"Didn't expect to find you like this." Rick was standing in our apartment's open door, staring at me. I was sitting on the living room couch with my blue jeans and briefs bunched around my ankles, slowly stroking my stiff dick.
Rick already had a bulge in his jeans. It grew bigger as he looked me over. "What got you so turned on?"
"Close the door." I turned back to the big flatscreen.
Rick closed the door and sat down on the couch beside me, alternating between watching the flatscreen and my hand sliding over my long hard cock. "What the hell is this?"
"What's it look like?" A young woman was lying on a bed with her long light brown hair flowing over the pillow, fondling her big breasts while pinching and twisting her swollen tan nipples.
"Jesus!" Rick half-rose to his feet. "It's Kathy!" He looked at me, then back at the flatscreen. The bulge in his pants was bigger than ever. "Where'd you get this?"
"It was on Bobby's phone." Bobby and Kathy had keys to our apartment. "She stopped by while we were in class. Left a bottle of wine and a note. Said she and Kathy were coming over . . . " The clock beside the flatscreen read 6:45 PM. " . . . in about an hour. For a little party."
"'Little party' huh? Sounds promising."
"Yep." It was Friday and we didn't have any exams or homework to worry about. "Guess it's gonna be a wild weekend."
Rick and I exchanged lewd grins. "And her phone?" he asked.
"Found it on the kitchen counter, on top of the note." I grabbed the remote and pushed buttons to restart the video. "When I touched it, this video came up. I watched it for a few minutes, then made a copy."
"Are you recording?" Kathy asked from the screen. We couldn't hear the answer. "This is weird." Kathy put her hands on her breasts. "But super hot, too."
"You're sure hot." It was Bobby's voice. She was holding the phone over Kathy's face and chest. "I'm already getting wet. Just from watching you."
Kathy giggled. "Everything gets you wet." She started playing with her breasts.
"We were right." Rick unzipped his jeans and took his cock out. "They are fucking."
"That bother you?" I reached over and gripped his swollen pole, running my thumb and index finger over its head. It was already leaking precum.
He grabbed my rod while staring at the screen. "Fuck no! This is sexy as hell."
The video passed the point where Rick had come in and the view moved down Kathy's body. Rick and I jacked each other off while we watched Bobby's hand guide a big purple vibrator in and out of Kathy's pussy. She rolled her hips, humping the softly-buzzing toy.
The view pulled back to show Kathy's body from her head to her knees as she screamed and thrashed. "Oh God!" she gasped. "This is so fuckin' good!"
"That's right, Baby," Bobby said. "Come for me. Good and hard." Wet sounds mixed with Kathy's cries as Bobby fucked her with the vibrator.
"This is wild," Rick said. "I never figured . . ." Kathy's screams grew even louder.
"Yeah," I answered. "Lesbian stuff is hot, anyway. But when it's your girlfriends . . ."
"Think Bobby forgot her phone?" Rick asked.
"Bobby's super organized. She never forgets anything." I was getting too close to coming. I caught Rick's hand to slow it down. "Especially not her phone."
"So she left it deliberately. And this video . . . "
"They wanted us to see this," I said. "They know that we know about them."
"Think they know about us?"
Someone knocked on the door. "Guess we're gonna find out."
I turned the video off. Rick and I stood up, stuffed our hard cocks back in our pants, and went to answer the door.
It was Bobby and Kathy, half an hour early. They stepped inside and closed the door behind them. They were both tall and athletic with big breasts. Kathy had blue eyes and shoulder-length brown hair. Bobby's eyes were green and her blond hair was collar-length.
They were wearing tiny blue jean cutoffs and sprayed-on tee-shirts with bare midriffs. Bobby's was blue and Kathy's was pink. Their nipples showed through the tightly-stretched cloth. "Fuck me now!" outfits.
"Hi boys," Kathy purred. She looked at the big bulges in our jeans and smiled.
Bobby was also smiling as she inspected our oversized packages. "Looks like you're glad to see us."
"Always," I answered. Rick just grinned.
Bobby stepped forward and hit me with a full body kiss, plastering her body against mine and flattening her breasts against my chest, grinding her crotch against the bulge in my jeans, and kissing me open-mouthed, with lots of tongue. Beside us, Kathy was dirty-kissing Rick.
Bobby caught my hands, and put them on her breasts. I caressed the firm flesh while pinching her pebble-hard nipples between my index and middle fingers. She ran her fingers over my hard-on. "Your big sexy gun," she whispered. "Already in firing position."
She rubbed my crotch harder. "Guess you liked the video."
"Uh . . ."
Bobby laughed softly and kissed me again, hard. "We could hear it from outside."
"Were you standing there listening?"
"Just for a couple minutes. We figured it would get you boys turned on." She squeezed my balls briefly, then went back to rubbing my stiff dick through my jeans. "Worked pretty good."
"Damn good." I ran my hands down her back and gripped her muscular buttocks. "What now?"
"This." Bobby unfastened my belt, unzipped my jeans, and pushed them down. She looked at my crotch and grinned. My swollen cock-head was sticking out of my low-cut briefs. She caught it between her thumb and index finger and pinched it gently, smearing the precum oozing from its tip.
