Accidentally fucked my girlfriend in the ass during sex

Freshman dorms usually had a bad smell, but with my girlfriend, Emily, in my bed, naked and tangled in the sheets, all I could smell was her fruity perfume and feminine scent. Friday night, nothing to do but each other.

She lay on her stomach, propped up on her elbows with her long blonde hair fanned over my pillow, scrolling aimlessly through TikTok and humming softly. Her ass caught every glint of the ceiling light, glowing smooth and pale, the curve of it almost cartoonish in its perfection. She was smaller than me, only about 5’4” compared to my six feet, but her body had this tightness I was completely obsessed with. C-cup tits, perky even when she was slouching, and a slim waist that fit perfectly under my palm. Her ass, though, that’s what kept me up at night. Round and soft, with a tiny dimple above the crack and a little mole on her right cheek. I’d never seen anything hotter in my entire life.

I watched her for a minute, letting my eyes wander down the line of her spine to where her hips flared out, drinking in the sight. Even if I was also naked, she hadn’t noticed my hard-on yet, or maybe she was pretending not to, but I didn’t care. I reached out, cupped one cheek, and gently squeezed it. The flesh gave under my palm like memory foam, springing back when I let go.

She glanced over her shoulder, big blue eyes lighting up with that mix of shyness and mischief she’d perfected since the night we met. “Hey, hands to yourself, perv,” she said, but didn’t move away.

I smirked and rolled over her, pinning her wrists above her head with one hand, my cock pressing hard against the back of her thigh. She giggled, squirming as I peppered her neck and shoulder with kisses, then nipped lightly at her ear.

She wriggled, laughing and trying to pull her arms free. “Ryan, you’re such a dork,” she said. I ground my hips against her ass. She could feel me, thick and eager, and I knew she liked it when I was aggressive like this, even if she’d never admit it.

I trailed my hand down her spine then down to the base where it met the soft swell of her cheeks. She had a faint tan line from her high school cheer uniform, the faintest blush at the top of her ass. I traced the line with my thumb, smiling when she shivered.

“Can’t help myself,” I said. “You’re literally the hottest girl I’ve ever seen.”

She rolled her eyes, but her face flushed pink, and she bit her lower lip. “You’re so cheesy,” she whispered. “It’s not even funny.”

I kissed the spot right between her shoulder blades, tasting her skin. “I’m dead serious. And you love it.”

She groaned, but didn’t argue, arching her back slightly so her ass pushed up against me. The move was subtle, but I caught it.

We’d been seeing each other for two months, but it felt longer. I’d had girlfriends before, but none like Emily. She was shy in public, barely made eye contact with waiters or strangers, but in my bed, she’d loosen up, giggle at my dumb jokes, and sometimes even beg for it if she was tipsy enough. The only thing we didn’t do was anal.

I’d hinted at it, joked about it, even tried to convince her after she’d given me head and swallowed every drop, but she’d always squirmed and said no, not yet. Sometimes she’d blush and say, “You’re too big,” which only made me hornier, but I never pushed her. I knew it was a trust thing. Still, the idea of finally being inside her ass drove me insane.

Tonight, she was extra cuddly. I could tell she wanted me to take the lead, so I slid my hand between her thighs, fingers brushing her pussy. She was already wet. She moaned quietly, burying her face in the pillow, her hips tilting up for me.

I ran the head of my cock up and down her slit, just teasing the opening, then slid inside with one slow thrust. She gasped, then exhaled with a little whimper that got me right in the chest. She always felt so tight the first time I pushed in, like her body was still learning how to take me.

I started slowly, holding myself up on one elbow so I could kiss her neck while I rocked in and out. She squeezed my forearm, nails digging into my skin, moaning every time I bottomed out. Her pussy made these soft, squishy sounds, the kind that would have embarrassed her if she were sober, but right now she was too lost in it to care.

“God, you’re so wet,” I said. “You feel amazing.”

She giggled, face still buried. “You’re just saying that.”

“No, I mean it,” I said, picking up the pace. “You’re perfect.”

I shifted up, kneeling behind her, and grabbed her hips with both hands. The angle changed and I could see everything: her pale back, the bounce of her tits as she pushed up on her hands, the way my cock slid in and out, glistening with her arousal. My favorite view in the world.

I bent over and pressed my lips to the top of her ass, then gave her a gentle slap. She squeaked in surprise.

“Ryan!” she said, turning her head to glare at me, but there was a smile in her voice.

“Couldn’t resist,” I said, squeezing both cheeks in my hands.

She shook her head and pushed her hips back, grinding against me. “Just fuck me already,” she whispered, and I didn’t need to be told twice.

I started pounding harder, the slap of skin on skin echoing off the walls. She moaned louder, the sound raw and needy, and her hands clawed at the sheets. I watched the way her ass rippled every time I bottomed out, the way her pussy hugged my cock, so tight I could barely pull out.

