A beaded toy

She lifts from the box a thin beaded thread, a sort of string, and beats me gently on my nipples with it. Then, she lays me on my back, caresses my penis, and slowly, surreptitiously feeds the thread of beads into my ass. It's a strange sensation, not totally unpleasant though, slippery and sensuous. She pulls the beads out slowly, then re-inserts them casually. I regret to say I feel my prick thickening, swelling with feeling.

Then, without warning, she abruptly impales herself on my stiffened cock, I feel her ravening pussy lips grab and grasp me with abandon, until she exhausts herself with a sigh of relief.
