Believe me, my masturbation was never that good. That was one of my best faps ever. But later I felt it was wrong and I thought of never doing it.Now ... months passed by and one day I was walking through the living room I suddenly looked into the bedroom, I saw my mom lifted her nighty up to wear panty. As I was seeing from her back I could see her 38 size ass that was the best thing I ever saw her ass was very fair, big, spongy and between the two buttocks it was bit dark.Seeing this my dick. .....Seems I missed the first two blasts, landing on the floor beside the bowl while I still had my eyes closed......oops.And yes, A. Sue found it. The next morning as I was making my way to the kitchen, I glanced into the open toilet/bathroom door and saw A. Sue down on hands and knees, cleaning my mess. Sensing me behind her, she swung around and propped with her arms on one knee, saying, “Hi honey, I’m not sure what got spilt here, but it’s terribly gooey...””Give me a moment and I’ll get. ” She smiled at him, and Mark nodded. “I'll get us some refreshing drinks then,” he said. Mark returned a few minutes later with a pitcher of lemonade with raspberries and blueberries that he made from scratch. He was still nude, carrying two glasses in his other hand, and he saw that Erica had set herself up on a deck chair, next to his and at a slight angle. She was lying on her back, her book and toy on the low table between the two chairs. Mark poured lemonade into both glasses, handed one. I told her Anna invited me and she let me in. As I was in Anna saw me and walk toward me and gave me a hug. At this stage the girls are pretty drunk but they still quite active. Anna pour me a drink and we took a sit in the sofa, she sat next to me and while we were chatting away with the other girls Anna hand was roaming my leg and rub up my cock a few time. My hand was behind her rubbing her ass and notice she was not wearing any pantie. After about an hour of this Anna told me to follow her.
