I didn't really care, I just quickly retrieved my smallest strap-on, my 8 inch cherry popper, pulled it up my thighs and secured it around my waist be...fore thoroughly rubbing lube into the shaft as if it was real and I was jacking myself off. The whole time I was drooling over that cute little ass, even licking my lips when I finally got onto the bed and positioned myself in front of my prize.Spreading her ass cheeks with both hands I grinned widely, spat onto her lil butt hole, and then boldly.

There was no sign of her, so I made my way to the chilly bathroom to clean up. It was a dingy water-closet, really, with a black commode, a tiny, make-up stained sink, and a damp shower basin surrounded by a plastic curtain.
