"Yes, very lovely dear, but you're not holding yourself quite right, something to do with your hips, spread your legs dear."Kerri did as she was told ...nd moved her feet apart, placing both her hands on her thin waist. I got hard again just watching my sister's sexy features move around before me, the cleft of her bum catching a hold of the fabric of her panties."No, something's not quite right, I just can't put my finger on it though, take your panties off dear."I had yet to see a woman's. The thought that one of her neighbors or family would catch her sent chills up her spine. The cold bricks on her ass felt sensational. She would feel sensational. She wanted desperately to stay stuck in time. This was her universe and she could pee throughout time, reaching climax after climax. Her dreams would be dashed as the last dribbles of pee escaped her hole. She shook her lips dry.

He assured me that this was something that he'd always enjoyed. Many relationships had failed with him, but never because of something like this. I decided to go for it, and he set it up with her.

Inside was a black lace bra, thong with rhinestones up the back, garterbelt, silk stockings, and 7" patent. She grabbed my cock and led me to the bathroom. We took a quick shower together. "We have dinner plans tonight honey." She said."We do?" I asked.Her face frowned when I said this."You don't remember?" She said and I could see tears starting to well up in her emerald eyes."Of course I do Lizzie". I said as I dried myself with my towel and headed to the bedroom. She followed meI reached down into my pants pocket and pulled out a small jewelry box. I opened it and showed it to her. Inside there.
