The Dinner Party

She dipped her other finger in the truffle oil and wormed it between the cheeks of my ass, stabbing up to her knuckle. I let out a hiss of surprise, and realized she wasn't going to stop when I heard the front zipper on her skirt.

"The doorbell could ring any second!"

Her only response was the hot slap of her cock against my bare ass and her breath on my neck as she leaned over.

"If they show up I'll stop," she promised, nosing her thick tool into the cleft of my ass. She slid it up and down until the swollen knob of her prick bumped against my hole. Slowly but steadily she pushed forward. For a second or two I felt the pressure on my anus, and then my hole opened up as she slid smoothly inside.

I sucked in sharply, not from pain but from surprise at how effortlessly she entered me. It made me break out in goose bumps. We'd been doing this for years, since we'd met through a mutual friend when Aya was an undergrad, but no matter how many times we fucked it always made me shiver and shake. I let out a groan, and she kept pushing forward, feeding me three, then four, then five inches before pausing.

"You'll stop?"

"Yeah," she replied, though I wasn't sure she sounded sincere.

Dropping both hands down to my hips, she pulled me towards her as she pushed forward, burying the last three inches inside me, bottoming out, and I gave an involuntary grunt. I tried to breathe, but it was difficult; I was bent in half over the counter with my ass gaped open to the size of a golf ball around my girlfriend's rock hard dick.

"God, I needed that," she groaned as she withdrew, pulling back until only the fat knob of her dick remained inside me before shoving herself forward, her rod grazing my prostate as she bottomed out again. "All day, this is what I wanted."

My cock jerked and I could feel a small spasm of pre-cum force out the tip. She pulled back again and shoved forward again, knocking another grunt from my mouth and another spasm from my dick. Another withdrawal and thrust, and another low groan, over and over. I tried to keep quiet, but I couldn't. Every time her prick knocked against my prostate, the sounds just exploded from my throat. Again. Again.
