He didn’t wait but peeled off his jacket, vest, and shirt, kicked off hi shoes and pulled off his socks. The site of him, bare-chested, inky hair wi...dblown, was the most erotic thing she had ever seen. ‘Take off your clothes.’ His tone was almost a growl, and she found herself standing, repeating his action until she stood naked. His eyes raked her hungrily, deepening her arousal to a near breaking point. Silently Rafe crossed to the bed, lay in it against the pillows, and patted the empty. "On the other hand I better wait until you park. Carol just flashed her high beams at us. They probably know what we're up too."

But she had him, or rather his hard, throbbing cock in her hand, slowly squeezing it and bringing him along in what she called a "Marathon Masturbation."

I will obey whatever you say”. She put her feet down and asked me to pick. She knew I was going to spank her good and hard and seemed a little frightened that I might be too hard on her poor backside.I started to spank her flanks with heavy noisy slaps that caught Claudia and Tommy's attention making them get back to their own business with even more enthusiasm than before.It was with some relief that I retired to my own bedroom because it was starting to look like my slutty sister and her two teenaged cohorts were getting ready to make a night of it and fixing to.
