An Easy Mistake To Make

After I got back from an early dinner, I stepped into the room and did a double-take. Her shaggy black hair was chin-length, but with her pixie face, her gorgeous ass in tight jeans, her massive boobs almost bursting out of her pink tank top, and her trim waist, it was clearly a girl who was setting up a monitor on the other desk.

I stepped back outside and checked the door. Still 396.

I stepped back inside and looked again. Yeah, that was still my comforter on the bed, still my computer set up on the other desk, and still my backpack in the corner.

"Um—I'm Mike," I said nervously. "Is this some kind of mix-up? I thought my room was 396."

She stood up, brushed her bangs out of her eyes, and gave a sweaty grin. God, she was gorgeous.

"I'm Alex," she said, proffering a hand. I shook it. Her hand was soft and warm, and I felt a chub forming in my jeans.

"Is that short for—?" I started.

She shook her head. "No, it's not short for anything. My parents wanted to give me a unisex name, and they know that it can be short for Alexan

dra

or Alexan

der

, but they wanted to keep it simple."

"So is that why—"

"Yeah, it's probably a mistake. My room card definitely says 396, too. Lots of people think I'm a guy when they see my name; it's an easy mistake to make."

"Do you think we should get it fixed?"

She shrugged. "I'm cool with it if you are."

I hesitated. It was probably against some sort of regulation or something to have a dude like me rooming with a girl, and this would probably make lots of stuff awkward. But on the other hand, she'd probably be better at giving me girl advice than my clueless stoner roommate had been last year, and besides—a hot chick like Alex? As my roommate? I imagined seeing her coming from a shower, wrapped in just a towel. Seeing her sleeping. Fucking her doggy-style.

Down, boy

. I'd be an idiot to give up a chance like this, no matter how unlikely that last scenario was, and no matter how awkward this might be.

I swallowed hard. "Yeah, I'm cool with it. Nice to meet you."

I started to suspect that I might not be the only one benefiting from this arrangement later that day when I was ready to take a shower. "I'm—I'm gonna go shower now," I announced awkwardly. I generally like to let my roommates know where I'm going just in case they need to know.

"Fine by me," she said from her bed. She was sprawled on her bed scrolling through her phone, and I was grateful that I only had a chub. I couldn't help but glance over to her bed as I stripped; her body looked so soft and pliable the way she was flopped over. And was she looking at me? It's not like I have a great body—I go to the gym a little, not a lot, and I don't shave my chest or anything—but when I stole another peek, I could tell that she was staring at my abs. Hungrily.

I could get used to a girl looking at me like this—and it's a good thing that I'm showering now before my little boy turns into a big boy!

*

Of course, soon it was her turn to take a shower, and I regretted that I was on my laptop as she stripped right behind me. I knew it would be pervy if I turned around in my chair and stared at her body, but I could almost feel her body heat as she took off her clothes. I caught a glimpse of her slim, curvy body just in a towel right before she left.

And when she was back, I was sitting in bed with one of my textbooks. It's the way I normally read textbooks—and I got a great view of the half of the room with the closets and desks. Plus, this way the textbook might hide any erection I might get.

She strolled in, her slim, pale body wrapped in a towel, as she hunted for clothes.

Damn.

"You really don't mind?" I said.

She shrugged again. "I don't really care. We're roommates, right?"

*

Later that night, I was trying to sleep, and trying not to stare at her sleeping body. Even through her thick pink blanket, her body somehow looked soft, squeezable, and sexy. Thank God my black blanket was thick, since otherwise my erection would have been visible. I wasn't quite sure how to bring up the subject of masturbation, and I knew I'd have to relieve myself soon. My stoner roommate from last year had just done it at night and pretended I couldn't hear, and he didn't care if I did or not; my geeky roommate from the year before had insisted on trading class schedules with me and worked out a code system: "You got time" means "I'm going out for at least an hour." I was definitely going to need to work out some system with Alex, and soon, since it had been ages since I'd been this horny. And was that motion under the covers? It almost looked like her arm was going up and down at her crotch—was she masturbating?

Well, I didn't mind at all seeing her masturbating, but it's a little weird seeing a sexy girl do it. I definitely wanted to join in—but wouldn't she mind? It was cool with my stoner roommate since we were both straight, but it's totally different if my roommate is a girl.

She moaned lightly as her hand sped up. Yeah, she was definitely masturbating, and my dick was now rock-hard and straining in my boxers, begging to be touched. I groaned and rolled over, so at least I wouldn't see her.

Soon it was absolutely obvious what she was doing: she was panting firmly, rhythmically, strongly.

