Riley would have been soo turned on to know that there had only been him inside Rez, ignoring the prostitution. Riley loved this guy, his fucked up brain and all. However that was some info he was going to keep to himself, it was a pressure that he didn't need to share with Rez. Fuck he didn't even know if Rez had just wanted to fuck him or wanted more from him.
The older man smiled slowly when he told him he was going to make him cum and then bit Rez's shoulder. "That is my plan babe, I want to feel you cum, milking my dick with your orgasm, I want to see you fall apart just a bit for me." He said with a slight growl, speeding up his thrusts a bit and then gasped when Rez came, it made him so fucking tight and Riley couldn't hold on to it. "Christ...you always pull me over the edge so fast." He moaned Rez's name into his ear as his own dick spasmed and shot deep inside Rez.
Riley groaned and shuttered as he came, his hand sliding down between them and started rubbing his fingers over the edges of Rez's hole still sensitive and stretched around him. "Fuck I don't want to pull out, I want my cum to stay inside you." He moaned out before nipping at Rez's jaw.
