself so deep into her that he poked at her cervix still not being up to the knot. She cried and groaned still not being accustomed to his big intrusion. He disregarded the muffled noises under him and only concentrated to fuck her and trying to get his member into her womb. Her walls were gripping at his member from the pain of the unfamiliar stretching. For Vince this increased the tightness. She felt much tighter than Mia without it already, no surprise taking that she was smaller and younger, but her squeezes stopped his motion every time and drew a strong moan from him. Her cervix refused him entry for over ten minutes that he was pounding her without a break. Finally her muscle relaxed under all the pokes and hits and with a hard slam he smacked with his knot against her lips and felt the tip of his member poke into the backside of her womb. Vince stayed like this for a minute before pushing again. The muffled groans that died down while he just let her adjust to have him in her womb started again and he pushed harder in the attempt to cramp his knot in. He still remembered how hard it had been with Mia at the start and Tracy was even tighter. He was wondering if he would really manage to knot her but he did not miss out on tries.

It was hard for Vince to stop himself from coming but he was set in his mind to get his knot in before allowing himself to fill Tracy for the first time. Her voice seemed to have become a bit hoarse under the muffling gag. She still groaned under him with each push but she seemed to be a bit exhausted from her crying. Her tunnel and pussy relaxed a bit more and Vince felt himself making progress. He already pushed in over a third of his knot and he felt it slipping along the folds slick and wet. A last strong push got him stuck nearly to the thickest part in her folds. He took momentum and pushed hard without pulling back and he felt that every time his knot slipped in a millimeter more. Then he was over the thickest part and her lips slowly closed behind his knot and pulled it deeper into her snatch. When he felt his balls and hilt hitting her wet pussy he moaned loud and let go of her neck. His balls contracted and pushed his seed into the small body under him. Both cubs were sweating a lot and Vince felt her legs starting to give in. He leaned back and pulled her with him into a sitting position. When she hit his lap it pushed his knot a bit deeper and he felt his spurting tip dig into the walls of her womb. A ripple ran through her tunnel and it began to squeeze. Her hoarse voice sounded like she was moaning under her gag and Vince caressed her erect nipples and her belly. He could feel his dick clearly through the skin as well as every spurt. Then her orgasm settled in finally. It seemed to have been postponed by the pain of him trying to knot her but now her body milked the big intruder of every single drop.

"See, it feels good now, right?" he whispered into her ear. "Sorry that it hurt that much before. I promise it will hurt less with each time." He felt his own body trebling in exhaustion. This took him much longer than his first time with Mia but at the same time he felt a strange satisfaction in managing to knot Tracy. "We will do lots and lots of it until your heat ends." Vince whispered. "You will grow to love it." His paws caressed over her naked body. He licked over her face and dried her tears and when he noticed that her breath was a bit ragged he pulled out the shirt from her muzzle to allow her to breathe more freely. "Are you okay, Tracy?" he asked softly while caressing her clit. She was too exhausted to answer but just nodded and he licked her muzzle and nose. Now that he was knotted inside her he took all his time to be tender and affectionate. His balls emptied their last spurts into her womb while she started to moan from his soft touches on her tail base, her clit and her nipples.

The second time he mounted her after half an hour break between parting from her and reuniting again was not easier than the first. Vince put the nightgown into her muzzle again because her voice, now recovered, got loud again. He barely managed to keep his own moans low while he pounded into her tight tunnel and heard her muffled groans. His sperm added to the lubricant of her own heated juice and he slipped in and out at a fast pace. The only difference to before was that her cervix did not completely sealed up and he directly pushed deep into her womb clashing with his knot against her pussy lips. Her libido refused the entry as strong as before and it took him minutes again and a lot of groaning from Tracy until he finally slipped into her snatch again and felt her tight tunnel grip hard around his knot. He spurted into her and let go of her neck that he gripped again with his teeth to prevent her from fleeing forward when he tried to push in his knot. He licked her neck and ears affectionate and started to caress her belly, teats and clit. He was nearly done with his climax when she finally came around with her orgasm and started to grip and milk his member.

Vince moved into a sitting position again with her pinned on his member and locked by the knot on top of his lap. He stimulated her clit and nipples and prolonged her orgasm so long that his knot started to swell from her clenching tunnel before it was slipping out. He pulled the shirt out of her muzzle again and her moans were weak enough to not alarm anyone in the house. He pushed up with his hip and made her bounce slightly in his lap causing small movements of his rod and knot in her snatch. Vince caressed his knot and rod through her skin which added a bit to his arousal. "You are so incredible tight." He moaned into her ear before he felt his balls beginning to contract again. The pressure in her womb went up with each of his spurts and he felt her belly slightly bulge under his paws when his last splash entered her. She hung in his arms on his lap. All the energy left her from these two rounds in a row. She had moaned all the time and her tunnel had twitched stronger and weaker every now and then. He let her rest on his lap while his knot slowly shrank down and he felt the mix of their juices run over his hilt and balls on the ground.

