That just riles Rak up more.

Not only did Mut stop him from going out when he looks this good, but the asshole is now baiting him into coming, fully clothed and untouched. Rak refuses to go down without a fight. 

He grabs Mut’s face and licks into his mouth, coaxing the other’s tongue with his own.

“But I want to come on your cock.” He moans softly, eyes open as he deliberately bites Mut’s bottom lip and sucks on it harshly to help tempt Mut further. 

Mut pulls back completely and stares, his eyes darken as he watches with rapt attention as Rak licks their spit off his swollen lips. 

“You know I can make you come more than once,” Mut chuckles, “Not like I haven’t done it before.” He reminds Rak with a quick kiss to his pouty lips. “Want you to come like this first. You know I like it when you make a mess.”

He kisses him again to silence the bratty comeback, “Now be good and fuck my thigh.” Emphasising his last sentence with another deep grind, and it rubs so perfectly against the head of Rak’s cock that he almost comes right there. 

“Fuck. You.” Rak groans as he does as he’s told and undulates up and down on Mut’s thick thigh. 

At some point during the chaos, Mut hoists him up from the bed until Rak is literally straddling one leg. 

Together they move as one, rotating hips, slick mouths, hot breath, sweet sounds and Rak forgets everything he thought he knew about sex, because right now he feels like he’s floating, his only anchor the thick, muscular body beneath him, as he ruthlessly fucks himself on Mut’s thigh.

It’s almost embarrassing really, how easy it is to get him there. 

Mut always knows how to use his body to make Rak feel every little bit of friction that lights him up from the top of his head to the tips of his toes. So when he does feel like he’s about to topple over the edge it surprises a deep whine right from the back of his throat. He rips his mouth from Mut’s and throws his head back, cursing out the name of the man who made him come in his pants like a horny fucking teenager. 

On the come down Rak feels entirely wrung-out and bared wide open, but his body refuses to cooperate so he flops onto Mut like a dead weight and lets himself be manhandled by the smug bastard until he’s lying back down on the bed. 

“I win.” Mut says sweetly, with a not-so-subtle hint of cockiness. 

“Huh?” Rak replies, eyes still firmly shut. 

“The bet, khun. You seemed to enjoy yourself very much.”
