Fuck her asshole

I pull out of the still orgasmic Cynthia, turning her onto her side on the bed. I put my arms under the upper leg and raise it up, giving me easy access to her crotch. I then rub my still wet dick along her slit before moving to the side, pressing my slick dickhead against her anus. Cynthia lets out a low moan as I do, then a yelp as I push myself through the tight sphincter, her own wetness providing all the lubricant I'll need. I feel her anal muscle contract around my shaft as I push deeper into her ass, causing her to let out a squeal of mixed pain and pleasure.

"What are you-?" she begins to say but I cut her off.

"Shut up. I'm fucking your asshole, whore. Just the way you like it." Cynthia makes no move to protest and relaxes into the bed, letting me fuck her ass. I don't often fuck Cynthia's asshole but when I do she both loves and hates it and she can't help but orgasm from the stimulation.

I thrust into Cynthia at a leisurely pace, sliding in and out of her, my legs rubbing against her crotch, stimulating her clit while teasing her buttocks. I try to limit my own stimulation, while maximizing Cynthia's with my movements as I don't want to cum before I've reduced Cynthia to a lump of orgasmic pleasure, insensate and pure of though for anything but this moment.

Soon enough, Cynthia is moaning again, interspersed with the occasional yelp as I thrust too hard, her sphincter pulsing around my dick. If there is one thing I've learned about Cynthia and orgasms, it is that she is easily made cum drunk. Once she orgasms once, other orgasms can be made to follow with ease and she will give her consent to almost anything that might bring her further orgasms.

"Oh, god," Cynthia moans as she stretches her body, as if trying to get away from me and the pleasure building inside her. I chuckle and start to move faster, thrusting into her harder, pressing myself tighter against her, causing more stimulation on her clitoris. With a low moaning gasp that sounds something like "Yeeeeaaasssh," Cynthia cums again. She spasms twice, her body curling into a fetal position as far as she can before stretching again, and then she relaxes, breathing heavily as I continue to thrust inside her unresisting body.

After a few moments, Cynthia begins to recover. She still lies motionless on the bed, letting me do the work of thrusting in her but clearly still conscious and alert, despite being cum drunk silly, as evidenced by her orgasmic giggles. If I want to fuck her into orgasmic unconsciousness, I'll need to up my game a bit.
