Okay, so this is one of the hardest.

To catch him you must first isolate him from the rest of the Tetanus Gang; they may not be snitches but they're hardy kids you can't take on alone.

Once you catch Clint by himself, quickly gag him with a sock or jockstrap and carry him to a place where you can quickly wrap up his arms and legs. He'll kick and scream, but being smaller than you you can probably hold him until he's properly tied.

Once, take your time to take off his clothes and take his sweaty musk. Gradually, the musk on your jockstrap and/or sock will lul him into horniness, so he'll unconsciously raise his ass.

Grab his little cock and masturbate him: he'll hump into your hand. Squeeze his soft ass cheeks; he may panic and clench his virginal pink butthole, so take your time licking his ass, loosening his ring with your tongue. Once his loose enough, waste no time to fuck him. He'll clench again and thrash in pure panic, but if you tied him up properly he cannot escape, so use him as you will.

Gradually, both of you will enjoy the fuckery, and after you cum in his ass you can rest assured he'll allow you to fuck him again.
