She bent over the edge of the bed, ass up, and told me to eat it. No teasing, no warm-up. Just "Lick my asshole, now." I dropped to my knees behind her, spread her cheeks with both hands, and stared at the tight pink ring winking at me. It looked clean, smooth, and ready. I dragged my tongue flat across it in one long, slow stroke from the bottom of her pussy up to the small of her back. She groaned and pushed back.

I went straight to work. My tongue circled her asshole, pressing firm circles around the rim, then flicked right over the center. She tasted like soap and skin and a faint hint of her own musk. I spit on it, watched the saliva run down her crack, then dove back in, shoving my tongue as far inside as it would go. Her asshole clenched around the tip, hot and tight. I fucked her with it, pushing in and out, making wet, sloppy noises that filled the room.
"Fuck yes, deeper," she said, voice low and rough. She reached back and pulled her cheeks wider for me. I buried my face between them, nose pressed against her tailbone, tongue working nonstop. I licked her asshole like I was starving, alternating between broad laps and pointed jabs that opened her up a little more each time. Her pussy was dripping down her thighs; I could smell how turned on she was. I slid two fingers into her cunt without warning and finger-fucked her while my tongue stayed busy on her ass.
She started rocking back, riding my face. "Tongue fuck that hole," she ordered. I stiffened my tongue and drove it in as far as it could reach, then wiggled it inside her. Her asshole pulsed around it. I pulled out, spat again, and went back to long, filthy licks from her clit all the way up over her asshole and back down. She was soaked. I sucked on her pussy lips for a second, then returned to her ass, sucking the rim gently before spearing it again.
I kept at it for a long time, switching between fast, sloppy rimming and slow, deliberate strokes that made her moan louder. Every few minutes I'd add more spit, letting it run down so my chin got wet. My jaw ached but I didn't stop. She reached down and rubbed her clit while I ate her ass. "Don't you fucking stop," she growled. I answered by shoving my tongue deeper and curling it, trying to fuck her open.
When she came, her asshole squeezed rhythmically around my tongue and her thighs shook. I kept licking through it, softer now, just gentle laps while she rode it out. She collapsed forward on the bed, breathing hard, but I wasn't done. I pulled her cheeks apart again and went back in, slower this time, tracing every fold of her stretched rim with the tip of my tongue. She whimpered and pushed back for more.
I stood up, wiped my mouth on the back of my hand, and lined my cock up with her pussy. She was so wet I slid in easy. While I fucked her, I kept one thumb pressed against her asshole, rubbing in small circles. She came again on my cock, ass clenching under my thumb. I pulled out, dropped back to my knees, and licked her asshole one more time, tasting her pussy juices mixed with the spit I'd left there earlier.
She flipped over onto her back, spread her legs wide, and pulled her knees to her chest. "Again," she said. I crawled between her thighs and went to work on her exposed asshole from this new angle, licking and sucking while she watched me. Her eyes stayed locked on mine the whole time. I made it loud and messy on purpose, letting her hear every wet sound. She came a third time just from my tongue on her ass, legs shaking, fingers tangled in my hair, holding me right there until she was done.
Afterward she pulled me up and kissed me deep, tasting herself on my tongue without hesitation. Then she pushed me onto my back and returned the favor, but that's another story.
