I laugh and slap her slamming even harder, faster, and deeper into her, playing roughly with her tits, and pulling out a syringe, full of a extremely powerful aphrodisiac, and inject it into her thigh.
I cry out at the pain of the slap and at the force that he is using to slam into me. "Please" I whimper, still trying to wiggle out from under him. I feel a sharp pain in my thigh, and I look down and see a syringe. My eyes grow with my horror. "What was that?" I gasp. Before he answers though, I feel a large wave of pleasure wash over me and I moan loudly. "Oh, my..." my voice trails off as my body flames with want. I suddenly find myself pushing back to meet his thrusts, wanting more.
