Soon they were engaged in a hot sixty nine with Lisa's tongue swirling about the head of his hard cock and Dan sucking on her clit and fucking her wit... his tongue. A few more minutes of this and he was spurting all over her. Lisa tried to swallow as much as possible, but the constant twisting and movement as he made her come herself let a lot splash all over her face.Dan untied her and the couple headed for the shower. Lisa was surprised how easily she had fallen into the routine of showering. She looked at her friend and bit her bottom lip, she brushed her panties to the side to reveal her shaved pussy. her french manicured finger slide between her lips to spread the folds of her cunt for her friend (and horny brother) to admire. Her friend's hand slid from her breasts to in between her legs. her long finger tip round my sister's clit and scooped her wetness from her pussy entrance. she began to rub sissy's clit and my sister's hips began to move. she moaned and reached for her. “What was that?” I asked, leaning closer.“Nothing!”“Oh, I think it was something. Maybe if I tickle you, you will remember.” I threatened, moving closer.She scrambled to the other end of the couch, glaring at me.“I said, she wouldn’t do anything. She said she had to get permission.” Liesl spat, blushing but looking defiant.“Ah ... I see. Well, Linda, baby, my little fuck toy, you have blanket permission to sleep with Liesl, or just about any woman, really, as long as they are clean. No men. "*I drove around Tucson several times with my shorts and underwear around my thighs jacking off as I drove around. I kept kleenex on the seat to wipe the cum off of my belly, chest and sometimes my neck.*I had the upper bunk in our bedroom. The first time I jacked off there my semen hit the ceiling. From then on I used a sock.*I showed my neighbor Mark how to jack off. We wound up building a clubhouse in his back yard so we could practice our hobby. We would sometimes jack each other off.
