cheating on girlfriend (FemboyPov) (NTR warning)

Amy sits on the edge of her bed in the dim glow of her laptop screen, the room feeling emptier than it has in weeks. Posters of bands you and Amy both loved curl at the edges on the walls, and the stuffed bear you won her at that fair last summer stares back with glassy eyes, like it's judging her impatience. It's been twenty-three days since you left for college—twenty-three days of radio silence after you's promise to FaceTime every night. Her thumb hovers over the call button, heart thudding like a trapped bird against her ribs. What if you's just busy? What if you's... forgotten? She hits call before doubt can swallow her whole. The ringing echoes through her earbuds, each unanswered tone stretching longer than the last. Finally, the screen flickers—you's face appears, but it's all wrong. you's hair, once cropped short and messy, falls in soft, dyed-pink waves around you's cheeks. Mascara smudges you's eyes, making them wide and doe-like, and you's lips, painted a glossy cherry red, part in a gasp that's half surprise, half something else. you's shirtless, or at least the lacy trim of a crop top clings to you's shoulders, and before she can process the collar around you's neck—black leather with a silver ring glinting like a promise—you jerks the phone away. But not fast enough. For a split second, the camera swings wild, capturing the chaos behind you. A dimly lit room, not a dorm—more like a basement den, walls scarred with graffiti and strung with fairy lights that cast everything in a hazy, illicit purple. And there, looming over you from behind, a guy—tall, muscled, tattooed arms flexing like coiled ropes. No face in frame, just the raw thrust of hips slamming forward, burying deep into... you. Amy's boyfriend arches on all fours, a high, keening whimper spilling out, "Ahh—f-fuck, yes, harder, sir!" The dom's hand cracks down on you's ass, leaving a red bloom, and there's no condom, no barrier, just slick, glistening skin-on-skin as the thick length plunges in, pulling out halfway with a wet schlick before driving back. you's hole clenches visibly, greedy and stretched, a dribble of pre-cum leaking from the caged thing between you's thighs—pink and frilly, like it's been locked away for worship. The screen freezes on that glimpse, then blacks out as you ends the call. Amy's breath catches, a mix of horror and something hotter twisting in her gut, like watching a storm cloud burst open. The phone slips from her hand, clattering to the floor, but the image burns behind her eyelids—you's transformed body, soft curves where there used to be angles, yielding so eagerly to that brutal rhythm. What the hell happened to you? Who did this? And why does the thought of calling back make her pulse race like she's the one being claimed?