Fuck

. I was definitely going to imagine this the next time I jerked off—but that didn't help me now. You don't just masturbate when your roommate thinks you're sleeping. So I alternated insisting to my overeager dick

No, not right now, down, boy, your time will come

and straining my ears to listen to every one of her delicious pants.

Soon her breathing got even heavier, thicker. It was a supreme act of willpower to keep my hands firmly clutching my blankets and well away from my boxers. I could imagine her making the same rough pants if I were fucking her in missionary, her smooth legs spread, my dick plunging deep into her—

She moaned again. "Mike," she whispered in a sleepy voice. Then she moaned again, harder, like she was cumming. I thrilled at the sound as I struggled again to control my breathing and struggled to keep my hands away from my aching dick.

*

As sexy as she was, I was incredibly grateful the next morning when she woke up before me. I woke up in time to see her sling her backpack over her shoulders and step out the door.

Thank God

. I waited five minutes, since all of my roommates sometimes came back for something they'd forgotten. Exactly five minutes.

Then I lowered my blankets, lowered my boxers, and went to work. My dick felt so thick in my hand, and so hungry. It had been less than two full days since I'd last masturbated, but it could have been a hundred years, I was so desperate to finally have my hand going up and down my dick. I stroked up and down like a starving man who is so hungry he can barely taste his food. It was only a few minutes before an orgasm knocked my breath out and wracked my body as semen spurted and splattered across my chest.

Morning session notwithstanding, it was difficult to concentrate on my classes. My mind kept drifting to what I'd seen and heard last night: Alex's cute butt, her perky boobs, her slim body in just a towel, and most of all, her panting the last night. It was definitely a mixed blessing rooming with a hot girl! So obviously I needed to work out some sort of a system.

That night, after both of us were in the room for the night, and I'd already showered, I said, "Hey, Alex, do you have a minute?"

"Sure, what's up?"

"Well, we already traded phone numbers, but do you think we could trade schedules too?"

"Of course. Do you want to copy my printout? Or should I email it to you?"

"I'll just copy your printout. Here's mine," I said, pulling the printout of my schedule out. It was only a moment before she had hers as well, and I made a note of each of her classes. Most of them were at the same times as mine, but she did have some long Tuesday and Thursday morning classes that I could make use of.

"Thanks," I said, handing her back her schedule. "And another thing—could you let me know when you're going to be out for a while? Like, with my first roommate, if he was going to be out for more than an hour, he'd say 'You got time'."

"Sure. Actually, normally with my roommates, I tell them when they should expect me back. I'll text them before I stay overnight somewhere. That way they'll know if they should call the police or if I'm just getting laid."

"Does that happen a lot?" I said. I didn't know what to think about Alex getting laid. It was hot thinking about her fucking, but I didn't want to think about her fucking other guys.

"What, getting laid, or calling the police?"

"Both," I said, blushing.

"Calling the police—happens," she said. "None of my roommates called the police on me, but I've called the police on my roommates before. You do what you have to do." She gave a small shrug and a wry smile. "And getting laid—well, I fuck when I want." She gave an impish grin.

I felt turmoil again. Thinking about Alex getting laid was hot, but frustrating.

"And what if you wanted to get laid here?" I said. "I could go to the library if you text me in advance," I offered.

"Really? OK, I'll give you as much notice as I can if that's what looks like needs to happen," she said. "And you can do the same: just give me as much notice as you can."

"Awesome, thanks!" I said.

"I'm guessing that that's what you were thinking of when you asked for my schedule?" she asked.

Blushing, I nodded.

"Are you thinking about masturbation?"

I nodded again.

"Ah, don't worry about it. We share the same room, so I don't think we have to hide stuff like that. I mean, I will if you mind, but it's kind of silly."

"I don't mind," I said quickly.

"Well, that's settled, then," she said.

Later that night, I started to hear her suspiciously rhythmic breathing again.

Fuck. She's masturbating again. —But she said it's OK. Did she really mean it?

My dick was rock hard in my boxers, and the sound of her panting was absolutely turning me on. Nothing ventured, nothing gained, right? I rolled over to my side, not facing her, and reached into my boxers. I didn't really want to masturbate like this, but this way, at least semen would get into my boxers and not my sheets if it got that far. I started stroking my thick dick, listening to her breathing, and her moans—

"Mike," she said in a very awake voice. I stopped jerking immediately.

"Yeah?" I said.

"I thought you were awake. Are you jerking off?"

"Yeah, I was. I thought you said it was OK," I said.

