Seeing the glob of pre-cum emerge made my toes clench. The restriction of my boxers around my ankles only added to my pleasure. Working my shaft and n...pple at the same time for a few minutes was bliss. I kept looking as my foreskin kept enveloping my throbbing pink head, then peeling back like a flower going back into a bud. My balls contracted involuntary, cupping them I began to roll the egg sized spheres between my fingers. Kicking off my underwear I lifted my left leg and spread my ass. She giggles I say fine we are done here lets go .She pleads no no sorry for giggling.I say fine I will continue.2 I expect her to call me sir.3 She is to do exactly what I say without hesitation.4 She will wear a collar and leash while we play.5 She is to call Mike if she enjoys what we do and break things off with him6 she is to wear what I say if we go any further then this one play session.She says "everything sound good to her."I say Good now go downstairs and wait for me. I watch her. Except for the occasional nudity and the overboard kisses we shared, Mom, riya, and I where just another family.Each summer the three of us would spend mid-week evenings curled up together on the couch and watch movies. Mom, riya and I would pick one movie each, pop some popcorn and settle in. Riya sometimes fell asleep before the movie was over and I would carry her to bed. Sometimes, since it was her summer vacation, she would go out with her best friend priety and would not return in time to. Using KY Gel I lube it up and tease her hole with it. Gently pushing it deeper towards the girdle, the widest and toughest part to take. I eventually pop it past the sphincter with a small cry from Her. Only now has she realized something different is going on. “What is it?” she asks and I tell her. The girdle does stretch your arse, but I knew it was relaxed enough and her sphincter closed around.What I did not expect, is the flared end to go in too. The sphincter should have closed over that,.
