For Christmas vacation our senior year, Cindy's parents were going to Florida. I invited her to spend the holidays with my mother and I. She accepte... my invitation and came home with me after our last class. Mom had made space for her in Janet's room. I StartedTo panic. Cindy would be spending two weeks in "My" room; I didn't have time to hide any pictures, Janet's diary, nothing was hidden.Jim had made plans to ask Cindy to marry him, on Christmas Morning. I knew I would have to come. He was researching his family tree and wanted to find if he had any relatives here.Ed was disappointed when Jen excused herself and started back to her back door. Ed just stood there, reflecting on his good luck to move next door to this gorgeous nymph and watching the exaggerated roll of her beautiful ass as she walked.By the time Jen went back into the house, the tingling in her body had changed to outright lust.

I never thought she would let me take the pics, but I offered anyway. She agreed to let me take pics of her ass with her thong sticking out, and another pic with her pants halfway down and her thong out as well. Luckily there. Aaahhhhhh"I didn't say anything. I kept grinding up against her pussy then I started to really rod her, going in and out, hitting bottom rising back.When I cummed, I kept my dick pressed deep in her so she could feel my seed hitting her when it shot.Mom lifted her legs up, this time putting her knees to my shoulders so I was smashed straight up against her pussy. Nothing blocking me, no legs to maneuver around. It was straight pussy, wide open. I remained hard as she pushed and rolled, keeping.
