Two raised rests for someone to kneel upon and then a bench for the torso. Wooden made, it was covered in thick padded black leather. Attached to the ...ests were two black leather straps, one for the ankles and the other for just below the knee. On two uprights were two similar straps for the thighs. In the bench for the torso were larger straps for the waist and upper chest. On the sides of the bench were sets of straps designed to fasten wrist and arms. Julie said nothing as she took it all. And then it was time to change into the sweats and get ready for bed. I was embarassed, because living all together in Section 20 had removed any vestige of modesty. I tried not to stare at the brief flashes of pale skin or dark pubes or puckered nipples, then realized they were flashing me on purpose, and grinning at my increasingly red face. I glared at them as I tried to quash my grin. Suddenly I realized that I was the only one who hadn't changed into my night clothes yet. I blushed so red. It felt really odd in her ass while dad was driving in and out of her, like a hand was inside her gripping my cock. I kept it up for a while, but then I had to stop. "Mum, dad, wait. This is harder than I thought." Dad stopped and mum looked over her shoulder at me inquiringly."Look mum, it'd be better for me if dad stayed still and I drive into you from on top." OK dear, we'll try that," she said. "We'll get it right with practice."Dad held her tight and kept his cock buried deep in her pussy. Arianna rose from the dripping wetness of my shaft and shuddered above me, her cum dripping over my hard shaft even as Brandy sucked me into her mouth, humping my face to maintain the peak she had found. I lowered my head and with rough aroused voice said, “You two need to switch off,” and gasped at the flood that still seeped from my little girl’s pussy. It wasn’t like I would mind cumming in the blond beauty, but Brandy deserved the first load if it was possible. She rose from me as if her.
