I yawned. "Did mom dad see you come in here dressed like that?" She giggled, enjoying the naughtiness of the situation entirely too much. "They're...gone, I made sure to be up early enough so they wouldn't see my room empty." "You've put some thought into this, haven't you?" I asked. She struck a nervous, girlish pose and giggled. There was something very different about her since yesterday, like she was this wild sex kitten that I never knew about. Without missing a beat, she dropped her. Then I went to our screened-in room by the pool and flopped down in a chair.If the ice helped, I hate to think how I would have looked if I hadn't used it. After a sleepless night, I left early the next morning and drove to my sister's house in Sebastian. She was sitting in the kitchen, when I lightly knocked on her back door."It's good to see you're enjoying the holidays, Jim," she sarcastically offered as I sat in a chair across from her steaming coffee mug. "Was it a bus or a cement truck?. Running my fingers along the ropes and pulling at the knots, I began to figure out exactly how to untie them. Apparently I wasn't figuring it out fast enough."Please, Sir, just cut the ropes!" Daphne begged.I tapped her on top of the head and tsk'd her. "Quiet, you naughty slut, patience will triumph."The rope across her belly came off the easiest, and with her body free to move, she began grinding against the chair until I warned her with another tap on the head. The ropes holding her hands. I have to admit I hadn’t fucked such a big woman before. Having licked her a bit I pushed my cock in and began a usual fucking process. A bit later she stopped me saying:- That will do! I don’t want! That’s just a fucking! No arousal at all!I stopped feeling upset. She noticed that and said:- Hey, don’t be upset! I can suck it… - She lowered down and took my cock into her mouth.Although she was trying hard I couldn’t turn on any more…- Thanks, that’s Okay, - I stopped her.Then we parted and.
