I had settled in and Bobby turned on the TV but it was hard to get that image out of mind of Bobby's sister just having bolted in here without any clo...hes on. But then there was Serena, sitting next to me on the couch, wearing a short little skirt, revealing long, dark, shapely legs. Plus she was bare-footed and I have a thing for cute, sexy feet.I thought I was coming over to watch some football with Bobby and the first thing that happens is that a fine black babe greets me with a warm smile,. He stopped moving and asked, “Right now?“If you want.”He suddenly moved, sitting up and looming over me he asked, “Really? Right now?”“You better get started before I change my mind again.” He flipped the sheet and blanket out of the way and said, “Look at that.” I looked to where he was pointing. There was a large wet spot on the sheet where he had shot his stuff. “I’m sorry…I should have gotten a towel or something.”I was slipping off my panties and I said, “Never mind. Get your tongue. And we both need to take a shower."We kissed, then I started to get out of bed."Hold on on a minute, Dear. I got you a present." She reached into her night table drawer and pulled out a wrapped box. It looked about the size of a Whitman's Sampler - those chocolates you get at the drug store for Valentine's Day.It was wrapped like a birthday present. I looked at the wrapping paper, trying to figure out what it was. There were symbols of different kinds. A six sided star, a top, a candle holder. Alzheimer grandmother. Hearing how much she enjoys this makes me happy. I keep finger fucking her, my arm is aching, in fact burning with pain because of the impossible angle and force it musters, but there is no way I am stopping. I keep kissing her, our tongues sharing all the wetness, and she is breathing into me. Her smell. Right into me. Into my lungs. I am drowning in her love. She can't stop making sounds, I can't stop moving my hand. Her eyes begin to lose focus. She throws her head.
