All of a sudden It dawned on me what was happening. I remembered an erotic sex novel a friend of mine stoled from his older brother. In it everytime t...he guy saw a hot naked woman his cock got hard and for the first time in my life it was happening to me. It also talked about how he would shoot cum out of his cock and all I could think of was I didn\'t want that to happen in my pants.It was about then that I remebered the window in the back of our garage. I ran into the garage and locked the. . !!First things first, once Laura had released my wrists I scooted inside to undress and use the toilet, not sexy, but very important. Belly riders soon learn that a full bladder or bowel is not a good thing, causes all sorts of issues, so best remember. I also washed the ‘smudges’ Laura had applied as part of my slave look, towelled off just to start clean and dry, then slipped on a wrap to go outside, just in case.By the time I got outside, Deke had Spirit all ready to go, saddle and sling. This is really turning me on and although I can't see my friend well now I can feel his rock hard cock brushing against my ass and I know he is still turned on too. Bending over he licks my ass. Spreading my ass cheeks his tongue finds my asshole. I let out a shriek then a slow moan. I want to scream out yes yes so badly but I don't remembering his order to stay quiet I bite my lip and close my eyes enjoying my whole body tingling. I can't help moving my hips back to his tongue. He grabs my ass. Jill bucks with every lick and I swear they grow even more. Cupping my face Jill lifts my head from her breast and leans back on the couch before lifting and parting those long red legs, “You like?” She asks, her voice deep and husky with lust. I drop my gaze to the top of those stockings and there barely hidden behind the sheerest of satin thongs is her pussy, the sheer red gauze stretched tight over the fullest pussy lips I have ever seen, the cloth darkening as her juices flow. I look back.
