Easiest by far to acquire. Just pay his father and he'll whore out his son for free. He waits for you in the couch, his bed. You take off the sheets and expose his mostly naked body, due to the lack of AC. Only wearing his underwear, you savour his mostly chubby frame, grabbing his manboobs and passing your hands through his belly. He'll protest, but being a pubescent teenager he quickly gets hard and dirties his white boxers with precum. You rip his underwear apart, exposing his chubby cock. You suck on it, making him moan, then stop, nuzzling against his footpaws, taking in his scent. Then you lick his taint, then his musky asshole. It's too much for you, and you quickly take out your cock, lining it with his hole. You thrust into him at full speed, making him grab the sides of the couch as he winces. You turn him around, on his elbows and knees, making him your bitch. Just as you're about to cum, you slide out, grab him by the scruff and open his mouth, making him suck on your cock, his own musk and your cum driving him over the edge and making him cum himself. He becomes your permanent side piece.
