Genma thrown his senbon at the front door so he could get to the blond when he was done opening the door. He didn't give Naruto even a chance to get the keys out of the lock before he turned him and attached his mouth to the blond. Not that Naruto wanted any other way, he is after all Kyuubi's jinchūriki and over the years he had a few of the fox's tendencies and a rough sex was one of them. They tumbled their way to Naruto's room, helping each other out of their clothes on the way there.
They barely got to the bed. He attack the blonde's neck and from there went down, not before leaving his mark. Moving down he made sure he left a mark on the blonde's heart. All the while the blond was withering underneath the brunette. It's been a while he had some and Genma aggressiveness wasn't helping. Genma played with Naruto's chest changing between licking it, biting it and blowing on it. After a while Genma decided to go further down and dip his tong in Naruto's navel and the working his way out on the sealing that held Kyuubi. Naruto being extra sensitive there almost came, barely holding it back.
After Genma was done with the sealing he kept going down, he decided not to torment his blond anymore so he started sucking his blonde's mushroom head while his hand was moving up and down on his base and the other he give to Naruto so he can suck on them and cover them with his saliva. When he knew that Naruto was close to come he pulled his fingers from Naruto's mouth and started playing with his blond back entrance and before he came inserted the first finger receiving a half moan half groan from both pleasure and pain. He deep throat Naruto while insert a second finger. Naruto grab the bedding beneath him so hard his knuckles were white. And loud moan was heard and Genma knew he found his prostate. Remembering where it was and kept preparing him. When he insert his third finger making sure to hit the prostate and humming while having Naruto deep in his throat proved to be too much for our kitsune, he came screaming Genma's name which only got Genma harder. After he swallowed all of Naruto's come and cleaned the little bit that had escaped, he pulled his finger out and positions himself at his entrance and entered in him and kept going until he was fully inside of his lover.
He moaned at his loves tightness.
"Fuck, Naru Baby, you're tight."
"Genma, move."
Nothing more had to be said. He started slow or at least that was his intention until Naruto crossed his legs around him, he lost all his patience and starting going faster and harder until they both came screaming each other's name, in the high of climax Naruto moved by instincts bit Genma's neck while Genma did the same they bit till it was bleeding. Naruto licked Genma's neck and the wounds healed fast for both of them but the mark stayed. Naruto's also healed but his mark also stayed. Genma pulled out of his blond lover and pulled Naruto to him. He fell asleep with Naruto in his arms and already asleep with his head on Genma's shoulder. Both had a happy and satisfied smile on their faces.
