The dream nature is almost definitely to blame for how much he eases into the touch, allowing himself to make noise and squirm and press into Jack's hand without a single care in the world. It's so much easier when you don't have to fight old hangups and can just lie back to enjoy it.
He makes a displeased noise as Jack breaks the kiss but okay, fair point, he can't really complain about the turn of events here. Hell, he'll even lift his hips to help with getting his jeans off and fuck if a hand is warm then a mouth is goddamn scorching. Always did like to play with fire.
"Fuck..."
(( I can never decide if he does or doesn't so expect inconsistencies with this in the future! ))
