I realized my elderly mother-in-law was a big anal sex freak. Our first sex was apparently just a foreplay to more passionate games. I decided to do t...he utmost to make her feel sheer bliss.My tongue moved between her buttocks and concentrated the entire caress on her hole. She was moaning and swaying her pelvis. Her hands were fondling her boobs or spreading the buttocks wider impaling the ass on my tongue. We spent some time fondling that way. My partner had obviously come several times, I was. Her hand that wasn't manipulating her nipple reached for his head. He ran it through his hair forced it back down to lick and suck her clit. He took the hint and continued his assault on her. Kari's hips gyrated to meet him and they found their rhythm quickly. He pulled his fingers out, and his tongue was next to slip in. She had never felt anything like this and the gyrating turned into wild bucking. Like her mother earlier, she was now the bitch in heat, needing to cum, needing her brother to. He told Amy they were going to be out tonight so she could do whatever, even call a guy over.Amy thought about it and decided to do just that. She was hoping she would get fucked so hard and good that she would stop thinking about brian.Rock and Brian left. They were on their way to a house part being held by one of Rock's fraternity brothers. When they pulled up it wasn't just a house, it was a fucking mansion. It had tons of rooms and a nice big pool. They had got there a little early to help. About that time this cute girl, just like Connie had described herself came running over and they started laughing. I said, “Now I’ve been tricked and you’re a little shit!” She said this is my brother Dan. We all laughed, Dan and I shook hands then he left. She snuggled up to me. She had on a black way low cut sweater with lots of cleavage, a white pleated short skirt, with hot legs and a beautiful face. We talked a minute and then she said, “I’m not through with you yet, bad boy. Let’s go.
