I then lifted my skirt around my waist and straddled his lap, rubbing my hot slickness against his hardened piece of black meat. I felt his cock was g...owing even thicker and then I impaled myself on this huge cockhead, gasping and shivering with pleasure.He looked into my eyes in the dim light and I began riding slowly, grinding my hips in small circles. His naughty hands found their way beneath my top, rolling and pinching my hardened nipples.I moved back and forth even faster, knowing I was. As with the belting, Gina did not have a specific number of strokes in mind but she continued to slash the cane down at full power, and Ryan was now reacting with yelps as he swung his buttocks, trying to diminish the sting. He clenched his cheeks in anticipation of each stroke, but he made no effort to get up and his penis throbbed in excitement.Gina was loving the patterns that she was creating with red lines on her son's buttocks and she was sweating both from her brow and her cunt as she. She was still twitching on the bed from that orgasm, when Steve2 said "Time to untie her" and Steve1 said "I was thinking the same". (I had been thinking of a re-tie so her ankles were tied to the same bed posts as her wrists but outvoted 2 to 1) She was untied and led over to a mat and told to kneel, she was then given each of our cocks in turn to suck and make and keep us hard, she did just that, sucking one and wanking the other two with each hand, We got her to do that for about 10 mins. I knew it had to be Kirsten that had fished out Frank’s boner and pushed it inside her as she got on his lap. He saw me looking back in the rearview mirror and grinned as he reached up inside Kirsten’s bikini top to play with her bare tit. Kirsten was obviously rocking on his dick slowly. By the time we were almost to my house she had one of his hands rubbing her clit, the other on her now exposed breast. Her skirt had ridden up all the way so everyone in the car could see everything they were.
