My boyfriend and my best friend [cheating] [MF] part two

**See here for [part one](https://www.reddit.com/r/Erotica/comments/i6e7oy/my_boyfriend_and_my_best_friend_cheating_mf_part/?ref=share&ref_source=link).**

I stood at the top of the stairs, frozen.

I could see from the light from the TV that they were in the middle of the living room, right on the floor, next to the air mattress. Rayna was on all fours, tits slapping against each other as she took his cock from behind.

I watched as Alex pumped into her rhythmically, the way he’d fuck me. Her brows were furrowed and her mouth formed an ‘O’, a look that I had only seen in porn—and the mirror when Alex fucked me in on the bathroom sink. He had his hands on her hips and a look of concentration on his face as he fucked her. She was panting, trying not to make a sound, but he was fucking her hard. She moaned loudly.

I felt my knees go weak. He put a hand over her mouth to keep her quiet and automatically she reached between her legs to rub herself as he fucked her harder.

I couldn’t believe what I was watching, but I was stuck there, silent as a mouse, watching my best friend get railed by my boyfriend. I didn’t know what to do—should I storm in? Should I go back to the room and regroup, figure out what to do? I worried that if I went back, I’d make noise and alert them both. She lied to me, and he didn’t even have the balls to tell me the truth about their kiss either.

Fuck. I could not stop staring at her, tits swaying and ass rippling as he slammed into her. He let go to cup her tits, squeezing roughly and pulling her up to him. He never did that to me—I was a B cup at best. Hers barely fit in his hands and spilled out of his palm. She whined as he muttered something in her ear. I couldn’t hear what he said, but his voice was low and rumbling. He must have told her to keep it down because she bit her lip to stay quiet.

He started rubbing her clit and instinctively, I reached down and brushed my fingers against my pussy. I wasn’t getting turned on, was I? I slipped a finger to part my lips and almost gasped—I was dripping wet. I swallowed down the lump in my throat. Oh, no. I couldn’t believe it, but I still couldn’t look away. I tried to move but I just watched. I looked down at my small tits, my nipples were rock hard. I bit my lip. Did I like this?

The blue light from the TV highlighted everything— both Alex and Rayna’s caramel skin, the way her full breasts bounced, the soft line down her stomach, her pink clit, his cock pumping in and out of her, his arms around her, the sweat on his forehead. They looked so lost in the moment, moving together, desperate for release.

I watched as he pushed her back down and she was down on her elbows, her nipples rubbing against the rug. I could tell she was close, she pushed back on him desperately and started to shake. He fucked her through her orgasm and put his hand over her mouth, muffling her moans.

I saw the look on my boyfriend’s face and I knew he was close. I had to go. I held my breath and pressed myself against the wall, slinking down the hallway and slipping into the room, careful to make sure the door didn’t creak as I shut it.

The last thing I heard before I clicked it shut was Alex’s gruff, panicked whisper, “Where do you want me to cum?”

Neither Alex nor Rayna knew that I had been watching. Alex came to bed after what felt like hours. I lay facing away from him and pretended to be asleep. He settled in under the sheets with me and wrapped his arm around me, his chest pressed against my back, knees lined up behind mine, like nothing was wrong. It wasn’t long until I could hear him snoring lightly against my ear. I stared at the light outside the window, thinking about Rayna in the room under us, fast asleep just like Alex was.

I couldn’t sleep. I was angry, betrayed, and confused—all I could think about was how wet my pussy was while watching them fuck.
