Your ass sticking up, ready for her...

She walks out of the bathroom with her lubed up dildo in hand, seeing your waiting ass she can't help but smack it with her free hand. The hard slap makes you jump and you whimper slightly in pain. She reaches down and begins to stroke your cock, shushing you as she gently strokes it up and down. Her other hand lines the dildo up with your ass and she presses its large rubber head to your little hole. Whimpering once more you begin to pant heavily, sensing your tension she releases your cock and uses that hand to spread your cheeks.

She slowly begins to insert her dildo into you, watching as your sphincter clamps down tight on its surface as it goes in bit by bit. You moan in pleasure and she giggles as she finishes pushing it in to you. "Do you like that baby?" she asks, your answer a simple and resounding "uh huh" and weak moan as she begins to pull it back out. The emptiness it leaves inside of you makes you push back towards her, trying desperately to get her to fill your ass with her cock again. She smiles as she begins to work it back inside of you, all the while as you push back steadily.

After a few minutes of warming you up, she begins to pump her dildo in and out of you a little faster, her lubed cock making a slurping noise as it penetrates your ass over and over. As you loosen up over time she starts to forcefully thrust it in and out of you, the pleasure making you find it impossible to resist reaching for your rock hard little dick. She sees your attempt and swats your hand away "Not this time baby, I want you to come with this cock in your ass and this cock alone..." She ceases thrusting her dildo into you, instead allowing you to rock yourself back and forth on it, fucking her dick in an attempt to get closer to orgasm. She laughs at the sight of your hard dick swaying back and forth as your eager asshole swallows her dildo over and over again. "Come on butt slut" she giggles at you "I wanna see you come like a girl"

You speed up, eager to please her and eager to cum as your face flushes with embarrassment at being called a girl. Each time you drive your little butt backwards takes you balls deep on her dildo. Your little cock pulses as you get closer and closer to coming with every push back. Eventually the time comes, and you draw your self forward until the head of her dick almost exits you. With one final, hard stroke back, you finally come, spraying your jizz all over the bed. Kay slowly removes her cock from your ass, motioning towards your mess. You don't hesitate as you bring your mouth to it and start to lick it up. She just smiles as she watches her new found obedient cock slut of a boyfriend.

After you're done cleaning your mess up, she tells you to go shower again. You do as you're told, wanting especially to get all of the lube off of you. You grab your clothes and head for the bathroom. Once in the shower you clean yourself off, half expecting Kay to jump you in there again, but she doesn't. You finish your shower and get out, grab your towel and dry yourself off. You look to where you placed your clothes but all you see is a pair of satin panties with a note on it...

Picking up the note, it simply says "Put these on baby, don't disappoint me...."
