Silas Watches Adriana Take His Best Friend

I am twenty-eight years old, and I have wanted my stepsister since the month our parents got married. Adriana was twenty-four then. She still is. She had her own apartment and a job at a design studio before my mom ever said yes to her dad. I was already working full time and paying rent on this place. We met as adults. There was no shared childhood, no bunk beds, no old habit of thinking of her as family in any way that mattered. Stepsister was a word other people used. It never made my cock behave when she leaned across my kitchen counter and laughed.

She showed up after ten with a bottle of red and a look I couldn't name. We poured two glasses and left them almost full. I wanted my head clear for whatever she had come to say. She wanted the same. She turned the stem once, set the glass down, and stared at her hands.

"Don't hate me," she said.

"I won't."

"Benedict." My best friend's name sat in the air between us. Benedict is twenty-seven, the man I have trusted since we started at the same company, broad through the shoulders, quick to laugh, the friend you do not lie to. "I am wildly attracted to him. I have been since that cookout in your backyard. I want to sleep with him. I want him to fuck me, Silas. Hard. And I need to know if you would hate me for it. You're his closest friend. You're my stepbrother. I don't know which one of those I'm more afraid of breaking."

Jealousy went through me like a blade. Right behind it came the arousal, meaner and hotter, impossible to argue with. She wanted to give herself to the man closest to me, and every filthy picture that climbed into my head made my cock thicken against my pants. Years of wanting her and never touching her, and now she was asking me to bless the thing that would ruin me.

She watched my face like she was waiting for the floor to drop. I sat with my hands locked on my knees and felt the forbidden thing settle into my bones. Not just wanting her. Wanting to see her taken. Wanting the jealousy. Hating how good the jealousy felt. The wine sat untouched. My cock did not.

"Say something," she whispered.

"I don't hate you." My voice came out scraped raw. "I couldn't hate you if I tried."

Her eyes dropped to my lap. I saw the second she noticed. The bulge in my pants was obvious, nothing I could pass off as a shift in the cushion. Heat climbed her throat. I waited for her to grab her bag.

She didn't.

A filthy smile pulled at her mouth. "Silas. You're hard."

"Yeah."

"Because I said I want him to fuck me."

"Because you said it like you already know how."

She shifted closer. Not touching. Close enough that I caught her perfume and the heat under it. The wine stayed on the table. We were both sober, and she wanted me that way.

"You want the details," she said. "You want me to spell them while you suffer."

"If you're going to be tortured, you might as well hear every part," she said, and wet her lips. "I want Benedict's cock in my mouth first. I want to kneel and take him deep and make wet sounds you won't forget. Then I want to ride him until my pussy is stretched around his shaft and I'm dripping down his balls. I want it rough. I want his hands on my hips. I want to come with him inside me, and then I want him to pull out and cover my tits. And I want my stepbrother losing his mind because he has to watch."

My cock jerked. I didn't cover it.

She stared and her smile went wicked. "You're not even trying to hide it." She leaned in until her breath hit my jaw. "So if you're going to be tortured, watch in person. Sit in that chair. Don't touch me. Don't touch yourself until I say. Watch your best friend fuck your eager stepsister. Tell me you don't want that and I never bring it up again."

"I want it. I want to watch him fuck you. I won't touch you unless you ask. I need you to want me there."

"I do. I've wanted your face since I saw that bulge. Benedict has to agree. I'll call him. If he says no, we stop."

"I'm in."

My hands were shaking. Hers weren't. She looked at the tent in my pants like it was proof we had both been waiting for an excuse this filthy, and the shame I expected never showed up on her face. Only hunger. The same hunger chewing through me.

"Say it back," I told her, because I needed the words as much as she did.

"I want you there," she said. "I want my stepbrother's eyes on me while his best friend uses my pussy. That's the part that makes me wet."

She called from the kitchen. I heard her tell him what she wanted, that I would be in the chair, that he could say no. A pause. Then her pleased laugh. "Tonight. All of us sober. Come over."

She looked at me like a door had just opened on purpose. "He's coming. He wants you to see. Don't look away."

Benedict knocked twenty minutes later. He stepped into my living room in a henley and jeans, twenty-seven and solid, and looked at both of us like a man who had already made his choice and wanted it said out loud anyway.

"You're sure," he said to her. Then to me. "Both of you. Sober. Want this."

"Yes," Adriana said.

"Yes," I said. "I stay in the chair. I watch. I don't join unless she asks."

"She already told me the rules." His mouth tipped. "I want her. I want you to see it. If anybody taps out, we stop."

Nobody tapped out.

Adriana didn't waste the moment. She walked to him, kissed him once, hard, and dropped to her knees on my rug. Her fingers opened his jeans. His cock came out thick, heavy, already hard, and she made a hungry sound that went straight to my own. She wrapped her hand around him, stroked once, and looked past his hip straight at me.

"Watch, stepbrother," she said, and took him into her mouth.