I felt myself getting close, the pleasure building with every thrust. And it just made me fuck her harder, our flesh slapping. As I started fucking her harder, I accidentally slipped out of her pink pussy, which gaped open for a second before closing. Then the head of my cock slid up too high, glided through her slick slit, and bumped right up against the tight pink ring of her asshole. Then I pushed forward, just a little. My cock was so wet from her juices that the tip popped past the ring, and suddenly I was inside her ass.

Emily’s whole body snapped upright, her back arching like a bow. She gasped so loud it echoed down the hall.

“Ryan! That’s my ass!” she squeaked, voice wild with panic and confusion.

I was so shocked I didn’t move. The feeling was unreal, so much tighter than her pussy, like I was being strangled by a warm fist. I knew I should pull out, but it felt so damn good. All the blood had left my head.

“Oh fuck, sorry, Em, I didn’t mean to,” I stammered, hands going slack on her hips. But I was still inside her, maybe two inches deep, and I could barely breathe.

She stayed perfectly still, panting hard. Her ass clenched down on me, making it even tighter. “Oh my god,” she whimpered, voice shaking. “It feels so weird…”

I started to pull out, but she reached back and grabbed my wrist, stopping me.

“Wait,” she said, eyes squeezed shut. “Just wait. Don’t move.”

I froze, afraid to make it worse. I could feel her heartbeat, every pulse squeezing my shaft.

“I’m so sorry,” I said again. “Do you want me to pull out?”

She paused, then she nodded. “Just go really slow. I’m scared it’ll hurt if you do it fast.”

“Okay,” I said. I eased back, millimeter by millimeter, until just the head was inside her. She let out a little sigh, then bit the pillow.

“Is it okay?” I asked, barely moving.

She nodded, hair sticking to her sweaty cheek. “It’s… intense. Really full. But not as bad as I thought.”

I stayed like that, just letting her adjust. My cock throbbed, the ring of her ass gripping it so tight I thought I’d explode.

“You’re doing so good, Em,” I said softly. “You’re amazing.”

She opened her eyes, shy and uncertain. “You can go a little deeper,” she whispered. “Just… be gentle, please.”

I pressed forward, slowly. The pressure built, then eased as her body gave way. I was halfway in, and she whimpered, but didn’t tell me to stop. “That’s it,” I said, rubbing her back. “You’re taking it like a champ.”

She let out a shaky laugh. “You’re such a dork.”

I held her hips and started moving, shallow at first, just enough to let her get used to it. She gripped the sheets, body shuddering as I slid in and out of her ass. The sensation was mind-blowing. Her asshole was scorching hot and really tight, clenching around me with every shallow thrust. Every ridge and muscle inside her gripped my cock, squeezing and fluttering as she adjusted to the intrusion.

I kept the pace slow and gentle. The initial tightness slowly gave way as her body relaxed, allowing me to sink a little deeper with each careful anal stroke.

“You’re doing so good, baby,” I murmured, rubbing her lower back soothingly as I stretched her ass. “You’re so fucking tight. It feels incredible.”

She let out a broken moan, pushing back against me just a little so her cheeks were pressed against my groin. “It’s starting to feel… good. Don’t stop.”

Encouraged, I fucked her a bit harder, still keeping my thrusts controlled. I could see her tiny pink rosebud stretching around my thickness, the sight alone pushing me closer to the edge.

Emily’s moans grew louder and needier. She started rocking back to meet me, her shyness melting away as pleasure took over.

“Ryan… oh fuck, it’s actually feeling really good,” she moaned, her voice cracking. “Deeper… just a little.”

I gave her what she asked for, thrusting deeper, my hips slapping against her soft ass cheeks. Emily’s whole body trembled, her legs shaking as she pushed back harder. Then I buried myself as deep as I could go, my cock throbbing violently inside her tightest hole. With a deep, guttural groan, I came hard: thick, powerful ropes of cum erupting deep into her virgin ass. Pulse after pulse flooded her, filling her completely.

I stayed buried inside her as we both came down, breathing hard. When I finally pulled out slowly, a thick stream of my cum immediately trickled from her slightly gaping asshole, running down over her swollen pussy lips and dripping onto the sheets.

Emily collapsed onto her stomach, panting, then turned her head to look at me with wide, dazed eyes and a shy, surprised smile.

“I can’t believe we just did that,” she whispered. “And… I actually liked it.”

I leaned down and kissed her shoulder. “You were perfect, Em.”

She buried her face in the pillow, giggling softly. “We are so doing that again.”

I grinned, kissing the top of her head. “Anytime you want, baby.”

We lay there, tangled up in each other, and I knew I’d remember this night forever.
