It isn't even that he shot down into the toilet as much as we cannot see him doing so per se THOUGH I love probably more than anything is seeing the shooter's face (of which we do see a bit of) as he reaches orgasm and cannot hold it any longer having to let go shooting sperm and semen over and over again. I wish I could be right there with him in between his legs holding onto one of his shoulders with one hand and one of his legs with the other to tell him to just let it come out of his penis. Then once he starts shooting telling him, "Ahhh, yeah! That's it! Take your time! Just let it come all on out of your penis!" as he explodes! And then rubbing my hand all over his back in a passionate manner showing my love and admiration for him for doing such a good job and telling him, "That's it. Ah, you did a GOOD job. I love you!".
