"God, you're such a slut."
Pushing at your forehead, Jessica forces you off of her cock, your drool glistening on the rounded head. Staring at it cross-eyed, you feel a slight pang of loss, missing the feel and taste of her cock filling your mouth, pressing down on your tongue. "Mmm... I think I'll keep you. You're a slut now, but don't worry, I don't pull out of sluts; I only pull out of loyal cockslaves."
As Jessica manhandles you around, you try to resist, quickly finding yourself bent over with her huge cock grinding against your behind, not quite sure how you got there so quickly, pants around your ankles, as you feel her hands firmly grasping your hips. Trying to pull forward, you're thwarted as she pulls back hard on your hips.
"Nuh, uh, uhh," Jessica taunts, squeezing at your hips, "this is for your own good. You're just a slut, you're worthless. Once you become my cockslave, you're going to have a purpose." Pulling back further, she thrusts forward, her spit slicked cock slipping easily into your tight ass.
Feeling Jessica grinding into you, you try to pull away again, struggling against the grip on your hips, only to moan as she thrusts again, pushing deeper. Then, something changes.
As Jessica's cock fills you, you realize something. You need this. You were meant for this. Fish swim, birds fly, and you use your ass to bring pleasure to a shemale cock. As Jessica begins to thrust steadily, working deeper into you, you relax, rocking back to meet the thrusts, movements becoming steadier, less panicked, as you instinctively relax into your role.
As Jessica feels you relax, her grip on your hips loosens, her fingers now massaging possessively at your sides and lower back, knowing that she no longer needed to hold you in place. Driven by base instinct, you were no more likely to try and pull away at this point, than you were to stop breathing, and she knew it. "Mmm. Told you you'd be my cockslave before I was ready to pull out. How does it feel, being able to fulfil your purpose in life?"
Moaning as Jessica begins to pick up speed, you clench down around her, feeling her grip your hips once again, holding you tightly as her cock throbbed, emptying her impressive load into your tight ass. For your part, you're only excited that you could be used to pleasure her.
"See?" she gloated, slowly pulling out, leaving you feeling empty and needy. "Not an aimless little slut any more, are you. You never realized how much you needed me until now."
