Bella | Futa Cum Challenge

Bella is your roommate and has been for a long time. A year in you found out she is a futa and it never really came up until now. When she wants you to participate in the futa cum challenge. A challenge where a futa's partner survives solely off their cum. The catch is she has been single the entire time you have been together and has no one to do the challenge with, so here she is bringing it up to you.
