Bi Now, Cleanup

I clean my older girlfriends (36 yrs) pussy after she fucks other guys. If I don't do it she won't let me have sex with her anymore. I hate the taste of sperm and it ruins her wonderful tasting pussy when it's mixed with it. I hate it and she laughs about it, then I get to fuck her and clean her up again. Last summer she let two guys fuck her on a nude beach, everyone watched and they all knew I came with her. Then she made me lick her clean in front of everyone. A lot of laughing and chuckling at me. I was caged at the nude beach, it was humiliating. I love her, I love her perfect body even though she's much older than me, and she taught me how to fuck in all holes, and makes me take it also.
