Heat of the moment(Septiplier A/B/O Smut)
Mark's eyes widened, all his muscles tensing. This was bad. Really really bad.
"Jack." He said shakily, not looking at the omega.
"You have ten seconds to lock yourself in your room. Don't come out, no matter what I say." He said. Jack panted, looking up at him.
The commanding tone in Mark's voice had Jack bolting, running into his bedroom and locking the door. It was getting too hot. His clothes were suffocating. He quickly pulled them off.
Mark was breathing erotically, pupils dilating with lust. No alpha can resist an omega's first heat.
