She kept bobbing and bouncing her fat black ass on my dick. I could feel her pussy getting wetter and wetter, and her pussy muscles squeezing tighter....And I could hear the wet "squish" of her pussy every time her ass bounced on my lap. I was enjoying it. A lot."So you are eighteen, huh?" I asked."Yeah, I'm eighteen!" she said, bouncing her ass harder on me. "I'm eight-fuckin'-teen!!"Then her cell phone buzzed. She stopped quick and picked up her phone to look at it, and right away went into. Feeling in a particularly horny mood, she thought she would borrow some of her mother's sex toys, pull out some of those fuck books she kept hidden under her mattress and diddle her pussy till she was satisfied.She bounded to her room. When she flung open the door to her room, she got the surprise of her life.Andy was on the bed, naked, a hard-on as huge as a baseball bat dancing in front of his crotch. He was half on his side, propping his head up with his hand."Hi, Tess!After Tess recovered. .." She rubbed my arm. Sex was an option -- but not one I wanted to pursue. Nana seemed to know that. "You need to relax. No one in the family is here to bite you." I already have your teeth marks!" I replied, grinning."Yes, well, I've gotten my fill of your blood, for now," she teased. "A bath, perhaps? Some nice, warm water?"I remembered a recent evening. "AI, is there a whirlpool or a sauna available locally?" At the end of the corridor. Approximately forty-five meters," the voice in the air. Please, haven't you had enough?" Aaaaw," mocks another man, "the poor little bitch is sore. Maybe we oughtta help her up." He grabs my hair and yanked until I was on my feet. Another man pulls my arms up and back until I can feel the corner of the stall pressing against my spine. My arms being pulled up, I have no choice but to stand on my tip-toes as someone passes a dirty handkerchief over my head and it is used to tie my hands around the support for the stall.The men stand back to admire.
