My Friend Taught Me What He Couldn’t Give Me

Camila and Sofía had just turned nineteen. They had been inseparable since they were fourteen: they told each other absolutely everything, from the complications of the last year of school to the most intimate details with boys. Camila had been dating Lautaro for almost a year, a college guy who seemed very mature when they texted, but who in bed was still a disaster of rushing and premature endings. Sofía, on the other hand, preferred not to tie herself to anyone. “What for?” she always repeated. “They end up getting bored anyway, or doing something stupid.”

They were night and day in terms of bodies. Camila was tall and very slender: one meter seventy-two, a very narrow waist, small but firm breasts, round perky ass, legs so long they seemed to go on forever. Sofía, on the other hand, was all curves: wide hips, a big soft ass that swayed with every step, a soft belly with that delicious roundness, abundant breasts that overflowed any bra, and meaty thighs that brushed together when she walked.

They loved each other madly, and although they had never crossed a line beyond long hugs and the occasional casual touch on the sofa, lately they had been talking too much about “getting better” for when they were with men.

That Friday afternoon Sofía’s parents had left the city for the long weekend. The house was empty, the blinds half-drawn, the smell of freshly brewed coffee and the vanilla candles Camila always carried in her backpack. The two of them were sprawled on Sofía’s double bed, in underwear and oversized T-shirts, with the laptop open watching a video titled “how to stimulate the prostate to drive him crazy.”

Camila sighed and bit her thumbnail.

—I swear I can’t take it anymore, Sofi. Lautaro comes in two minutes, three at most. I told him a thousand times to try something different, to be brave, to let me put a finger in him from behind… and he always comes out with that “that’s for faggots” bullshit. And I’m thinking: if you knew what it feels like when it’s done right…

Sofía let out a deep, rough laugh, one of hers.

—Does it freak him out? If you shoved the whole cock in, he’d ask for three fingers and for you to say “come here” with them inside. Men are very macho until it’s time to really open up.

A brief silence. They looked at each other sideways. Camila turned red all the way to her ears.

—And if… we tried it ourselves? —she blurted out, almost out of breath—. Just to learn. To know what it feels like, how to do it slowly, how not to hurt. And then drive them crazy.

Sofía propped herself up on her elbows, eyes wide.

—Are you serious, skinny? You want us to buy a harness and fuck each other just to “practice”?

Camila covered her face with her hands.

—I don’t know… saying it like that sounds kind of crazy. But we trust each other. There won’t be any weird lust or drama. Just learning. And if we regret it afterward, we stop and that’s it.

Sofía stayed silent for a long while, staring at the ceiling. Camila counted the seconds in her head.

—I don’t know, Cami. It makes me uneasy. What if we look at each other differently afterward? What if one of us gets too turned on and the other feels uncomfortable? What if tomorrow we can’t look each other in the face without dying of embarrassment?

Camila took a deep breath and sat facing her, crossing her legs.

—If we get embarrassed, we talk and that’s it. But Sofi, I’ve spent months thinking about how to drive Lautaro crazy and I can’t think of anything new. And you always say men have to be given it from behind to make them surrender. Wouldn’t it be… actually useful?

Sofía snorted, half laugh, half nerves.

—“Useful,” she says. Fine. But with clear rules. No kissing on the mouth. No mushy words. Just practice. And if one of us says “stop,” we stop immediately. Deal?

Camila nodded slowly. Her heart was pounding against her throat.

—Deal.

They opened the delivery app. It took them almost twenty minutes to decide: a basic black harness and a dark purple dildo, veined, realistic, about eighteen centimeters long, thick but not exaggerated. “Best seller in the intermediate category,” the description said. They paid with the phone and chose express delivery.

When the courier arrived, Sofía ran downstairs in a T-shirt and leggings, paid with her face burning, and came back up clutching the bag against her chest.

—I swear the guy looked at me like he knew exactly what’s inside here —she murmured, closing the door with her elbow.

They emptied the contents onto the bed. The harness smelled like new rubber, clean, almost medicinal. The dildo, out of the packaging, was more imposing than it had seemed in the photos. The two of them looked at each other and burst into silly laughter.

—Who’s wearing it? —Camila asked.

Sofía shrugged.

—We’ll draw straws. Rock, paper, scissors. The loser puts it on and fucks. The other one takes it.

They played six rounds because they couldn’t stop laughing and accidentally cheating. In the end Sofía won.

—It’s me —she said, laughing but with nerves trembling in her voice—. Okay. But first we breathe. Drink something, calm down.

They made themselves two herbal teas each, sitting at the kitchen table in silence. Camila couldn’t stop moving her leg under the table. Sofía bit the inside of her cheek.

—Do we keep going or call it off? —Sofía asked at last.

Camila took a deep breath.

—We keep going. But slowly. And if it upsets us, we stop with no drama.

