My Sister-in-Law Asked Me to Take Her Virginity That Morning

It was three in the morning and Sofía was covering my mouth with her hand to muffle my moans.

Each thrust brought me closer to the edge. I drove my hips hard, burying myself in her, feeling how her body tightened against mine in the dim light of the room. My wife arched her back and dug her nails into my bare shoulder.

I jerked my head aside, pulled her hand away from my mouth, and let out a long groan when I came inside her. Sofía took my load with a smile, still breathless, and whispered in my ear.

—Shhh, I told you to be quiet. Camila is in the other room and she’s going to hear us.

—Sorry —I murmured, catching my breath—. You know I can’t hold back when I come.

—I know. And I love it. You fucked me beautifully.

She curled up against my chest and fell asleep a few minutes later. I stayed awake for a while staring at the ceiling, listening to the house creak, wondering whether her sister had really heard us.

The next morning we had breakfast together. Sofía got ready to go to the office and I, since I was working from home that week, set up my workspace at the dining table: laptop, thermos, mate. I kissed her goodbye at the door, told her to take care of herself, and sat down to check my emails.

An hour later I heard the guest room door. Camila appeared in the living room shuffling her feet, her brown hair tousled, wearing a long T-shirt that barely covered her thighs. She made herself a tea and came over to the table.

—Hi, Mateo. Good morning.

—Morning, Cami. How did you sleep?

—Fine. Although I didn’t get much sleep last night —she said, and the smile with which she said it was anything but innocent.

I raised my eyebrows, trying to keep my tone casual.

—Oh, that sucks. What happened?

—Nothing. Just that there were a lot of noises coming from your room.

I felt the blood rush to my face. I looked down at the keyboard, pretending to concentrate.

—How embarrassing, Cami. Sorry, really, I didn’t realize.

—And the night before that too —she added, biting her lip.

—Uh… I don’t know what to tell you.

—Nothing. Just, poor my sister, having to go to work without sleep. Though I guess she’s happy.

She laughed softly and I laughed too, more from nerves than anything else.

—I promise I’ll be more careful —I told her.

—Please. I’ve gone two nights without getting a wink. I’m already curious about what you do.

She said it in a low voice, almost to herself, and stood up. She went over to the living room couch with the cup in her hand, settled on her side, and covered her legs with a cushion.

***

I tried to keep working. I really did. But her last words kept circling in my head and every two minutes I’d look up from the screen to watch her.

Camila had just turned eighteen. She was a skinny girl with long legs, light brown hair full of curls falling over her shoulders. The old T-shirt outlined her small breasts, and her nipples showed through the fabric. Her legs, covered by stockings that reached halfway up her thighs, were tucked against the cushion in a gesture that looked innocent until you noticed how she was pressing them.

She had her phone in one hand. The other had disappeared under the cushion.

Don’t be dirty-minded. She’s your wife’s sister.

But every so often she looked at me, and each time she did her legs squeezed a little tighter around the cushion. Her breathing sped up. I was getting an erection that no longer fit in my pajama pants.

I stood up.

—I’m going to make some coffee. Want one?

—Sure.

I came back with two cups. I set hers on the little table and sat at the far end of the couch. She sat up and took a sip, slowly, watching me over the rim.

—I hope this wakes me up —she said.

—It wasn’t that bad. We didn’t make a scene.

—And who told you I wasn’t awake because of the scene?

—You did. You told me the noises woke you up.

—Yeah, they woke me up. But I couldn’t sleep thinking about what you were doing.

She set the cup on the little table. She turned toward me, crossing her legs on the couch, and looked me straight in the eye.

—What would you be doing? What all couples do, I guess.

—I guess —I repeated.

—Honestly, I don’t know. Could you show me?

A shiver ran down my back. I swallowed. The words came out in fits and starts.

—Wait, Cami. Are you asking me to…? You’re my wife’s sister.

—I’m only asking you to help me. Last night and the night before, after hearing you, I couldn’t sleep. But not because of the noises. I kept touching myself over and over and it wasn’t enough. Just now I was touching myself while you were watching me. —She paused and lowered her voice—. You’re going to think I’m crazy. But I’ve never been with a guy. I mean, with one, yes, once. We were kissing and I put my hand down his pants. He pulled it away and ran off. I felt like an idiot.

—He probably got scared —I told her—. Or he came and didn’t want you to notice.

—Whatever. But I need someone who knows what he’s doing.

She stood up. Without taking her eyes off me, she grabbed the hem of her T-shirt and pulled it over her head.

She stood in front of me with her small breasts bare, pink nipples hardened by the cold of the living room, white panties with a faded design, and thigh-high stockings. Her pale skin, almost luminous, against the dark back of the couch.

—Will you help me? —she asked.

I could not breathe. My erection was throbbing painfully under my pants.

I stood slowly. She never took her eyes off me, fixed on the bulge in my pajama pants.

—Do you want to see it? —I asked her.

She nodded, biting her lip.

I pulled down my pants and boxers in one motion. Her face lit up when she saw me. I took hold of myself and pulled the foreskin back, exposing the glans.

—Do you want to touch it?

She reached out. She touched me as if afraid I’d bite her.

