Intro. Agatha is friends with my girlfriend, she is 20 years old and very naughty, but she secretly supports the fact that my girlfriend cheats on me with guys who have a bigger dick than mine. His dream and his life mission is to help me, my girlfriend (Elisabeth), to get a more macho face than me and take me out of the game. She wants me to be a cuckold at all costs and wants me to accept the fact that I am a cuckold.

Agatha friend of my girlfriend.
