Summer Heat - Chapter 48: Substitute

July hit and rang in the end of the term. The last of the exams had been written and graded and were sent to the school ministry for an after check. The grades were, like Zen expected, very good. All girls soaked in the information that he or Mara taught them. Now, that normal classes came to an end, they spend a lot of time together with the cubs and took long baths in the sun or the water. Samantha already taught her cubs how to swim. With half a year they were very young for that, but as alligators they were already in their element and darted through the water nearly as fast as their mother. Despite Zen's wish, the next one to get into heat was not one of the young girls, but Bertha. The otter entered her heat at the start of July and just like the girls she did not wait to approach Zen about it. The adult women also enjoyed the attention of the well sex trained wolf. In their heat, they were actively searching for his company, even though they had more experience than the girls and knew how to endure it much better. With Zen around there was nothing to endure though. Even without the rule, Bertha would not have skipped the opportunity to have her snatch stretched like at the time she conceived her son, who was swimming with Samantha and her cubs. The alligator mother watched over all the cubs in the water together with Sandy. Paula was in her laboratory, doing some experiments, like most of the time.

Zen was laying on a deckchair when Bertha approached him. She directly climbed on his chest with her heat swollen mound pushing against his nose and witnessed his member directly exiting his pouch when he took in the intoxicating smell of the female. She was much smaller than the wolf boy and therefore he had to push his head a bit forward to lick her heated snatch while she moaned and opened wide to suckle on his member. She had done this many times before and did not even gag when he maxed out and she took his member deep into her throat until his growing knot pushed softly against her nose. His tongue was already eating out her honey pot and made her squirm and emit muffled moans around his member. Her tongue was nearly as active as his, slurping around the meaty slick rod in her muzzle, that had its top pushed past her throat already. It was hard to breath with his thick member in her throat but she had learned how to keep up with it in her time here. Zen had trained all the girls in giving head to him and deepthroat, but he never forced them but only asked them to. Bertha just went with the flow and learned alongside with her daughter. The otter woman opened her yaw as wide as possible to allow the heavy full extended knot to slip past her lips. It did not hurt her anymore to stretch her muzzle this much but it still was a bit hard to open wide enough. The knot popped in with a small rocking and Zen's tongue scratched her g-point, making Bertha climax at the spot together with the twitching member that spilled gush after gush of spunk down her food channel into her stomach while she squirted her own flood over Zen's head and inside his open mouth. While she waited for his knot to shrink a bit and have it easier to slip it out, she shivered under the continuing licks of Zen. He paid special attention to her snatch, her tail hole, the tail base and he also licked over the erect dugs at her stomach. She could feel the arousal building up again and finally she managed to pop his knot to moan loud. "You really know how to pleasure a woman in heat." She huffed and her insides already prepared for another climax. Zen just grinned as a response and plunged his tongue deep into her tunnel, which made her moan and climax on the spot again. Some of the girls, under them her own daughter, watched the game between Zen and Bertha, while others were more into sunbathing or swimming or playing on the meadow. Bertha took a while to calm down after her second climax, while she serviced Zen another time by licking over his still thick knot and his long shaft making him spurt his spunk over her head this time. After his spurts subsided, she revived his member with a few more licks, before she turned around on his chest and faced him with her cum coated head. "You are cute like that." Zen chuckled and kissed her on the muzzle. Bertha returned the adult kiss and she felt young again, just like all the girls around her. In his embrace, she felt like her age did not matter and she was like an adolescent again and forgot for a moment that she was older than Zen. He was so dominant and at the same time caring, that it was no problem for the otter woman to return to being a girl and just let him have his way with her. Zen poked at her folds with the tip of his slick member, making the heat driven female quiver in anticipation. Then he finally pushed in and she felt like she melted. From the moan of Zen, he it seemed that he felt the same way and he pulled the otter into a kiss while he established a slow but powerful rhythm and pushed his member all the way past her cervix, resting his knot against her folds for a few seconds, before he pulled back so far that he nearly left her tunnel. She moaned and felt his full length sliding in and out while his paws caressed around her tail base and he even slipped a finger inside her tail hole and stimulated her in addition. Her moans were muffled by a deep kiss and they caressed each other's tongues. Bertha closed her eyes and felt her tunnel already twitch slightly again in the beginning of her next climax. When she was in heat this all felt so much better and she was stimulated so fast. She also felt the thick rod inside her throb and knew that Zen was holding back hard until he finally pushed in extra strong and popped his knot into his tight female with a short feeling of pain for her but the wave of pleasure directly washed over her, making her climax on the spot when his hot spunk hit her womb for the first time. Both forgot that all the others were watching and just mated like that for hours until they were exhausted from their many orgasms. Zen carried Bertha to his room and she fell asleep in his embrace while his throbbing member pushed the last load inside her sacred chamber.