—Easy —I told her—. Grab it firmly. Touch the balls too. Wasn’t that what you wanted to know?

Something in my tone got under her skin. She grabbed me more decisively, started moving her hand up and down gently, studying every inch as if she were memorizing it.

—You don’t have hair? —she said, surprised.

—Your sister likes it like this.

She kept masturbating me with a concentration that undid me. I asked if she wanted to try it with her mouth and she made a disgusted face that made me laugh.

—Relax. It’s a matter of taste.

But almost without thinking, she leaned in, brushed her lips over my cock as if getting to know it, and surprised me when she took my balls into her mouth. She sucked them with her tongue, played with them, never letting go. I took her hand and showed her how to jerk me off at the same time. She learned fast.

After a while she sat up. She looked up at me with shining eyes.

—Do you want to put it in me?

I was no longer myself. My head was somewhere else. I lifted her by the waist —she weighed next to nothing— and sat her on the couch.

—Are you sure? You said you’ve never been with anyone.

—I told you, only the one who ran off.

—Okay.

I knelt between her legs. I pulled down her panties and let them fall to the floor. In front of me was a pink vulva, with just a hint of pubic hair, the lips closed in a thin line.

I parted her legs gently. She was trembling, completely tense.

—Relax —I whispered—. We’ll go as far as you want. But if you stay rigid, you won’t enjoy it.

She took a breath and threw her head back. I placed my thumb on her clit and began moving it in slow circles. I parted her lips with two fingers, found that little bud peeking out like a pearl, and kissed her nipples while I caressed her.

She was soaking wet. The arousal from the previous two nights was all there, pent up. I slid my index finger in very slowly, without stopping stroking her clit or licking her breasts. Her breathing quickened within seconds. She squeezed her legs around my hand and let out a soft little “oh, yes” that was barely audible.

She stayed still for a while, catching her breath. I kept brushing my lips over her nipples, waiting.

—Did you like that? —I asked her.

—Yes. It’s way better than when I touch myself.

—Just so you know, the best part is still coming.

She looked at me with a mix of fear and desire and nodded.

I spread her legs and lowered my face to her sex. I took my time. I ran my tongue slowly between her lips, gathering the wetness, spreading it around. Her clit was already swollen and clearly visible. I began to suck it carefully, alternating with the tip of my tongue inside her.

At first Camila moaned softly. Then not so softly. Then she stopped holding back. I grabbed her thighs with both hands to keep her open and worked her until she came a second time, this one with a long moan and her whole body arching.

I sat up. She looked at me hard, came closer, and took me in her hand. She jerked me for a while, fascinated by the fluid that kept leaking from my tip, and she dared to put me in her mouth just enough to taste it. Her curiosity —the way she was discovering everything for the first time— had me right on the edge.

—I want you to make me scream like you do with my sister —she told me, letting go of me.

I swallowed. The moment had come.

***

I knelt in front of her again, placed the tip against her vulva, and lubed it with saliva. I started pressing in very slowly. Her body resisted, then yielded, then resisted again. The glans forced its way between her lips and stopped there, wedged in, unable to go farther.

She was biting her own hand.

—Does it hurt a lot? Should I take it out?

—Yes. No. Keep going, keep going.

I pressed a little more and felt her give way. Camila let out a muffled cry and dug her nails into my back. I stayed still, kissing her breasts, waiting for her to get used to it.

—It burns —she said.

—That’s normal. It’ll pass.

I pulled out carefully. There was a thin thread of blood. I grabbed the T-shirt she had taken off earlier, gently cleaned her between her legs, cleaned myself, lubed up again with saliva, and went back in.

This time it was easier. I moved slowly, giving her time. She was still tense, but little by little her body loosened. The tightness gripped me so hard I had to make a huge effort not to finish right then and there.

—Do you want to get on top? —I asked, standing up.

She nodded eagerly.

I threw the cushions onto the floor and lay down on my back. I held my cock while she got herself into position, taking me in her hand, lowering herself millimeter by millimeter until she had all of me inside. Then she started moving.

The moans turned into screams within seconds. No filter. No shame. With her hands on my chest, her hips moving faster and faster, her small breasts bouncing softly, her face twisted with pleasure.

—Turn around —I told her when I felt I couldn’t take it anymore—. Get on all fours.

—What?

—Like a doggy style.

She did it, still unsure. I grabbed her by the waist and thrust in all at once. She let out a deep moan that made me lose control. I fucked her hard, but careful not to get carried away, knowing it was her first time.

The orgasm hit me sooner than I expected. I felt the spurts emptying inside her. Camila experienced her first internal finish that way, with a long cry that was probably heard in the apartment next door. Her legs trembled, she collapsed onto the rug, and stayed there, gasping, with an idiotic smile on her face.

***

She got up after a while and went to shower. When she came back, wrapped in a towel, she told me,

—I’m definitely sleeping tonight. I never imagined it would be this nice.

—I appreciate you choosing me —I told her—. And this is only just beginning. You’re going to discover much more intense things.

That afternoon Sofía came back from work. While we were drinking mate, she asked me about her sister.

—She’s sleeping —I told her.

My wife looked at me over the bombilla, smiled sideways, and said,

—Ah. That lesson was tough.

I was left speechless.

But that’s another story.