They went back to the bedroom. Sofía yanked off her underwear and strapped the harness on over her wide hips. It looked imposing on her; the purple dildo pointed forward like an obscene promise. Camila took off her clothes too, leaving only her sports bra. She lay face down on the bed, legs slightly apart.

Sofía knelt behind her, pouring lubricant into her palm.

—Listen to me, skinny —she said in a low, firm voice as she gently spread her cheeks—. You’re going to be a very brave girl today. I’m going to open you up slowly, I’m going to get all the way in, and you’re going to learn to enjoy it. Understand?

Camila buried her face in the pillow and nodded.

—Y-yes…

Sofía started by coating her well with two fingers, going in and out slowly. Camila shivered and arched her back a little.

—Look at you. You’re already soaking, baby. You get so hot thinking your friend is going to fuck you, don’t you?

Camila let out a soft moan against the pillowcase.

—I don’t know… it makes me uneasy… but yes…

—Then relax and let me in. Take a deep breath. That’s it. Good girl.

She placed the tip of the dildo and pushed slowly. The head slid in with a soft sound, almost a little pop. Camila let out a long moan, half surprise, half relief.

—You’re doing perfect —Sofía whispered, stroking her back with an open palm—. Keep breathing. Now comes the best part.

She went in inch by inch, pausing every time she felt resistance. When she was all the way in, pelvis against ass, the two of them froze for an instant, panting in the dim light.

—You’re so tight, skinny —Sofía murmured, her voice rough—. Do you like feeling me this deep?

Camila pushed back a little, nodding with her forehead resting on the pillow.

—Move… slowly… please…

Sofía started pumping slowly, sliding almost all the way out and then back in until she hit bottom. The wet sound of the lubricant filled the room.

—That’s it, baby. Push back when I push in. Very good. You’re being a perfect student.

After a few minutes, Sofía leaned over her ear.

—Want to try another position, brave girl? Tell me what you feel like.

Camila lifted her head, red to the neck.

—I want… to see your face. Put me on my back.

They changed positions. Camila on her back, legs open and bent against her chest. Sofía between her thighs, supported on her forearms. She entered again slowly, staring straight into her eyes.

—Look at me, skinny. Look at how it goes all the way in. See what I’m doing to you? You’re going to learn to fuck your boyfriend this well.

Camila was moaning louder, digging her nails into Sofía’s forearms.

—Faster… please, Sofi… harder…

Sofía quickened the pace, deep and steady, never breaking eye contact.

—That’s it. You like it, don’t you? You like being taken. Come on, cum for me, baby.

I don’t believe this. My best friend. This is happening with my best friend.

Then they tried again on all fours, but this time with Camila standing, bent over the edge of the bed. Sofía behind her, gripping her narrow hips, thrusting with controlled force.

—Push back, skinny. Show me how hot you are. What a gorgeous ass you’ve got.

Camila pushed back, moaning almost uncontrollably, her hands clutching the edge of the mattress.

—I feel it all the way in my stomach… don’t stop…

Finally, Camila sat astride Sofía, who lay on her back on the bed. She controlled the depth, going up and down slowly at first, then faster. Sofía’s hands held her ass, setting the rhythm from below.

—Look at you. Riding me like a champion —Sofía gasped, her eyes fixed on the small breasts bouncing over her body—. Rub your clit against the base. There. Very good. You’re going to cum hard, right?

Camila sped up, trembling all over. Her eyes were closed and her lips parted.

—I’m cumming… I’m cumming… Sofi!

She tensed, a shudder running through her legs, and a hot gush wet Sofía’s cunt. She screamed her name with a broken voice and collapsed over her, panting against her neck.

Sofía didn’t stop. She thrust upward a couple more times, grinding against the base of the harness until she felt her own orgasm climb without warning, dull and deep.

—I’m cumming… with you… fuck…

They both ended up collapsed, sweaty, panting, with the dildo still inside. Several minutes passed without either of them speaking, just breathing. Outside it was starting to get dark, and the orange light of sunset came in striped through the blinds.

Camila was the first to break the silence, in a small voice.

—Did it seem… really weird to you?

Sofía stroked her hair, chuckling softly against her temple.

—At first, yes, a lot. But after that… fuck, it was incredible. And you were a perfect student. What about you?

Camila smiled, tired but happy, still resting on her chest.

—At first I was terrified. I thought we’d feel bad afterward. But it was good. Really good. And actually useful.

Sofía gave her a soft kiss on the forehead. Tender. Clean. Like the thousands of kisses they had always given each other, except now something different weighed beneath their lips.

—Well. Now you know how it’s done. Poor Lautaro.

Camila burst out laughing against her neck.

—Poor Lautaro, nothing. He’s going to learn, even if I have to teach him with my finger and the patience I’ve got left now.

Sofía held her a little tighter and closed her eyes, tracing a smile that Camila never got to see.

—And if he doesn’t learn, you know where to find me.

Camila didn’t answer. She stayed very still, listening to the steady beat under her cheek, thinking that that phrase was going to keep turning over in her head much longer than she would want to admit.
