She was shaking her hips as always, and I'm sure everyone knew she was a slut. Every now and then, Bill like to come up behind her and grope at her as.... He either sneaked his hand under, or lifted her skirt exposing her butt. He loved doing this in front of people. He would also grope at her tits, lifting them, pulling them apart, and sometimes exposing them. He loved showing her off, and letting her know she was his property. That day in particular, he kept doing all these things, but suddenly. "He glanced around and said, "I'm not worried about the cost. But where could we get in and get served?" We have to remember that not everyone has clothes to go to a fancy restaurant."Mike spoke up. "Let's go to McDonald's. Fast service and we can take over the place."Audrey and Terry both voiced their acceptance. We adults just shrugged and gave in. I suggested we get ready and wait for Marie and the other girls. Mike and Audrey headed up stairs. Tamara and I went to get rid of our bed. When it got down to where the only straps yet to be tightened were the ones around the neck, Kevin paused to unbuckle the strap for the hood and pull it up.“This straitjacket has a high collar, like a posture collar. I want to see your cock’s reaction when I tighten these last two straps.”When he tightened them, it started choking me a little. My cock immediately got fully erect and started leaking pre-cum. “I thought so. You’re turned on by breath control. When you wanted to have the hood on. “No im staying and there is nothing you can do to stop me” replied KatHe just looked at her then stormed off after Alice.“Who was that” “That was Alice’s boyfriend ………and my brother”Fuck this guy must really hate me now, oh well Kat's still here.After that we said nothing more, I led he back into my room and by the time we started kissing my cock was rock hard again. This time I ripped off my boxers as fast as I could I could not resist my desire any more. I took her by the waist and through.
