I groan as I stroke my dick once while I stare at the bottom half of her face. She hasn’t shown her face in any of her pictures, but this one teases with a mouth reveal. She isn’t smiling like a normal person would for a picture. No. She’s captured her O face—or what she wants everyone to think is her O face. Her lipstick is smudged, like she just got done sucking a cock, and her lips are parted as though she took the picture mid-moan.

After taking screenshots to save in a private album, I read the caption.

He wanted to show me his thanks for letting him eat his dessert. ;) What a mess he made of the both of us.

Want more? Link in bio ;)

My molars grind together at the mental image of Madison with her fiancé. Where he’sshowing his thanksfor letting him eat her pussy, as she so graciously described in her post. Jealousy courses through my veins as I imagine the piece of shit fucking her face right before the picture. I don’t believe he did, since her lips aren’t swollen. Maybe he’s small and couldn’t bring that reaction out of her like I would. But for the sake of my sanity, I tell myself none of what she implied happened.

Curious about what she means by the link in her bio, I check out her profile and tap the link. Options pop up to go to her TikTok, Instagram, and OnlyFans.

Jesus Christ.

She’s not just posting on social media. She’s creating content for a website many people use to upload sex videos and nudes for money. There’s no way her fiancé knows about this. Madison isn’t using her real name on her social media or OnlyFans, so it’s safe to assume she doesn’t want him to know. It could be because he would react horribly to this new information. Toxic men often feel threatened and inadequate when a woman does sex work.

I click on the OnlyFans link, and it directs me to a funnel page where I can subscribe to see her content. I don’t hesitate as I sign up under a fake name. Once the payment goes through, the paywall drops and I have unlimited access to all of her videos and pictures.

My fingers tighten around my thickened cock, and I bare my teeth from pain and pleasure.

Now that the bout of anger and jealousy has faded, only uninhibited desire remains. Madison willingly posts this type of content, knowing full well people masturbate to it. It would be stupid of me to deny myself the enjoyment.

I choose a random video. Madison kneels in front of the mirror, with soft music playing in the background. She slowly strips out of the maid outfit while touching herself. I hiss through my teeth as I stroke my cock, not giving a shit that I didn’t spit in my palm or grab some lotion to use as lube. She opens her legs and slips her hands between her thighs to tease her pussy.

“Oh, god,” Madison whimpers in the video. “I’m so wet.”

My fist flies faster on my dick, the burning sensation adding to the pleasure. I can’t look away from my phone as my little sister puts on a show. She arches her back, pushing her breasts higher while she fingers herself.

I’d kill to be in the video with her, just so I can shove her onto her back and spread those thick thighs, giving the patron a good view of her pussy before I devour her until she soaks my face with cum.

I edge myself to her video, matching her pace. Right before I come, I stop stroking myself and wait for the orgasm to fade.

“Fuck yes, baby,” I growl as Madison sinks a finger inside her wet pussy.

My breaths come out choppy, matching Madison’s frantic gasps as she pushes herself closer to the edge. Right as shethrows her head back and whines in pleasure, my bedroom door flies open. Light from the hallway spills into the dark room, exposing what I’ve been doing in private.

“Fuck!” I exit out of the app, cutting off Madison’s loud moan right as it hits its crescendo. I release my white-knuckle grip on my dick and push myself up with my elbows on the mattress. “What the?—”

“Ryder!” Madison dashes into my bedroom and throws herself onto my bed, right on top of me.

Pain mixes with pleasure and jolts through me until I see stars. My lips pinch together, and I hold back a pained groan. It hurts, but like the sick freak I am, I get even more turned on.

“What the fuck are you doing in here?” I grab Madison by the arms as she shifts to get off me. I mean to throw her off the bed. Instead, she ends up straddling me, with only the thin sheet between my erection and her pussy.

I clench my jaw and settle my palms on her love handles. A normal brother would shove her off and tell her to get out until he’s decent, but I never fit in that box. I hold her in place and shift my hips, swallowing a moan as my cock grinds against her center. There’s no way she doesn’t feel my erection as she sits here with a terrified?—

Terrified? Why is she afraid?

I sit up and slip my hand over her lower back. “What’s wrong?”

“Justin. My fiancé. He said he’ll see me soon,” she blurts out. Tears shine in her eyes as she looks at me like I’m the hero who will protect her from the rest of the world.

I frown. “Why the fuck did you talk to him?”

“No.” Madison shakes her head and grabs my shoulders, her nails biting into my skin as she gently shakes me. “I didn’t. He’s been calling nonstop and leaving voicemails. We have to go.”

I cock my head and rip my gaze from her face to look for her cell phone. She’s attached to it, so there’s no way she would leave it downstairs. The light spilling into the bedroom from the hallway gives enough illumination for me to spot the pink case on the edge of the mattress. I snatch it and hold the screen toward her.

“Unlock it. Are you sharing your location with him?”
