A New Obsession

My girlfriend Sonia had always been a little adventurous sexually, but she still caught me off guard when she started getting interested in anal sex. I’d tried it once with a previous girlfriend, but her asshole had been too tight and I’d never been able to get my cock all the way in. Since Sonia was a petite woman with an incredibly tight pussy, I figured she’d have the same problem, but she was determined to give it a try.

One night when she was riding my cock, straddling my hips with her short, slender legs, she paused bouncing up and down long enough to reach over and grab a small vibrator. As she resumed thrusting up and down on my throbbing cock, she reached behind herself and began to work the vibe into her asshole. I put my hands up on her small tits, covering them with my palms and working the nipples with my thumb to help her relax.

Sonia’s eyes were closed in concentration and she was breathing heavily, her chin-length hair falling forward over her face. Her normally creamy porcelain skin was flushed with the exertion. “Ooh, ooh,” she moaned slightly as she worked the vibrator into her tight asshole. I moved one of my hands down to her clit and rubbed it, thinking that if she came, her butt would open right up and take that tube right in.

I rubbed in circles, trying to hold back from coming, even though her tight, steamy pussy was sucking my cock inside her like a glove. Soon enough, Sonia moaned and pushed down as hard as she could on my cock, her hot cunt clutching around my shaft as she came. I kept up the pressure on her clit, and felt the vibrator sliding its way into her asshole through the thin membranes of her pussy.

“Yes! Yes!” Sonia groaned, and began stroking up and down on my dick again as she worked the vibe in and out of her asshole. Feeling the tip stroke along my shaft from inside her asshole turned me on so much I couldn’t hold back anymore, and I let loose with a hot spray of cum inside Sonia’s tight cunt.

Sonia kept practicing with the vibrator, and I helped her, because I was starting to get as interested in putting my dick where the sun didn’t shine as she was. One night, we were fucking from behind. I had one hand on her slender hips, helping her stroke back and forth on my dick as I worked the vibrator in and out of her tight asshole. Watching that brown pucker open and close to accept the vibe, stretching wider and wider, I couldn’t hold back anymore. I pulled it out and threw it on the bed, pressing my solid red dickhead against her anus instead. Sonia had been stretched out so well that with one thrust I was buried to the balls.

Both of us howled in pleasure as her tight ass accepted my swollen dick. Without any lube, I was able to slide back and forth in that hot passage. The friction on my prick was incredible, and I could feel my balls slapping against Sonia’s stiff clit, making her come hard with each stroke. Soon I felt the cum building inside my balls and I groaned that I was about to come.

“Do it,” Sonia said, groaning in ecstasy. “Shoot it in my ass.” I held onto her hips and thrust forward one more time, my dick throbbing as I sprayed her bowels with my thick spunk. I gave a few more strokes as my dick drained into her asshole, and then pulled out and collapsed beside her, holding her slender body in my arms and stroking her high cheekbones with my hands.

But here’s the thing - that successful ass-fuck did nothing to cure Sonia of her obsession. If anything, she wants it more now, more in her ass than in her pussy. And I am happy to oblige.
