I wasn't much of a cook, but I had fixed some spaghetti, warmed up some Italian bread, and opened a bottle of her favorite wine. I put a white tablecl...th on the kitchen table (we didn't have a dining room) and lit a candle in the middle."Robbie, I'm home," she called as she came into the apartment."In the kitchen Sis." My, my, what a treat this is," she said when she saw what I had done. The house did smell good.I smiled at her and said, "It's the least I can do. I guess I should fix dinner. I offered my services but she shot me down. No offense she said but after seeing those white pussy lips stretched tightly around shinny black cocks makes me horny for that same thing. I picked up my cell and as I started dialling I asked her again if she was sure. I said if he comes over there is no backing out, he will fuck you. She oozed confidence as she licked the rim of her beer, call that big black cock she said. I was doing it but I felt like I was actually watching a video. Sam answered. She screamed. She screamed in a combination of passion, pain andpleasure. "Yes! Give it to me!" she yelled."Oh, you fucking...hot slut," he panted. "I'm gonna fuck you...sohard...you won't...be able...to sit down!"He thrust roughly into her body, she panted and moaned loudly.He released her hair and reached under her and grabbed her arms out fromunder her causing her face to push roughly into the sheet. Bringing herarms back behind her, he pinned them as high as he could with one handwhile. I pulled it out a few times to calm my rising cum but then just put it right back in.I don't know how long we were going at it but Susan and Mark actually went to the bathroom for a few minutes and when they came out I was still fucking my grandmothers ass. Susan said something like wow he really loves your ass or something. I didn't pay attention just kept fucking that anal hole. Susan and Mark even started dressing and I was still fucking it. I swear it was like I had taken something to keep.
