You get used.

"So," Kako says casually, "Do you like how my cum feels inside of you?" Your dick is currently trapped inside the muscular cockhole of your shemale girlfriend. "I think I want a lapdance from you now," she continues without waiting for your answer. She leads you to the couch. Your sac bounces off of your legs, hitting the backs of hers. "Quite horny, aren't we?" She stops and turns back to you. "You know, with all of this to grab, a girl could explode!" She literally jumps on you, wrapping her legs around your waist as she smushes your belly and works herself into your cleavage. You are surprised, and her heavy weight forces your back to a wall. She thrusts her cock at your crotch in lust. You can't resist her when she gets wild, so you let your hands grab her ass to support her. She is kissing your chest all over. You feel yourself ready to orgasm.

"Sorry, but I can't help myself..." Kako's orgasm explodes and pushes your own back down as once again she gives you a feeling of what it is like to be her. By the time she finishes, your sac rests on the floor; sticking out far enough that when Kako lets go of you, her ass is right on the top of it, and she sits down on you. "So, come on, you owe me a lap dance." She pulls you back to your bedroom, with the big mirror so you can watch.

She sits on the bed, and waits for you to begin. You start by shaking your sac for her. It ripples and you bounce it from leg to leg. You get up on the bed, and push her face into it. You wrap your hanging titties around her head. You work your nipples so a thin trail of your milk runs down her spine and into her crack. She shivers.

"You must like this," she says.