I watched. Her lips stretched around Benedict's cock, glossy, obscene, and she sucked him with filthy enthusiasm, cheeks hollowing, spit shining on her chin. She bobbed slow at first, then deeper, gagging softly and going right back down like she loved the mess. Her eyes never left mine. Every time she pulled off to breathe she smiled at me, strings of spit connecting her mouth to his shaft, and then she swallowed him again.

"Fuck," Benedict groaned, one hand in her hair, not forcing, just holding. "She sucks cock like she was made for it."

She moaned around him, the vibration filthy, and pulled off with a wet pop. Saliva dripped onto her tits where her top had been shoved down. "I want him to see everything," she said, staring at me. "I want Silas to watch his best friend's cock wreck my throat and then wreck my pussy. Don't you dare be gentle with me, Benedict. And don't you dare close your eyes, Silas."

She stood, stripped her panties off, and left them on the floor between us like a flag. Then she pushed Benedict onto the couch, turned her back to him, and climbed on facing me. Reverse. Her knees sank into the cushions. She reached under herself, lined his thick shaft up, and sank.

I had the perfect view. Her pussy, pink and slick and swollen, stretched around his cock as she took him inch by inch. The lips clung and dragged. She whimpered, high and shameless, and kept going until she was seated, stuffed full, his balls pressed to her. I could see every detail. The way she fluttered. The shine. The obscene stretch of her around a cock that wasn't mine.

"Oh God," she gasped, and started to ride.

She rose until just the head held her open and dropped back down, ass smacking his thighs, pussy swallowing him again. She braced her hands on his knees and worked herself on him, and I sat there aching, hands locked, cock straining my pants.

"Look at it," she moaned, eyes on me, filthy and bright. "Look at your stepsister's pussy taking him. He's so thick, Silas. He's splitting me. You see that? You see how I stretch for your best friend?"

"I see it," I said. My voice didn't sound like mine.

"Tell him," she ordered, riding harder. "Tell him how good his cock looks in me."

"It looks — fuck — it looks perfect. You're dripping on him. You're taking every inch."

Benedict groaned and gripped her hips. His fingers dug in. He planted his feet and started pounding upward, meeting her drops with hard thrusts that jolted her whole body. Her tits bounced. Her mouth fell open. The wet slap of him driving into her got louder, meaner, and she took it, greedy, grinding down to meet every stroke.

"Yes," she cried. "Fuck me. Harder. Silas, watch him use me. Watch him pound this pussy. Benedict, don't stop. Give my stepbrother a show. Make me sloppy. Make me scream."

"You hear her?" Benedict gritted, hips snapping up, cock disappearing into her again and again. "She wants you ruined. Look at this cunt. Look how she grips me."

I looked. I watched her pussy clutch and release around his shaft, cream slicking him, her ass rippling every time he slammed up into her. She reached down and spread herself with two fingers so I couldn't miss a thing, the stretch, the shine, the way she fluttered when he hit deep.

"Right there," she sobbed. "Right there, fuck, both of you — Silas, don't look away, I'm going to — Benedict, pull out. I want it on my tits. I want him to see you cover me."

He snarled, gripped her hips harder, and fucked up into her three more brutal strokes. Then he yanked her off his cock. She spun, dropped to her knees between his legs, and shoved her tits together. He stroked twice and came in thick ropes across her tits. She held still so I could see all of it.

Then she looked at me. Only me.

"This part is for you," she said.

She slid two fingers into her soaked pussy and fucked herself with them, other hand rubbing her clit, Benedict's cum shining on her tits, her eyes locked on her stepbrother. She didn't look at him. She looked at me while she chased it, moaning my name, moaning his, filthy and open.

"Watch me come," she gasped. "Watch your stepsister come with his cum on my tits and my fingers in the pussy he just fucked. Silas. Silas."

She broke. The orgasm hit her screaming, thighs shaking, pussy clenching around her fingers, wetness spilling down her hand. She didn't quiet it. She gave me every sound, every jerk of her hips, eyes open, mine, until she sagged and laughed like a woman who had just gotten exactly the forbidden thing she wanted.

Benedict tucked himself away, grabbed his keys, and didn't linger. "Same rules if there's a next time," he said, and then he was gone. The door clicked. I stayed in the chair, shaking, cock so hard it hurt.

Adriana walked over, naked from the waist down, his cum shining across her tits. She dragged two fingers through the mess, stepped between my knees, and wiped a thick streak of my best friend's cum across my lips.

"Open," she said.

I opened. She smeared it over my tongue. Salt and her and him. I groaned, and my cock jumped against my pants like it meant to tear through them.

She bent until her mouth was at my ear. "Next time I want you to clean me up with your tongue. I want my stepbrother on his knees, licking his best friend's cum out of this sloppy pussy, swallowing every drop while I grind on his face. Say you want it."

"I want it."

She kissed me deeply, tongue pushing Benedict's taste farther into my mouth, her bare cunt brushing the bulge she still wouldn't touch.

When she pulled back I was painfully hard and already addicted, shaking with it, and I knew the next time my best friend finished in her I was going to eat his cum out of my stepsister's cunt until she came on my tongue.
