Been wanting to try this

I have to admit that the thought of rubbing my cock between this young coed's tits has crossed my mind more than a few times since I first saw her in those skimpy halter-tops she favored when the weather was still hot. Now that she has switched to sweaters and hoodies, it isn't all that much better, because I see still see the faint shape of her firm breasts pressing against the knit fabrics. When I get the chance to try out her tits, I'm hardly going to pass it up.

“No, stop!” Alison shudders when she feels my cock pressing against her pretty tits and her arms tug futilely against the bindings. “What are you doing?”

Instead of continuing the fake accent I remain silent, concentrating on groping Alison's pretty tits roughly as she lies tied down beneath me. I love the way her firm flesh bulges as my fingers dig into her and when I pinch her swollen teats and twist them between my fingers her head tilts back and she cries out in pain. “Not so rough, Master, I can't take this!” I twist the nipples even harder as I continue mauling her teenaged tits in silence. My victim however fills in the silence with a running dialog of her own.

“Oh God, he's groping me like I'm just a piece of meat to be used.” She gasps softly, shuddering when I let go of her and the blood flows back into the sensitive tissue. “He's making me realize I'm just a ****. A young, firm feminine body whose only purpose is to please men!” With a contented smile, I press her two mounds together creating a valley of soft flesh around my erection. Fran never let me fuck her tits like this, insisting that it was degrading, and I respected her enough that even on those special nights where she agreed to play 'slavegirl' I did not overstep her boundaries; with Alison though, I feel free to push the limits.

“Joe sure likes those titties of yours.” I chuckle as I start sliding my cock up and down between them. “He likes rubbing his dirty cock all over an Earth ****'s soft white flesh.”

“That's gross!” Alison moans softly but the way she licks her lips suggests that she likes being used this way. “Please, Master. I want to feel you inside me. I want you to make me cum with your big fat cock!” It is tempting to ram my cock into her once again, knowing that she is imagining that I am the second man to take her in front of her new mistress, but there was still more I could do with her in this position. I gather a mouthful of saliva before dribbling it down on the valley where her breasts sandwich my cock like a soft white hotdog roll holding my sausage.

“Der, now you good and wet fo' Big Joe!” I grumble coarsely in my lowest gravely range.

“You spit on me!” Alison seems genuinely surprised and not just acting, but when she feels my cock sliding back and forth in the newly lubricated tunnel, she arches her chest upwards pressing her breasts even harder against me. “You spit on me and now you're fucking my slick titties with your big, hard cock!” Something in her tone warns me that my lovely captive is getting too excited. I never seen a woman climax just by having her breasts stimulated, but I've heard it can happen and Alison is showing every sign that she is getting close.

“What?” Her gasp of frustration when I pull away is followed quickly by yet another halfhearted protest as I lower myself onto her face “Stop! What are you doing you disgusti-” the rest of what she was going to say is muffled by my scrotum pressing against her lips. By leaning forward, I can press my engorged dick up against her nose and I do that a couple times so she can smell the scent of an aroused man.

“Mistress Danielle says a nasty slut like you should learn to lick a man's balls!” I tell her and to my delight I feel her tongue tentatively start on the underside of my sac. I straddle her face in this position rubbing my junk in her face until I feel her start to lick me in earnest. My wholesome small-town tenant is apparently so far lost in this fantasy of hers that she is willing to do things that she would never even consider under normal circumstances. I even start shifting my body forwards and back so her tongue sometimes licks the base of my cock and at other times even laps at my anus. Whenever this happens, I quickly rock back so she doesn't realize I was intentionally making her lick me there. To Alison it is just another way she is being degraded in front of her hated rival, and I am content with that as well ... for now.

I switch back to fucking her tits, pushing nearly all of my weight against her mashed breasts. I got so excited by sitting on her face and making her lick me like that that I know I won't last long and fucking her firm young breasts is the ultimate reminder that I can do just about anything that I want with this submissive young woman as long as I take it nice and slow and make sure she learns to like her new role as much as I do.

My climax comes as a bit of a shock to me. I thought that I'd have more control over the stimulus of her soft breasts pillowing my cock; I really had expected to end up in her tight pussy again but instead I dump my load on her breasts as she gasps and wiggles under me. The sight of her on her back blindfolded and pulling frantically against her bindings makes the lines of semen dripping down her breasts even more erotic. As I kneel above her slender body pressed between my knees squeezing out the last little bit of spunk from my drained balls I wonder at how quickly I've fallen into my darkest fantasies.
