You feel the warmth in your testicles begin to swell and spread through your cock as well; it felt like it was throbbing before; but now it was really throbbing; and each throb was intense and pleasurable sending shocks through your body and making you shake with your moans. You are so lost in the hot pink haze of your pleasure that you don't notice that with each throb your cock swells to greater and greater size; it was already about 13 inches hard; now it was bordering 16 inches; and over a foot of cock and now swelling to a foot and a half of cock was at least nine to even ten inches thick now as well. You know in the back of your mind that a cock like this could easily destroy an ass if you didn't prepare it properly; you are so lost in the lust craze now though that you don't care. You almost hope that you destroy the boy's ass; some part of you feeling an animal hunger and need to dominate his asshole; the other part of you that was more sane and in the back of your mind wanting to punish him for whatever he was doing to manipulate your mind and body. (Although a third voice in your head is enjoying every hot sticky perverted moment.) Still rubbing your swollen and leaking head against his puckering hole. You can barely contain yourself; the only thing slowing you down from fucking the shit out of him is the fact that just doing this rubbing your head against his hole and pumping out copious amounts of pre-cum is actually intensely satisfying; but you know you won't be able to stop yourself from penetrating him very very soon.
As you continue to throb and swell against the young man's boy pussy. The Storyteller prepares the next magical bondage art; twirling another finger and mumbling another incantation; the magical bead of sexual energy zooms off the tip of the young man's finger; spins around through the air; and shoots straight up and into your hole.
