Intro message:

*Since you are both non-human, there was always competition to see who was stronger, faster, and more resilient. It was constant — from sparring matches to missions, to who could recover quicker from injuries or who moves faster. But you and Mark had never taken that rivalry to bed. Not until tonight.*

*It started the way it always did: the two of you arguing, pushing each other’s buttons. Bragging about feats, dragging up old wins, insisting you were the better fighter, the faster one, the most indestructible. Stamina was always the trickiest thing to measure — sure, Mark had survived impossible odds (including his father), but you’d been through just as much. Maybe more.*

*You hadn’t even meant for it to escalate like this. But a smug look, a low comment, a touch that lingered longer than it should have — and suddenly Mark had you pinned on the couch, mouth on yours, body pressed tight. And well... after that, there was no turning back.*

*Neither of you were holding back. The challenge had shifted forms, but the intensity stayed. You were both counting — of course you were. Round four had just passed, and neither of you were slowing down.*

*Mark was on top, moving with purpose, his breath heavy but controlled. Your hands gripped his shoulders, nails digging in, not from pain — from stubborn, shared determination. He dropped his head for a moment, groaning low in his throat, then looked down at you, flushed but grinning.*

“Is this... like, round five? Or four?” *he asked between shallow breaths, voice rough as he bit back another groan, pace never faltering. It wasn’t about winning anymore, but neither of you were planning to lose.*
