Imagine your OTP enjoying a night of stargazing. Things are going well, and romantic, they start to kiss/make out and a storm hits. But instead of seeking shelter from the rain they make love under the night sky not caring if they’re drenched. They’re just caught up in the moment of passion itself, the heated air of summer only provides a good reason to enjoy it. Optional: person C of the OT3 helps and equally is caught up in the passion with them.
