The nurse came over and took a look."Are they all female sperm, or are there male too?"Dr. Betzler started. "That's a very good question. I don't know... My microscope is not strong enough to tell that. I'll need to take it to a more powerful microscope, probably at the university."About a half hour later, Melanie, Lisa's mother arrived.The nurse escorted Lisa back to the exam room.Dr. Betzler said, "Wait in there while I explain your condition to her. It will be less of a shock when she sees. Once letting go I undid her pants and pulled them down leaving her standing in her silky blue g string. I then made her lay down over my lap and on the bed and while massage her bum cheeks I asked do you like being spanked. "Yes I do Master."

"Can my slut handle more. Then she came over and layed with me. now i was 16 and she was 19. she was laying in front of me with my dick rock hard right next to her pussy. i was just laying there with my arm around her. she looked at me then we started to kiss.. my uncle looked up right after we stopped and then went back to bed. so to make it safe we went into my bedroom.We were laying with eachother kissing and rubbing eachother. i took her shirt off and then started feeling those nice little tits. her nipples were. A quick check-in, and we were on the flight. We passed our time playing cards, watching a movie, and in the end, just talking. Carol wasn't a great aircraft person, and after five hours, was gripping my hand tightly.And at that time, I decided to come clean about what I had done."Listen Carol," I turned to face her, "there's something you should know. Before asking Sheryl to come with me, I had already upgraded the accommodation to another one." So...if it's an upgrade it's better, right?" she.
