Madness

My gf is a few years older and more experienced than I and likes to set up provocative situations especially where she is Domme. We have explored some cuckold fantasies and may act out a scene where she will tie me naked to a chair and force me to watch a friend of hers pump his BBC in her arse after which I will be forced to clean his nasty member and eat out her violated bum.
Making me rock hard just typing it. She also has a chastity cage she may lock me in at the same time. She's so wicked.
