At my brother's party, I believed the door was locked

It’s loud downstairs. Really loud. It’s Friday, and my girlfriend is back at work, and my brother and his friends are bustling around downstairs. I hate that we have to share this house. I only moved in to save money. He works a lot, so it’s not so bad.

I get a notification from my girlfriend. “Sorry about tonight. I know we had plans, but I have to stay at this job.” She posts a video of one of your previous lovemaking sessions. I didn’t want to record it. I was afraid I’d expose myself or something, but tonight I’m glad we recorded it. She licks my breast, the left one with the nipple clamp. I hear my moans, and she smiles devilishly. She adds, “That’s what I’m thinking.” I’ll be home after the bar closes, and we can continue this. I check my phone; damn, it’s only 8:00 PM. I watch the video of me smiling. My body starts to feel warm. Damn, I can’t wait. I scan the hallway and close the door. I want to make sure no one’s waiting for the bathroom next to my room.

I take off my shorts and jump onto the bed. I look at the recording, and as it plays, I slowly start touching my inner thighs. I gently run my nails over the skin. A gentle, light scratch. I close my eyes and put my headphones in. I turn up the volume and listen to the sounds. I focus on the sound of my own voice. Hearing myself arouses me even more. I slide my hand over my mound and simply press. I simply rub my slit through my panties. I lose myself in the moment. I feel the wetness building as I begin to match my movements with hers on the recording.

And I start moaning. I feel myself getting close. My girlfriend squeezes my pussy lips and rolls my clit between them. She taught me this, and I don’t know if I could have reached orgasm without it. I can’t get a good grip, so I shove my hand into my panties. I squirt. I continue rolling my clit between my labia. I moan louder. “Fuck!” I honestly don’t know how loud I’m saying. I roll onto my stomach and rub my hands together, lifting my buttocks slightly. Just enough to give my hands room to work. And I speed up. I lose myself in my own passion.

My panties are starting to get in the way. I roll over to take them off. I hook my thumbs into the waistband and quickly pull them down. I grab them and toss them toward the laundry basket. I look up and see one of my brother’s friends watching me from the doorway. I forgot to lock the door. I panic, pull my legs up, and wrap my arms around them.

“GET OUT, WHAT ARE YOU DOING, WHY ARE YOU HERE!” I scream, all at once.

“Hey, I was just looking for the bathroom. I opened the door and saw you.”

“That still doesn’t answer my question. What are you, some kind of pervert?” I frantically search for something to cover myself with.

He stammers, “I’m NOT! I just, I mean, I’m not, you were just, well, loud.” I sit cross-legged and stare at him. I notice he’s incredibly dizzy, like most of my brother’s friends. They’re accountants and engineers from his company. All in their twenties.

“Uh, did you come?”

“WHAT!!!”

He looks away. “I’m sorry.” He looks like a lost puppy. “I’ve seen women come in porn, but never in real life.” I feel a little sorry for him.

“STILL, privacy, you know.” He avoids eye contact. “I guess it makes sense. I didn’t know you were a virgin. Whatever you should—”

“I’M NOT!” he blurted out. His face turns red. “I have a girlfriend, but I don’t know how to make her cum. She never makes the sounds you do. You don’t have to stop because I walked into the room.”

“WHAT!!! NO!! That’s your problem, not mine. Just close the damn door!”

“I’m sorry, I just really like her and I think I’m terrible at sex and stuff. My friends say how much they turn their girlfriends on. I know I don’t, so she’ll probably leave.”

Finally, I find a blanket on the edge of the bed and cover myself. “Look, sex is NOT something most women base their relationships on. Unless you’re REALLY terrible.”

“I’m really terrible. I can’t last long. I definitely don’t have the penis I see online. I’m not rich yet, so why would she stay?” Okay, this is getting weird, but I feel a little sorry for him. And most of all, for her.

“Okay, that’s a good lesson.” I can’t believe I’m fucking doing this. I pull out my phone and show him the video. “That’s how it’s done.” He’s just old.

“Close the damn door and lock it this time.” He snaps back to reality and closes the door. Fuck, the video of my girlfriend is turning me on so much right now. “Come here,” I say. “Sit on the end of the bed.” I turn on the TV and connect it to my phone. “Just watch,” I tell him. He’s sitting on the end of my bed. He’s just staring at the screen.

I start explaining what’s happening in the video. “Look, she’s just gently running her tongue up and down her inner thigh. Gently and slowly. She’s keeping her tongue wet, leaving a trail.” I just stare at the back of his head…
