Sucking Sizhui's cock is really fun. Now that he is more comfortable with the trains movements he can get a good rhythm out of everything and doesn't have to worry about falling again or hurting Sizhui or maybe even himself. Of course he's not really thinking of himself other then this feels good and he loves the way Sizhui gets with each touch. Each lick seems to gain another moan and the more he licks up and down that cock the better Sizhui tastes too. He's a little easily addicted to it, it's just as good as a lollipop even if it tastes nothing like it.

He stops the licking to start sucking on him again. At first it's just the tip, letting his tongue play with the opening and licking up even the smallest of dribbles of precum. Itto has to close his eyes when he takes him further into his mouth, down to the base so that his upper lip is touching Sizui's stomach. It feels good to have something fill up his mouth and keeps him mostly quite, except for the wet sounds of his mouth. His eyes flutter a bit as he keeps a steady pace, taking him all the way each time and back to the tip. He could stay here forever on his knees just sucking on Sizhui.
