After the normal check list of questions for me she asked if I might have a little extra time to participate in a research study as I was in the targe... age group. The study was to see if a prostate massage might be a better way to provide erections than medicine, you know the little blue pill (there must have been an entry in the notes from before about my reaction). After qualifying me she did explain the methodology that was to be used. First, she would provide prostate exam and continue. Nibbling, biting, teasing. Her tits were magnificent. She cuddled my head forcing me to take more of her tits into my mouth. I had to have more. I trailed my kisses down her stomach and lowered her panties as I went. Her bush was wet and shiny. I rubbed her mound and licked her lips. “Oh God, Oh Yes” she panted. My fingers spread her lips and I slid one than two fingers inside her. In and out, back and forth. I flicked her clit with my tongue and she moaned louder. My fingers reached up inside. “Is Tony watching?” Amy asked, suddenly. “Don't worry about it” my dad said sternly as it became his turn to get aggressive as he grabbed a fistful of Amy's hair and began to hump Amy's face. I looked up as I continued to pound my mom's pussy as her orgasm started to subside. Yes, Tony was watching alright. And he looked pissed. The sudden silence from Kelly and I allowed me to hear another sound."GWAH! GWAH! GWAH! GWAH!"Kelly was still inside of me, kissing my neck slowly and gyrating her. “Wow! Guess you two were very busy in there!” she said, laughing hard. She tugged at my shirt, examining it and the tell-tale wet splotches on it.“Is that... ?” She left the question hanging and Britney answered it.“Yes, Ma’am. It’s his cum. I hope that was alright,” she said.“Absolutely! Anytime! I trust he was a good boy?” she asked. She had trouble maintaining her compsure on “good boy.”“Yes, Ma’am, very obedient. I gather it was you that trained him so well?” Britney asked.“You betcha. It’s.
