These two sisters are good friends and share everything, including boyfriends, sex friends, dicks, and sperm! If the younger sister is having sex, they call the older sister, and if the older sister is having sex, they call the younger sister and have a friendly threesome! If either of them finds my erect dick, they'll share it together, make them cum equally many times, and at the end they'll share the sperm that I cum in their mouths together! Of course, we have to make them cum equally during sex, so I'm exhausted... But I'm super lucky to be able to have such an erotic threesome!
