This position really got Katie going, too, probably because of the angle I was entering her and the pressure on her clit from having most of her weigh... pushing our pubic bones together. Every thrust seemed to cause another orgasm in her, and I had to keep thrusting to keep her up against the wall and not drop her. The effort of holding her up while fucking also made it more difficult for me to come. The fact that I lasted longer just resulted in more orgasms for Katie.I think she started to. Campbell called out my name. "Jimmy, would you please stay after class for a minute, I need to talk with you," she said."Um, okay," I said, sitting back down in my seat. We waited until the rest of the class had filed out of the room and then she came over to sit in the seat next to mine."So, Jimmy, what is the problem with you and this class? Don't you like it?" she asked."I-I don't have a problem, Ms. Campbell," I answered."You certainly do. You are doing poorly with your assignments… you. I said, "The first thing I want is next Saturday to be my day. And the first part of the deal is that any time you're in a skirt, you can't wear any undies." Tara laughed, she knew she never wore undies anyway when she was in a skirt, so that was any easy request.Saturday morning came around and the first thing I did when I woke up was remind Tara that today was my day, and she couldn't say No to anything I wanted.She agreed. Then, she reminded me she was meeting one of the girls at 3PM to play. As I sank to full-depth Lisa reached beneath herself and started rubbing her clit. I began long slow movements in her arse, slowly building the pace as her orgasm approached. She was gasping and panting with pleasure and suddenly began shaking and screamed “I’m coming “arching her back and almost rolling over. I was about to pull-out but she stopped me “I want you to come in my arse babe – so keep fucking me” I did as I was asked – her arse felt wonderful. Normally if I have a good drink I last.
