We slightly prefer one night stands as she loves variety and I love variety for her. However, there have been two or three guys that have been a long-term.
Yes, love when her guys share her with others. Several have done it before. The other guys just see her as some cheap whore to be fucked and that really excites us.
My wife has been on vacation twice at resorts with two different guys where they have fucked and fucked and fucked!
I really get off on guys using her for their own pleasure and not necessarily hers. His pleasure takes priority.
