They go into Raph's bedroom

The Hamato family came from old money, so they lived in a very sizeable home, there were seven bedrooms (One master, five for the children and one guest room) all of them had ensuite bathrooms and only the master had a walk in closet. The way they were distributed was, the master bedroom was in the first floor, and on the second floor there was Leo's bedroom, Raph's bedroom and the guest bedroom, on the third floor there was Miwa's bedroom, Mikey's bedroom and Donnie's bedroom. Raphael's bedroom was right next to Leo's bedroom, so Leo could often hear his brother if he was listening to very loud music, and a few times he heard moans coming from the bedroom, but they were always porn videos Raph watched when he forgot his headphones weren't plugged in. As he stood in front of the door, Leo kept his hands hiding his cock, while Raphael grinned and leaned against the wall.

"Well... Open it"

Leo took a deep breath, he knew his twin, so he knew the bedroom would be a mess of hidden cigarette butts, socks and underwear, t-shirts, jackets, and more. With one hand hiding his junk, Leo took the handle with the other hand, and opened the door.