"I am pleased with the cubs I have, already." Bertha said. They had just woken up and after one round of mating she asked Zen if he would allow her to take the pink pill to prevent a pregnancy. Zen did not hesitate. Not only did he in this moment remember that the increasing number of cubs was a problem he saw as well but he also did not want to force his females to get pregnant if they did not want to. "Whatever you want my dear." He said with a smile and went to the desk to fetch the small pink pill. He looked at the other tube and while he was at it also fetched a blue pill. "Here you are. I guess this ends our fun for now." He said and gave the pink pill to Bertha. The woman smiled and took the pill with some water. "It was very exciting, but I have my hands full with the two cubs I have." She replied. "Not that I would not want another cute cub with you some time in the future. Just not now." And Zen pulled her into a kiss, his hard member pressing against her erect dugs. "Don't worry. Come to me whenever you feel like having another cub." He replied and they shared a kiss while Zen smeared pre over the belly of Bertha and her snatch was still leaking his spunk. Zen knew that it would be cruel to mate with Bertha now, because the pink pill still prevented her to orgasm and it would be a torture for the woman. But he still longed for a fuck with the otter and on this demand, he had picked up the blue pill. He asked Bertha to wait for him in the room, and take a shower if she wanted, and went to get her daughter Tammy. The ten years old otter listened to his request and was directly eager to step in for her mother. It was the first time Zen had her take the blue pill and after hearing about the effect from others she had already wanted to try out to experience a heat for a day instead of waiting another two years or so to get into heat naturally. While she walked back to the room, she swallowed the pill and the effect directly kicked in and made her moan. At the time, she entered the room with Zen, she was already leaking hot juices and Zen put her on the bed to eat her out and make her moan in a frenzy. The feeling was much more than Tammy had expected from the description of others. She moaned loud and her eyes closed half in the intoxicating stimulation while Zen worked her nipples and snatch good with his tongue, drawing her near to her first climax fast. Before she reached her first orgasm, he moved over her and she felt his big member enter her tiny snatch. She was extremely tight for him but even without the faux heat she had stretched strongly and with the wet and heated mound now she split open without problem, moaning in a half daze already when he pushed in to his knot. His tip pierced her cervix without problem, coming to a halt half in her womb when his knot hit her drenched lips. Zen only rested like this for a few seconds, before he pulled all the way out, just like with her mother. Bertha came into the room, out of the showers, when her daughter emitted a high-pitched squeal in her shattering orgasm and Zen still pumped in and out for three more times before he forced his knot into the moaning girl under him, making her groan for just a second, before his hot juices that gushed into the petit girl made her whimper in pleasure and her belly bulge fast. This was just the start of the day though. With the heat scent of Bertha and the scent of the faux heat of Tammy, he did not leave much time to rest for the young otter. Whenever his knot shrank enough to him to pull it out with a pop, he just used this to start and move again. The girl entered a spiraling orgasm that only died down for a short time when he rested and waited for his knot to shrink. She had given herself to the pleasure of a love daze a long time ago and sometimes dropped out exhausted. Zen patiently waited at these times, stuck within her to the knot, until the girl woke up and then he directly continued the mating. Even though some of the spunk spilled out when he mated her, the young otter girl bulged so strong, that even standing on all fours did not prevent he belly to touch the bed sheets under her. "I cannot wait, until you are ready to get pregnant for real." He whispered while he let the girl rest with his knot stuck inside her and his paws caressing over her large belly. "You are pretty cute with this big belly." He kissed her cheeks and she gave him a weak smile.

Bertha stayed with them all the time to make sure, that Zen was not overdoing it. He had enough control over himself though for the otter mother to not step in and stop him. She joined in by licking him and her daughter and make them come a last time while they lay exhausted on the bed, Tammy on the belly of Zen with a big bulge at the middle of her body. "Too bad she is not an early bloom like my sister." Zen mumbled before he closed his eyes and followed Tammy into sleep. Bertha laid down next to them and put her arm over the chest of her daughter. With her hand, she caressed over the big belly for a while, checking if the pressure was too much, but it seemed that Zen stopped just at the limit.
