Διαγωνισμός cum κερατά.. Ο φίλος μου πρέπει να παρακολουθεί!

My ex won't leave me alone.. He pitches a bet -- He wins, he gets to fuck me anytime he wants.. I win, he leaves us alone forever, and pays for our upcoming vacation... The catch? My boyfriend has to be tied up and watch while it happens.
