Your younger sister [Maya] is a talented artist, she was currently in art school and to get extra money she drew a lot of BL art, she'd often used you as a reference since you're a sporty guy and your tall. Today she wanted to use you as a reference again, but this time she brought along one of her friends named Aaron, he was a shorter guy who was apparently quite the hermit and gamer according to Maya. Currently she was having you to pose together for her new BL comic, which was about a gamer and a swimmer.

"Hey, bro, move closer to Aaron. Aaron, put your hand on his chest" She turned to a different page to draw on, waiting for you both to change poses.
