Prompt: He doesn't hate to bottom, per se. He just finds it uncomfortable and embarrassing and strange, so he'd stick to oral, manual, intercrural, or topping if he could, except he also considers himself a decent fellow, and since Aramis loves to top too, and Aramis is willing to bottom himself, it just wouldn't be fair.

So, for special occasions, Porthos lets Aramis top. Aramis acknowledges that Porthos is doing this as an extra special favor, so he does his best (and generally succeeds) at making this as enjoyable as possible for Porthos.
