They have to not be having any sexual relations yet at that point
and the more platonic they are at this point, the better.
Could be marriage of convenience, fake dating, or they’re boss/employee on a business trip with only one bed available.
Whatever the reason (yall know how the one bed trope works already), but this should be the first boundary crossed in their relationship.

Bonus if she squirms, and he puts a hand on her hip to hold her still.

Bonus, if he blushes after or feels embarrassed and the rest of the day is awkward.
