How my best friend would fuck my girlfriend in front of me (mix)

Well my best friend know I would like to be a cuckold, and he would be ok to fuck my girlfriend in front of me or to fuck her both, on threesome. For now, she's not ok because she's very shy (attention : nobody here will have a pic of her, so don't ask :p), but when she'll be ok, OMG she will just become a whore and I will be so exciting to be a cuckold, and watch her take lot of cum on her bitch's face :p
