She walked into the bedroom already naked from the waist down, bent over the edge of the bed, and spread her cheeks with both hands. "Fuck my ass tonight," she said, voice flat and direct. "No teasing. Just shove it in and pound it."
I didn't waste time with questions.

My cock was already hard from the sight of her puckered hole winking at me. I stepped up behind her, spit on my palm, and rubbed the head against her tight ring. She pushed back immediately. "Do it. Stretch me open."
I pressed forward. The head popped past her sphincter with a wet sound, and she grunted. "Yeah. Give me the whole thing." Inch by inch I sank into her ass, feeling the heat and the squeeze around my shaft. Her hole gripped me like a fist. When my balls finally rested against her, she let out a low moan. "Goddamn, that's deep."
I pulled back halfway and slammed in again. She rocked forward on the mattress but stayed spread wide. "Harder. Don't hold back." I grabbed her hips and started fucking her ass in steady, deep strokes. Each thrust made her cheeks ripple. The room filled with the sound of skin slapping and the wet squelch of her ass taking my cock.
She reached under herself and rubbed her clit in quick circles. "Tell me how it feels," she demanded.
"Tight as fuck," I said. "Your ass is milking my cock like it wants to keep it."
"Good. Keep going. Wreck it."
I picked up the pace, driving into her without mercy. Her moans turned into short, sharp cries every time I bottomed out. Sweat slicked her lower back. I watched my cock disappear between her cheeks over and over, the ring stretching around the girth. She was dripping onto the sheets from how turned on she was.
After a few minutes she pulled forward, letting my cock slide out with a soft pop. She flipped onto her back, pulled her knees to her chest, and held her legs open. "Put it back in. I want to watch."
I lined up again and pushed into her ass while she looked down between us. The sight of her hole swallowing me made her bite her lip. "Fuck yes. Fill my ass." I started thrusting again, this time watching her face. Her eyes stayed locked on the place where we connected. Every time I pulled out, her hole gaped a little before I shoved back in.
She reached down and fingered her pussy at the same time, two fingers sliding in easily. "I'm so fucking wet from getting my ass fucked," she said. "Don't stop until you cum in me."
I kept the rhythm brutal and even. Her ass clenched around me every few strokes, trying to hold me inside. The pressure built fast. I leaned over her, pinning her legs higher, and drove harder. The bed creaked under us. Her breathing turned ragged.
"Right there," she gasped. "Don't change anything. Just keep pounding my ass."
I felt my balls tighten. I buried myself to the hilt and stayed there, pulsing as I unloaded deep in her ass. She came at the same time, her fingers working her clit while her ass spasmed around my cock. We stayed locked together, breathing hard, until I finally pulled out. A thick trickle of cum leaked from her stretched hole.
She didn't move right away. She just lay there with her legs open, ass still twitching, a satisfied smile on her face. "That's how you do ass sex," she said. "Now give me a minute and we'll go again."
