Naruto's Seal [Gay]

Naruto is a ninja warrior from the Hidden Leaf Village, but that's a story for another time. Naruto is a positive guy, always smiling and ready to be there for the people he loves. He can also be a dumbass and a little stubborn but has his heart in the right place. Lately he's been having conflicted feelings about himself, although he dates one of the prettiest girls in the whole village, called Hinata, he also feels a primal attraction to his teacher (or sensei) Iruka. He doesn't think of himself as gay and won't admit it but since his teacher came out of the closet Naruto can't help but want to explore that side of his sexuality. His naturally high libido doesn't help at all, he masturbates everyday and sometimes more than once. As for his looks. Naruto is blonde with very short spiked hair often wearing a bandana around his forehead, his eyes are big and blue like two shinning jewels, his skin is tanned with a bit of a rosy blush despite his asian heritage and he has marks on his cheeks that resemble whiskers, like that of a fox. He's about 6 feet tall and quite muscular, far from a swollen and rigid bodybuilder, his muscles are soft enough that you can feel his skin fold but hard enough to show the good shape of his fit, ninja body. He has an above average uncut cock with more length than girth and a normal ballsack, his body hair remains exclusively under his armpits in tuffs, a little patch above his penis and some short folicules around the rim of his anus as all men do, all of it blonde as the hairs on his head. The curtains match the drapes. Speaking of his anus, Naruto has a virgin pucker, very pink and tender. He often sweats all over his erogenous regions, not as different as a normal guy of his age and stature but he tends to get off to his own musk. Though he eats a lot most of it goes to his thigh muscles and ass giving him a more bottom-heavy look, that doesn't change the fact that his body looks almost perfect, size and proportion-wise. Emotionally speaking he has some daddy and mommy issues that he worked through his infant and teenage years, most of it at least, since Iruka was the first sensei in the village to ever care for the boy with food and teach him a valuable lesson he has deep respect and admiration for him, no matter what the people of the village say about Iruka's newfound sexuality. Naruto is also very energetic and has a contagious presence, what might be seen as an obnoxious behaviour to others might just be his way of telling that he likes you. The people of the village all want him to be the next leader, the Hokage, and he wants it just as bad as everyone else, despite the fact that his dad was Hokage at one point, way before him, and it consumed his family and eventually life as well. Naruto is certain that he can make it better. Naruto has a strong spirit but a frail mind. The seal that Iruka put on him can have pretty serious consequences if not handed carefully by a master of ninjutsu. The seal makes it so that the bearer is unable to have an ejaculation but still experiences a share of the orgasm, when the cum is about to leave the subjects penis it goes right back from whence it came. These effects of the magic ninja seal can pile up on eachother because the subject remains unable to get less aroused, wich make orgasms easier to have, that causes more pent up arousal, this can go on and on until the person who cast the seal removes it causing all of those orgasms to come out at once into one single ejaculation. A very potent one, a person under such pent up orgasmic power can experience a total loss of control and become a nymphomaniac, lose control of their bladder and even cause permanent body changes.
