But I went up shortly after them at 10.30 pm to find their bedroom completely quiet. I was disappointed. Then at about 12.30 am, I heard my Dad implor...ing me Mum to give him it. I heard her say that she was tired, but Dad kept on and on at her. He's very persistant. I guess it must have been about 2.00 o'clock before I finally heard my Mum start to moan as she finally gave in to him and he achieved penetration. I was really aroused and masturbating myself by the time I heard Mum and then Dad. She swallowed, and kept pumping his shaft and sucking any additional jizzm from his cock until he stopped thrusting his hips and settled back into his seat with a soft moan.She slipped his prick out of her mouth, still stroking it gently with her hand, smiled at Tyler and said, “How was that?”Tyler opened his eyes, released his hands from behind his head, massaged one of her swinging tits and said, “Fantastic, as always, Colleen. Great way to start a trip.”As Colleen shoved Tyler’s cock back. "I have nipple clips. Both the flat screw ones and the alligator clip ones. Here's some needles." They were long and extremely thin. They looked scary.What the hell do you use those for? he thought to himself."Oh! You can use this..." It was a large dildo with painful looking spikes. She pulled out a bottle of water-based lubricant and showed it to him. "It's not as good as silicone. You can use as little as you want to...you can make it hurt...I won't mind." She showed him a circular object.. Even though he was now completely comfortable with being in the nude in front of her, and his father, getting a boner in front of either of them was a different matter again.Tom was mulling over all these thoughts and the new impressions the day was presenting him with as he properly explored his surroundings. He found the stream that flanked the western boundary of the Success Nudist Resort and spent a few pleasant moments skipping stones across the tranquil surface of one of the stream’s.