"It is OK," she said. "But if we're both jerking off anyway, do you wanna fuck?"

"What?"

"Do you want to have sex?"

"That's what I thought you said. You're sure it's OK?"

"Of course it's OK. I want your dick—unless you're not into that sort of thing."

"Right now?"

"When else?"

"Then heck yes!" I said.

She climbed out from under the blanket. She was wearing just a t-shirt, a little looser than the one she'd worn during the day, and she'd taken off her underwear. Her pubic hair was neatly trimmed, I saw as she crossed the dimly-lit room.

I tossed aside the blanket. I was only wearing boxers, and I arched my back to get them over my butt, then pulled them off my legs. She meanwhile tore off her shirt, tossed it onto her bed, and climbed onto my bed.

"I knew you'd have a great dick," she said, hovering over my crotch. Then she grabbed my thick dick with her soft hand and slowly lowered herself down.

I hissed as soon as I started to enter her. Her pussy was so soft, so warm, so wet—and so surprising. I'd never thought that my roommate would be so hot—or that I could fuck her! I felt as if I was winning the lottery.

She moaned as she sank onto my dick, and soon she was sitting all the way down, and I was balls deep. Her body was so tiny it seemed incredible that my dick fit inside her. "Damn, you're thick," she said.

"And you're so tight," I panted.

She started rocking, grinding on me, and again I felt like I was winning the lottery as she engulfed my dick, her boobs bouncing and jiggling. I pushed into her just a little, as much as I could from that position, while she panted and moaned.

But soon I wanted more. With a growl, I sat up, pulled her to the side, then pushed her down onto her back, still in her. This was exactly the missionary I'd imagined: her legs spread wide on my bed around my legs, my dick plunging deep into her pussy. With the leverage I got from having my knees on the bed, I plunged deeper into her, harder. I felt as if I was pushing aside several organs with my dick with each thrust. She moaned and panted. "Yeah, fuck me like this," she said. I couldn't believe that I got to claim my sexy roommate like this, and I could hardly see anything other than her perky boobs and her cute face. Even in the dim light, her face looked sweaty, cute, and somehow hungry. I couldn't find words. I growled as I drove my dick into her and she panted, again and again.

Soon I felt a happy dizziness swirling inside me. "I'm gonna cum," I panted. "Can I cum inside you?"

"Yeah, cum for me," she panted.

I growled again as I sank my cock deep into her pussy again, and I panted, "I'm cumming!" Unbelievable dizziness washed over my body as semen welled up deep inside my crotch. My cock pulsed and pulsed, pumping hot semen deep into her, each pulse an explosion of sensation that made me shudder. I might have been laughing or sobbing. I collapsed onto her soft chest as my cock kept pulsing, spurting semen into her very wet pussy, again and again, with the best sensation I'd ever felt.

Finally, the pulses died down, and I just lay on her chest, panting, still inside of her.

"That was incredible," I said after a while.

"Was?" she said.

"What do you mean 'was'?" I said.

"I'm not done," she said. "Will you go down on me?"

"Of course," I said. I almost couldn't believe that we hadn't shared an orgasm; it had felt as if the orgasm had filled the whole room. But it had felt so good that of course I wanted her to feel something like that too.

I pulled out and slowly crawled down her slim, beautiful body, and lay down between her legs, which she still spread wide. Even in the dim light, I could see that her pussy was gaping, brimming with thick semen.

I did this,

I thought with pride. I licked her entrance and swallowed my semen. It was thick and a little salty. I licked all around everything I saw, her inner labia, her outer labia, that weird place between her entrance and her clit, and her clit. She shuddered when I got to her clit. I again toured everything with my tongue, licking up more of my semen that was drooling out, and finally making it to her clit again. "Yeah, just like that," she said, panting. I lay my head down and let my tongue stay in contact with her clit, not stopping between one lick and the next, and she shuddered. "Don't stop," she panted. Then "Yeah, just like that," and then she was moaning again as her body shuddered under my mouth, spasming again and again.

I lay there for a few moments more, just resting my head on her crotch.

She sat up.

"I'll sleep in my own bed," she said. "But thank you for that."

"Thank you," I said. "Will—will we have sex again?"

"Any time! I'm lucky I've got you as a roommate," she said as she got up.

"No, I think I'm the lucky one," I said.

"Maybe we're both lucky," she said as she settled back into her own bed. "But let's not change rooms."

"Let's not," I agreed.

I drifted into a very satisfied sleep. I never thought I'd room with a hot girl like this due to some administrator's mistake, but some mistakes shouldn't be corrected.
