Summer Heat - Chapter 39: Another Failure

The next week was hard for Zen, because at the morning after Minna gave birth they looked at the diaper he put on and he had been scolded for the bad work from Paula and Mara. Instead of praising him to try hard they blamed him for not being able to put on the diapers correctly after so many cubs that he already had and they decided that it was time for him to learn how to put them on. Every evening Zen was exhausted, because the girls all decided together that Zen would have to put on all diapers until he could do it as good as them. Because the number of cubs was already 19, this was nearly non-stop work for him. He always had one of the older girls, who know very well how to do it, at his side to give him instructions when he went wrong but it took him three days to finally get by without a baby pin and another two days until the diapers even looked nice. On top of having to do the diapers he also had to hold classes, even if Mara took over most of the sessions now. At night, he just fell into his mattress exhausted and did not even notice the girls piling around him. He slept a few hours, until he was woken up by one of the girls because the diapers of one of the cubs needed to be changed. Zen was happy when they let him off the hook after the week and shared the duty again. Zen even dreamed of folding and knotting the cloth and it took him two more days until he gained back his old energy and was able to sleep through the night. By now he understood the hard job if Paula and Lena, who usually took care of the cubs all the time with temporary help of the other girls. Well, Minna and Dott also helped them since they joined the school, but even for four it was a hard job and they were happy whenever some else assisted them. In the past, Zen had helped them, however they always had to watch him putting on the diapers, because he had been very clumsy at that. Now he really was a help for them and he even enjoyed these tasks because it was something he could do for his beloved cubs and girls.

The end of October was getting closer, when Paula one day asked Zen to join her at the cottage in the evening to talk about something. Before he asked about her reason for this meeting, that she wanted to have without anyone else, he greeted her with an affectionate kiss and he even stimulated her a bit with his fingers. "I thought you went into heat again." He said a bit disappointed to find that she got wet, but that there was no sweet scent of heat. "I think you would have loved that, right?" she asked and giggled when he pulled her into a deep kiss. "But it is related to heat in some way." She continued, while she loosened his arms around her and moved to the table on the other side of the room. She grabbed a vial with a blueish liquid inside. "I just completed a new proto type of the liquid for younger girls. It is a milder version and should not bring any danger or side effects for the girls, but I am not sure if it works the same way." She placed the vial into Zen's hands. "I thought, that you could test it with whichever girl gets into heat next." Zen looked at the vial. "You said that it would take a few years after they give birth, right?" he asked. "So, this means the next girl would most likely be Olga, taking, that she is the oldest of those who still did not have a cub." He looked up and Paula smiled. "But you know, that I would not want to prevent her having a cub, right? At the first heat, I always intend to breed them and get them to bear my cub, if it fits with the time." He looked at the vial again. "I know, that she would go into heat again after a month, but this would be risky. This month is the last one where the cub will be born before the end of the school year." "I think ..." said Paula, "... that Olga still has a few months for her heat and there will be others before her. It could be that Mara and Sierah get into heat again before her. How about testing it, when they go into heat. It is not as much of a problem for the timing for them, right?" Zen pondered. "Okay, well then I leave it to you. Can you talk to them and ask if they agree to test the liquid? And tell them that it is only for testing. I will make sure that they have another cub inside them with the following heat, if it does work. Just like with Gilla. I would not pass a chance of having another cub with my cute sister and my best friend." He grinned and Paula chuckled again. "I already was certain that you would plan to impregnate them again." She replied and after she put away the vial, she sat down on his lap and kissed him while his half erect member softly brushed over her moist folds. Even without heat, both of them enjoyed the hour of slow but deep mating. Zen even allowed the smaller Beaver to take over the control after his first climax and they only stopped, when one of the sleeping cubs woke up and needed their attention.

