[It's that last part that makes Hiccup shoot up to stand and tug on hips and kiss him deeply, putting every bit of need and greed that he's felt in the last few hours into that kiss, tongue pushing into Jack's mouth without asking. He doesn't really care about the bead of pre slipping down his cheek or the way his cock throbs in his jeans.

He pours every feeling he's ever been capable of into the kiss, tongue swiping over Jack's and letting him taste himself as he propels him back towards the bed, falling on top of him when his knees hit the edge but keeping himself up by putting his hands out onto the mattress to catch himself.

Hiccup pulls his head back just slightly, hair messy from having fingers run through it, lips parted a little. His breathing shallows, hand spreading out over Jack's torso as he presses a kiss to his neck.]

I'm going to fuck you. [His voice is low, husky as his hands take hold of slim thighs.] I'm going to take you so that next time your body will remember my dick. I'm going to buy you a toy the same length and have you sit on it in class while your classmates have no fucking clue.
