Practiced meaning what I do and where I go.I made sure I had my office ready for me to leave at the proper time. I was praying no one would stop me an... ask for my services as I almost ran from the office building.Getting into my car I headed home to change clothes, trying not to get a speeding ticket. Yes, I was anxious and my cock was staying at a heightened arousal. I knew my shorts would have a wet spot from all of the pre-cum that was flowing from me as I drove.At home I showered and. Don't stop. Yes! Yes! Right there! Ohhhhhhhh." She was pouring with sweat and was clawing at his back and screaming as they kept up the pounding rhythm of their insane fucking. She was getting close and he was trying hard to keep up with her, as she arched up and down faster and faster, pushing his cock in and out of her incredibly tight and taught pussy."I'm coming!" She wrapped her arms around him and held him tightly to her. He pounded into her as hard as he could. He could actually hear his. ..and it's my sister!" Still, she had made no move to escape our embrace, which got me to thinking... "Could...could I just feel your panties Peg?" I asked hopefully. "Just for a minute and then we'll stop. If we don't undress we won't risk getting in trouble, you know, if they come home." I knew Peggy well enough to know she would never say "OK! great! Go ahead and feel up my panties all you want!" So I took no answer as a "Yes" and led my pretty little red haired sister in law. He fucked her slowly the full 20 minute drive to the restaurant. Parking, she literally slid off his spurting cock getting out. They ate and having switched, Kirby fucked her the same way as they rode back home. The boys went into their shared unit as Pete and Helen went in the other. In 30 minutes, Pete opened the adjoining door thanking them for their sacrifice, then left. Kirby walked telling her that Ron said she was his for the night. She pulled him down kissing him. Kirby groped her.
