TO FAR

I really enjoy being a cuckold. I've watched my then gf and now my wife enjoying the pleasure of other men's cocks. It's not about the size of their cocks or the colour but about them taking my wife without my permission and about watching her sexual satisfaction. I know this sounds strange to most but being powerless as I watch her bull decide her pleasure, not me really turns me on. A strange twist has developed though! My wife's latest bull takes her upstairs and I'm not allowed to watch but instead I'm relegated to listening at the door. I get so aroused imagining what he's doing to her and by the moans and screams he's obviously doing something right. That's not the twist however, he's started exhurting his dominance over me by (I'm so ashamed to say it) by waking me up as I sleep in the spare bedroom face fucking me as my lovely wife films is act of dominance over me. At first I hated it although I didn't resist his advances. It's happened three more times since but the last time I only pretended to be asleep, laying there waiting to for my mouth pussy to be willingly used. I've got used to the taste and even look forward to his fresh pre-cum before he get's back to servicing my wife. The cuckolding I can take but are they conditioning m me to be bi and what will this lead to?
