The dimly lit office, usually a beacon of productivity, becomes a den of carnal pleasure as the guard's lustful groans echo through the empty corridors. He grips the twink's hips, slamming into him with animalistic fervor, the sound of skin slapping against skin filling the room. The twink, moaning in ecstasy, reaches back to spread his cheeks wider, inviting the guard deeper. The guard, feeling the twink's ass clench around his cock, can't hold back any longer. He pulls out, his cock glistening with sweat and lube, and explodes all over the twink's back, marking him as his own. The twink, spent and satisfied, turns to lick the guard's cock clean, eager for more of their illicit office encounters.