Paula was right and the heat of Sierah came faster than she expected. Only three days later Zen was woken up in the middle of the night by the soft touch of his sister. He carefully crawled out of the embrace of Bea and Mimi, who had managed to get the place next to him this night, and his nose twitched already smelling the start of her heat. In the past, Zen would have just pounded his sister at the spot, but he guided her away from the room where everyone was sleeping and into his own bedroom, which he only used rarely for sleeping these days. The vial was on the table and Zen handed it to Sierah. None of them spoke a word, but they understood each other without words. Zen had two intensions in changing the location. On the one hand, he did not want to wake up all the cubs, that were sleeping in the big room, on the other hand he wanted some time alone with his sister. She moaned when he laid her on the bed and started to lick her snatch. This took Zen back to the moment over two years ago, when she woke him up for her first heat. This was her second heat and this time, Zen knew what he was doing and what the consequences would be. He took his time, just like at the first time he mated his sister. His tongue explored her snatch, her legs and her dugs intensely and the girl soon could so nothing more than huff, moan and clench her paws into the sheets under her back. Zen got much more skilled in the last years and even though Sierah knew his skills from the countless muzzle jobs or mating sessions she had with him off season, it was different during her heat. It felt much better than anything before. It also was no comparison to the first time he took her. Back then he had been very inexperienced. He had tried out things, that he only read about before and that they ended up mating was more of an accident than a planned action. Sierah remembered that it hurt so much at the start, but now it would not hurt, she knew that. She took his knot in without pain nowadays even without being in heat and her snatch and tunnel burned in a fire that longed for his hard organ. Even his tongue, that he plunged into her as far as he could, already felt heavenly and she cried out in orgasm. Both did not notice, that the door was silently opened and two dark shadows slipped into the room before closing the door again. The shadows sat on the floor in the middle of the room and their paws went between their legs while they watched Zen giving Sierah the most intense muzzle job of her life. Zen did not stop before the girl achieved two orgasms, even though his member and knot were rock hard and hurt from holding back his instincts. Finally, he was not able to hold back anymore. He rolled his sister on her belly and she already raised her hunches and pushed her tail up into the air. The intoxicating scent of her heat filled the room and Zen groaned from the smell alone. Pre was already dripping down his tip and built a small puddle in the floor, before he moved over his sister and smeared the sticky liquid into the fur and skin around her pussy. It took him three tries, before his eager thrusts sent his member into the young she-wolf beneath him. He speared through her love tunnel and both moaned in unison. Zen was long past his limits of holding back and his hips went on auto pilot and hammered into the helpless moaning and huffing girl, that already was very exhausted from her earlier orgasms. It did not take Zen long before he pushed extra strong and sent his knot into her snatch. His member exploded inside her and his balls contracted and pushed strong spurts of the lifegiving seed through the channel and into her waiting potential fertile womb. None of them knew if the liquid, that Sierah took before they started, would work but none of them cared about it. The instinct of Zen was to breed his sister and place another cub inside her. Sierah achieved another orgasm from the spurts into her sensitive insides and both joined into a howl, that they muffled a bit with the pillows and cover of the bed to make sure not to wake up the others. When Zen rested upon the shivering and sweating body of Sierah, he suddenly felt two tongues licking his still twitching balls. He looked back and saw the smile of Zina and Tara. The scent of their arousal was not able to break through the heavy heat scent of Sierah, but Zen saw, that the fingers of them, that now caressed the leg of him and Sierah, were drenched from their own liquids. He felt the legs of Sierah giving in to the exhaustion and rolled on the side with her until he was laying on his back with Sierah on top of him, still knotted. She had her eyes closed and moaned from the tongues that also licked over her clit and dugs now. Tara crawled up on top of Sierah and rubbed her own hard dugs against the teats of the white wolf girl. Zen wrapped his arms around both of the girls and his paws started to dig into the snatch of Tara, while he still felt the tongue of Zina stimulate them and make the two white wolfs moan. Zina continued until she drew out a second strong orgasm from Zen, who was still knotted deep inside his sister. This triggered a last peek of the spiraling orgasm of his sister, who had not been able to calm down with the knot inside her and the tongue on her clit as well as the kiss of Tara, and then she fainted from the exhaustion. Zen pushed his paw between the wolf girls and felt that Sierah was bulged out strongly and he caressed her belly, while the back of his paw scratched over the dugs and belly of Tara, who moaned as well. He also felt a bit tired from not sleeping too long this night and leaned back. Zira crawled up to the bed and cuddled up next to him. Zen used his other paw to stimulate the panther girl as well and while he closed his eyes he had his fingers deep in the snatch of the two black-furred girls until he first felt Tara tighten up and heard her moan from the small orgasm she achieved and then Zina followed a few minutes later. He shared a deep kiss with Tara and Zina before he had Tara lay down on his other side and pull the cover over all four of them. Sierah was already sleeping satisfied. Her heat was still at the beginning and therefore it was not strong enough to wake her up again this night. When the sun was peeking through the curtains and Zen woke up, the three girls still slept and he still felt his half erect penis snuggled inside his sister with all the liquid spilled over his balls and his fingers were also still in the wet and soft snatches of the girls next to him, where they were when he fell asleep. The scent of his sister made him grow harder after a few minutes and soon he was softly pushing into her and she started to wake up with low moans. At the same time he tried to stimulate the girls next to him, but his knot formed inside of Sierah and both of the white wolfs achieved their orgasm, before the girls next to them were close to theirs. They were very moist, but they did not wake up to their own orgasming body, but to the howl of the siblings next to them in their climax.

With the increasing heat scent of Sierah, Zen returned to his old ravage ways in mating and with all the rest he had in the last weeks, he put Sierah up to a battle for endurance. She was not far behind him with her endurance and a few days later even Mara got into heat and joined them. This was much to the disagreement of Zira and Tara, who backed off, after the kitten in heat joined the siblings. They stayed in Zen's room most of the time. Only for the meals or for some outside fun in the sun they left the room and the ways in the school returned a bit to the old atmosphere of arousal and pleasure. When Zen tired out Mara and Sierah and still had some energy left, he took one of the other girls. Especially Tara and Zina were always happy to have him mount them, but they were not the only ones, who presented for him and used the time when the white she-wolf and the lioness slept, to get a bit pleasure themselves. They were also heavily affected by the heat. They did not pay much attention to put the cubs away when Zen was mating outside. For them it was normal and nothing the cubs should not be allowed to see, however they also did not force them to watch and usually the cubs only looked at this new game, that they saw before but never this intense, for a few minutes, before they continued with their own games. They were much too young to understand or show interest in the actions of their father with the females in heat. The heat of Sierah declined first and a few days later, Mara also stopped to send out the heavy scent and drip from hot juices. Both of them were very sore from the ravage of Zen. He cooled down with all the other girls and in their sexual classes, they mated more than in the months before, but eventually, Zen snapped out of it and his mind was not dominated from mating anymore. The liquid did not show the result that Paula hoped for. It seemed that the mild version was too soft to prevent the pregnancy, because after some blood tests she confirmed that both Mara and Sierah were pregnant again, a fact that was welcomed by Zen, even though it meant that Paula would have to start anew with her medicine. The only good result of the test was, that none of them showed any side effects and Paula was set to re-calculate the formula to create a new medicine that would be usable for the girls. For now the they all congratulated Mara and Sierah, who also seemed to not be too unhappy about the result. Mara only mentioned, that she would have preferred if the medicine would have worked, because this would have been a success for Paula, but in the end she was happy to be pregnant and like every time before, after Zen impregnated one of the girls, he showed extra attention and affection towards those two in the next weeks.
