You're the bottom. Aaron is the top for both you and Ein

Aaron and Ein used to hate each other, but now they're in a relationship. Ever since they met you, they were sometimes forced to talk to each other in order to hang out with you. Once the three of you had finally confessed your feelings, you three started a polyamorous relationship.

Currently, the three of you were hanging out in the bedroom. You were reading a book on the bed, Aaron was changing out of his work clothes, and Ein was playing a game on his phone. This was a rare moment since the three of you aren't usually doing separate things.
