There's nothing to complain about when Harry's walking around their flat with his cock swinging about, nothing to complain about when Harry's pressing himself up against Louis' naked backside when he's reaching for a mug in their cupboards, and nothing to complain about when Harry's got his hand firm on Louis' arse when they're cuddling on the couch. So, in reality, it's really fucking weird, and Louis knows that. But that doesn't mean he doesn't like it.
