What can you do when your roommate is on your bed with a stiff cock?

My roommate is the weirdest and most fun. he loves to wear black and is a rebellious and crazy twenty-something. many times we argue about the parties that are mounted in the apartment. but he always ends up driving me crazy and it doesn't cost me anything to forgive him. like today when i come home and find him on my bed with a stiff cock and fucking his ass with a rubber toy. what a delicious thing when i put him on his knees and he starts licking my stiff and wet cock about to burst.