Two more rounds of the same circle exhausted both of them quite intensely and Vince jumped under the shower with Tracy and helped her to clean herself while she got very sleepy. "This will be our secret." He whispered and kissed her muzzle after they dried up. They cleaned the bath room and put the sheets into the washing machine. Tracy knew how to set it and where to put the soap in and when it started to run they sneaked out into the floor. Both Vince and Tracy had to put on new night gear and then Tracy slipped back into her bed with new sheets. Vince bent down to her and kissed her on the muzzle. "Good night Tracy." He whispered and then crawled into his own bed. With nearly three hours of mating both of them had no problems with falling asleep directly.

This morning Lilly tried to get them out of the bed without any success. Both of them said they were too tired and wanted to sleep a few more hours and after twenty minutes Lilly gave up. Vince could hear her talk to Sarah downstairs before he rolled around and fell asleep again.

'We are out with the Purringtons. We expect to be back at five. There is food in the fridge. I hope you two are fit and well. Stacy'

This letter lay on the table when Vince went down ahead of Tracy. She followed a few minutes after him. Both of them still had their night gear on. "Looks like we overslept." Tracy yawned and got herself some cereals. "Yes, now we got the house to ourselves for a few hours." Vince replied and took the cereals after Tracy finished filling her bowl. "How are you feeling?" asked Vince and smelled her heat scent getting stronger again. Tracy was a bit shy which was something new for her. "It is wet again and burns a bit. Also there is such a weird itch." She tried to explain her feelings. "Come and sit here." Vince requested and pointed at his lap. Tracy was hesitant at first but then climbed on top of his lap and started to eat from the bowl that she placed next to his. Vince pulled her nightgown up and caressed her tights with his paws. She giggled because it tickled but when he scratched over her clit she moaned loud. "Do that again. This felt good." She mentioned and Vince complied with a satisfied grin. At first Tracy still ate her cereals but after five minutes she leaned back against Vince and moaned while snuggling her back against his chest. His pants were wet from her juices that leaked strongly and he felt his member getting hard from the scent. Every now and then he pulled his paw up and licked it clean taking in the wonderful taste of Tracy. When she came down with a small climax he could not control himself anymore. He pulled the waistband of his pajama pants down and let his member jump up. The knot already formed. Then he guided it into her snatch and pushed her down. She moaned strongly and his half formed knot slipped in directly. With small vibrating movements he move inside her while his knot got thicker and finally locked himself inside her without him having to push it in by force. It was just filling her from the inside until it was complete. Vince moaned while he spurted inside her and the climax of Tracy took off for a big one milking his dick like her womb was dehydrating. "You started to enjoy it, right?" he asked while he made her moan with another small push. "It does not hurt so much anymore and feels weird but good." She tried to explain under her moans.

For Vince the day was like the last day of Mia's heat. He took Tracy even more often than he did Mia. One of the reasons was that Mia had controlled him the last time but here he was the one commanding Tracy what to do and the poor girl was so captured by her first heat that she just followed his directions. Also her exhaustion added in every now and then and he waited for her to regain her energy back. Most of the time he stayed deep in her womb feeling his own spunk swim around his tip until he felt her fatigue fade. Vince made sure to clean every room they practiced their mating before they left and open the windows to erase the scent. When Lilly and Stacy came back in the evening Vince and Tracy were in the bath room and he was knotted into her while they faced each other and he had pressed her against the wall. Luckily for them he slipped free just half a minute later and they quickly cleaned the room and themselves and when Lilly came upstairs ten minutes later they already were in their clothes and played in their room. Vince felt his member still erect pressing hard against his pants and he saw that Tracy also felt a bit uncomfortable. They had not completely dried their fur off because they did not have the time and they also were not able to clean her snatch. Vince was sure that her slip was soaked in their juices right now under her pants. This imagination did not help him much to get his penis to retreat. From Lilly's explanation she helped Stacy with some groceries in the kitchen and this was why she took so long. This also was in favor of the older kids because they would probably not have managed to get out of the bath if Lilly would have been faster.

At dinner Stacy directly noticed the scent of Tracy and scanned the older kids with a gaze. Vince was sure that she counted one and one together and knew what they did all day. She was the one who introduced him to this after all. In front of Lilly she did not say anything though and just brought up other topics. Before going to bed she just mentioned it with one sentence to Vince when they passed at the bathroom door when he went to bed after brushing his teeth. "I hope you were gentle." She just mentioned and Vince looked to the ground embarrassed. He did not tell her that he totally lost control and pounded Tracy and also not that she cried a lot at first. Stacy did not press the issue but let him go to bed. She kissed all the kids good night and whispered with Tracy. Vince heard a bit and got as much that Stacy said she wanted to talk with Tracy the next day. Probably she wanted to tell her about the heat herself but Vince just hoped that Tracy would still be willing to share the intimacy tomorrow. In this night he still dreamed of Mia but Tracy also appeared in his dreams. While the younger girl was in heat Vince could not tell who he loved more. At the moment he felt deeper for Tracy at least but if this was love, instinct or just horniness the boy could not tell.
