Rumlow knew it was fruitless, but every single time, he still fought. There was no overcoming his alpha, not without a tranquilizer gun, a pair of magnetic handcuffs and that muzzle the Soldier was force to wear on missions. With his hands caught, he tried to twist them free but was unable, and the point became moot when his wrists were bend enough that it forced his back to bow and a snarl of pained rage to leave him. Pain gave him clarity, gave him a brief opportunity to circumvent the needs of his heat and this... well, it wouldn't be the first time he returned to HYDRA with a broken bone because of mating.

The kiss split his lip almost instantly, the metallic taste of blood making him shudder as he fought back, struggling even as his wrists were passed off and his head was bent back. He suddenly swung up a knee aiming for the groin but his balance was off enough that he'd land on the Soldier's thigh instead. A tongue in his mouth was a dangerous thing; he could bite it off. The problem was that with the Soldier's tongue there, the taste of alpha swung him out of his pained rage and into omega in heat territory and while he fought, it was against his nature to permanent harm his alpha was in heat and after just being mated.

It was all biological nonsense, but he was subjected to it all the time. He mewled softly, hoping to distract the Soldier enough to break free instead.
