One thing that Rob would never admit was that some of the girls actually would meet him outside of class and they would have sex with him on the sly s... no one knew it but Rob and the girl involved. He'd fucked many of the girls under such secret arrangements and he thoroughly enjoyed those side benefits of being their sexual education instructor.One Thursday night, Rob heard a quiet knock at the door and he went down to find three of the girls in his class standing there together."Hi, girls,. He pumped in and out as Krista rolled her hips in circular motions. “Mmm, eh, uhhhhh, eh-eh-eh.” Krista couldn’t help but moan. “Yea, yea, yea,” Jake cooed. “How can I possibly be fucking you. It’s soo...” Krista couldn’t even finish her sentence. “Amazing,” Jake finished for her. “Wrong,” Krista spat as she creamed on Jakes dick again. “It is so wrong. But you fuck so good.” Jake started to pick up speed as he reached his big climax. He leaned over Krista so that his chest was on her. She smiled, and said “Listen, I’ve some chores that need to be done, I was wondering if you could help out?” She quickly added “And I will be paying you this time.”I laughed, “I’ll do the chores and like before you don’t need to pay me.”“Nonsense.” she replied. Then she went on, “Could you come over tomorrow? I need the outside of the windows washed on the second floor. I think my usuals are on holiday and it’s been so hot and dusty ... and then I was wondering if you could change a shower head. She stopped for a few seconds to adjust then pulled all the way out and dropped down until she was completely engulfed on my big thick cock.She just sat there with her eyes not focused and when she got adjusted started fucking me slowly. She said I can’t believe you have such a big beautiful cock, I love it and it feels wonderful.” after she rode me for a while I rolled her over, pushed her legs back against her chest and started fucking her in long strokes. I could see she was getting ready to.
