And I think I'd really like to well". This took me aback as my fuzzy mind strained to make sense of what I was just told."Would it be ok?" she asked w...ile holding my hands, "He doesn't mind if you come as well, just sex, you can watch", almost with a sense of pleading in her eyes. Again my mind scrambled for an answer and it felt like she really wanted to do this, and she did ask my permission so I felt in my mind that it was alright and replied "Ok, one night only, and I'll watch", which made. She’s being careful not to show it but I know how excited she is. She has probably figured out by now that Kyle is a virgin. I think the things we did yesterday turned her on a lot. I’m pretty sure she was even more excited by the fact that it was my first time.Now she’s going to introduce another boy to sex but I have some surprises in store for her. Today is going to be different.She hooked her thumbs under the waistband of her panties and began to slowly work them down over her hips. She. “Billy”, she said sternly, “watch Bobby and do what he does.” Stacy leaned forward quickly as if to slap me again and barked, “You’d better start stroking that little thing before I knock your damned head off!” I had jerked off before while looking at one of dad’s magazines, but I had never dreamed of admitting to it, much less committing the act in front of someone…especially a relative. With tears still rolling down my cheek, I took hold of my now erect, five-inch penis, and began shuffling. It penetrated a little. “Fuck, yeah,” he said. “More.”I pressed more and felt his muscle relax around my tongue. Not wanting to do something completely gross, I slipped my index finger inside. Dr. Cargill jumped at the intrusion, not because it was unwelcome, but because he wanted it. I worked my finger against his prostate and stroked his cock with my free hand. I felt pre-cum on my hand and used it as lube. He was getting close to cumming and I couldn’t help feeling proud of myself for that..
