"Mine, too, babe. We took a strap-on each in the ass, but not a hard cock. I propose that we each sit on Franco's dick and ride it for a while. Pussy ...this time. Think how great it will be to have him fuck us that way, Minnie!" Gloria exclaimed with undeniable anticipation."Of course. Or maybe I can eat you out while he rams me from behind. Then we can switch places and he can take you while you eat me out. But your idea is good, too. Maybe we can do both. The nannites do wonders, after all,". "Not yet, James......come here" she ordered and undid the harness holding the strap on.I stood up, my cock semi hard and still oozing cum.Lori told me to lay back and now she mounted me in a 69.I dove into her wet pussy, licking and sucking her clit while she sucked on my half hard cock."Now Eric, shove that big prick inside me" Lori ordered.I watched from underneath as Eric came up behind Lori and slid his cock between her pussy lips inches from my face.My cock grew hard again in Lori's mouth. " Louder" Please make me cum. Please. I'll do anything."Mark is staring at his sister in what I can only describe as total amazement. "Say it louder, Barb." I want Mark to fuck me!" I look at Mark. He has the biggest shit eating grin any human has ever had. "Yell it out. Loud enough for him to hear you downstairs." Please, Dave. I'll do anything." We are waiting."She laughs. Then she says louder than I was expecting, "I want Mark to fuck me!" As a reward I finally and mercifully bring. I pulled my own clothes back on and checked the hallway to see if the coast was clear. I snuck back down to the family room and was sitting there by myself watching a movie on the TV when her dad came in from the garage. He was very nice to me and asked how long I'd been there. I told him the truth about how long I'd been in the house, but said I'd been watching a movie the whole time because I didn't know where he or Carolyn were. He answered he'd been trying to find a manual for the lawn.
