Two-bit: Depends on how drunk he is. If he's very drunk it'll be a fullout makeout session. If he's tipsy it'll be a passionate deep kiss. If he's sober it'll be a couple short sweet kisses.
Johnny: I feel like it'd be like maybe a nervous short sweet kiss
Ponyboy: A short sweet kiss, only when Darry isn't home though
Dallas: Full on makeout session. I mean come on its Dallas f-ing Winston.
Darry: Sweet kisses!!!! Not very often though, he's a very busy man.
Sodapop: I don't really know. Maybe a mix of passionate deep kisses and sweet ones.
Steve: I don't really know about this one either. Dudes wild to me so imma say like Deep French kisses
Tim: He doesn't kiss you often, but when he does I belive they would be sweet.
