I stood up from the lounge chair and told Sarah I needed the bathroom. She smiled without really looking at me and went back to talking with Cindy. My legs felt heavy as I crossed the concrete. The house was cool when I stepped inside. I was halfway down the hall when I heard Ryan’s voice, low and rough, coming from the living room.
“Fuck, that feels great, babe.”
I froze in my tracks. My first clear thought was to keep walking. My second thought was that if I kept walking, I would spend the rest of the afternoon wondering what I had almost seen. I moved toward the sound barefoot, staying close to the wall. When I reached the corner, I looked around it, and the shame hit before the view fully registered. I was standing in my friend’s house, hidden, about to watch them. I told myself I would look for one second and leave. I already knew that was a lie.
Ryan stood with his back mostly to me. Roxie was on her knees in front of him. Her bikini top had been pulled down under her breasts so they were completely bare. One hand was between her own legs; the other was up by Ryan’s crotch, and even though my view was obscured, it was obvious what she was doing from the noise she was making and the motion of her head as she moved back and forth on his cock. She looked flushed and focused. Ryan looked down at her and smiled.
“You’re so fucking good at that, Rox,” he said. “Fuck you are a sexy bitch.”
My face burned. It had been well over a year since Sarah had gone down on me, maybe two, and even then she had stopped the second she felt me getting close. Watching Roxie—gorgeous, confident, her lipstick already smeared around her mouth—take him like she wanted to do it made my cock harden so fast it pressed painfully against my trunks. I hated how quickly it happened and that the sounds coming from her mouth on him were already making me leak. I told myself I was a piece of shit for standing there and watching, but I didn’t move.
Roxie pulled off with a wet sound and stroked him with both hands. Her lips were red and swollen. She looked up at him.
“I need you to fuck me,” she said. “Right now.”
She leaned in again and took one of his balls into her mouth. The angle was not perfect, but I could see enough. She sucked, then switched to the other. Ryan’s head tipped back.
“Jesus, Rox. You know exactly what you’re doing.”
A soft pop sounded when she let one slip free. She looked up at him, mouth wet.
“Stop talking and make me feel good.”
Ryan bent, caught her under the arms, and lifted her. He turned her and bent her over the couch arm. Roxie reached back, untied her thong strings, and let it fall. She looked over her shoulder, reached back with both hands, and spread herself wide open. I could see everything from where I was: the tight ring of her asshole, the swollen, glistening lips of her pussy, already wet and parted. My cock throbbed hard enough that I had to shift my weight. I thought about Sarah. She had never once done this for me. She had never spread herself and asked like that. The comparison landed like a fist, and I still didn’t look away.
“Fuck me,” she pleaded with him. “Don’t go slow.”
Ryan stepped in, kicked her feet wider, and drove into her in one hard stroke. Roxie gasped, then moaned, long and low. The sound of him bottoming out was wet and heavy. He pulled back and slammed in again. The couch creaked under them. Her breasts swung with every thrust.
“Yes—right there—god, Ryan, don’t you dare stop—”
He kept a hard, steady rhythm, hands locked on her hips. She pushed back to meet him. The wet slap of skin got louder. I could see how wet she was every time he pulled back as her juices created a wet streak down the inside of her thigh. I had never heard Sarah make sounds like that, and she almost never pushed back. The thought made my stomach tight and my cock harder at the same time. I wondered what it would feel like to be the one making those sounds come out of someone. I wondered if Sarah would ever sound like that for me.
“You love this cock, don’t you?” he said.
“Yes—fuck—yes—harder—give it to me harder—”
Her voice climbed. Her legs started to shake. One hand left the couch and clawed at the cushion. She came hard, body jerking, a broken cry of his name muffled against her arm. Her thighs quivered. He did not slow down. He just kept pounding into her from behind. I stood there with my hand braced on the wall and felt my own cock twitch in time with the wet sounds. I was disgusted with myself. I was also harder than I had been in months.
Ryan’s hand came down hard on her ass. The crack was sharp and loud. She yelped.
“Keep that whore mouth quiet or everyone outside is going to hear you.”
I flinched at the word. Roxie did not. She pushed back harder and looked over her shoulder, eyes glassy, face flushed.
“Then fuck your whore wife,” she said, voice low and wrecked. “Pound me. Make me cum again like the dirty slut I am.”
He spanked her again, harder, once on each cheek. She yelped both times but kept moving on his cock. Her ass was already turning red. The handprints stood out clearly. I could not believe she was encouraging it. I could not believe how much it was affecting me.
“I told you to keep the noise down,” he said. “If you don’t, I’m going to shove this cock in your ass and give you something to really scream about.”
