Pete rolled her over to her back saying, “I might as well be in control now, since your hymen is already gone.” She agreed. He started a rhythm, sliding his cock fully in and out of her vagina, further and stronger with each stroke. Eventually, he was pounding her at a pretty good pace, and she was moaning and squealing under him. He found that her panties were rubbing the side of his cock with each thrust, so he disengaged and pulled off her skirt and panties and his boxers before reinserting his cock back into her pussy. She barely noticed the interruption.
Pete continued at a good pace until he felt the seed start rising in his balls. Then, he used his thumb to rub her clitoris until she was starting to climax right along with him. As her vaginal walls started milking him, he started pumping load after load of his seed deep into her womb. Who knows how long it lasted? Time stood still for both of them as they were swallowed up in waves of pleasure.
Pete finally collapsed, rolling slightly to the side. She rolled with him, keeping his cock buried deep in her pussy. He could still feel small pulses of semen being pumped out of his cock and into her vagina. They kissed some more, but then exhaustion soon caught up with both of them, and they fell asleep.
They may have been asleep for a couple of hours when they both woke up. Beatrice’s mom wasn’t yet home, but she would be soon, so they got dressed and he got ready to leave. They arranged to meet again the next Sunday, and he left. This would become a regular routine for Pete, Thursdays for Shirley and Sundays for Beatrice.
Pete found this to be quite beneficial, not just for the girls, but also for him. By teaching these concepts, he not only got sexual benefits, but also kept the concepts fresh in his own mind. Time is the enemy of memory, so by keeping these things fresh, he stayed current as well. This would help him later on when he continued his education at university and when he became an engineer.
The next Sunday, he and Beatrice changed the time slot to start at 10 AM, so they would have more time before her mother arrived. They still only studied for two to three hours, but it gave them more time to play afterwards. Unfortunately, she was on her period, so she gave him a BJ in lieu of sex. It wasn’t all that good, but she tried. He ate her to several orgasms in return, which she absolutely loved.
When she realized that he was hard again, she offered to get him off again. He asked how she wanted to do that. She replied that she had heard of anal, and would be willing to try. Since her pussy wasn’t available, he asked her to find some lube. She got some Vaseline, and he had her apply it liberally to both his cock and inside of her rectum. She tried to follow his instructions, but after applying it to his cock, she asked him to apply it to her butt. He complied.
Pete lubed up his finger and slowly pressed it into her bottom. At first, it didn’t look like her anus would accept even one finger, but then it slipped in. He went back to the jar for more lube, and pushed the lube deep into her rectum. After working the lube around inside her butt with his finger for a while, he added a second finger, which caused her to strain again the intrusion, but she was still willing to continue.
After several minutes working two fingers in and out of her bottom, and loading her rectum even more with Vaseline, Pete lined his cock up with Beatrice’s anus, and then slowly pushed it in. She gasped when his big cockhead penetrated her sphincter, but then his cock smoothly penetrated deep into her without further pain. He rested for a few seconds, and then started thrusting and withdrawing from her butt. He reached around to fondle her clit as he pumped his cock in and out of her backdoor, and soon she was pushing back against him with increasing passion.
When Beatrice started cumming, Pete couldn’t hold out any longer. His balls pumped spurt after spurt of his seed into her rear as she climaxed beneath him. “Nice,” was all she had to say when they both collapsed on her bed. They were soon asleep, but the first week had taught them a lesson, and the alarm gave them plenty of time to clean up before Beatrice’s mom came home. Pete never did meet her mother.
Beatrice joined Pete and Shirley for lunch every day at school, and they soon became a fixture. He was surprised when it became obvious that both girls knew about the arrangements he had with the other, but then he should have realized that girlfriends tell each other everything. It did make for some awkward moments when one of them said something blatantly sexual in front of the other, and he asked them not to talk about these things in front of him. They both chuckled, but then complied.
Of course, Pete didn’t allow his social life to end there, and he was constantly on the lookout for cute girls around the campus and in the surrounding towns, but Shirley and Beatrice were almost always in need of tutoring while Pete attended UC Rockville. He often wondered what happened to them after he moved on to university.
