"We can't do it here," the girl gasped when their mouths parted, his huge, wet cockhead in the palm of her hand. "Let's go downstream a ways." She was...already warm and ready.Hand in hand they trotted to a grassy place on the river bank, well concealed except from the water. Billy stripped off his clothes and tossed them to the ground, his eager prick jumping up and quivering, oozing gobs of pre-cum. He pulled off the girl's shirt and bent to suck and kiss her nipples before laying her down on. Once youhave situated your gonads and penis up and away, there will be notelltale bulge." I know how, Momma!" I cried. 'Bet she and Daddy NEVER thought about metaking care of things.'"WHAT?"I held up a skin tone panty with a realistic vagina in front, "I'vealways worn a panty brief that took care of things for me." You have more than one?' she asked with Spockian eyebrow as sheinspected it."Yes. I have another so that I can have a fresh one, every day." How do you clean them?" A good soaking in. She was leaning forward and with each thrust I could see her heavy breasts swinging back and forth. From the fucking sounds I imagined my dad’s hands on her ass, and how he was pounding her from below. All of a sudden I had this vivid image of me climbing out of bed, moving over to their bed side, leaning in and starting to suckle one of her nipples as dad kept fucking her.I almost had to pinch myself to make sure it wasn’t happening. My hand started stroking faster and faster trying to keep. She was gradually turning the power up on the shock collar until it felt like my balls were going to explode so I stopped asking questions.In a weird so of way it still felt like a vacation to me other than the fact that after a few days I was horny as hell but since I was continuously wearing her other device, there was nothing I could do. She didn’t even tie me up when she needed to take it off for measurements. I had no clothes and my car was locked up somewhere off her property. She simply.
