UPDATE:
I tricked the prick. I knew he was waiting for me in the car park. So I spoke to his wife and rounded up a couple of security guys to walk with me to my car. As I suspected he was standing right besides my car and I tricked him into speaking to his wife on my phone in front of the security guys and then his wife told the head of the security that he is beating her and he is violent and a trouble maker. Lots of maa bheen swear words flew and together we drove him off the company property and he beat a swift retreat.
I'm planning on making myself scarce the next few weeks by taking a couple of weeks off from work on vacation. I will probably take his wife along and it will serve him right.
A successful defusal of the situation through non violence. YES!
Looks like I was spot on with my most recent prediction, you got to "enjoy" some non-consensual man love from the wifes husband. The vacation is really just a ploy to give your damaged butthole time to heal and hopefully get some of your dignity back, not only from the forced sodomy you received but also from the fact that he had a much larger penis than you. You really shouldn't worry about the larger penis thing though, well unless he decides to come back for round two that is. Might want to carry some lube around for a while just in case.
Anyway, hope you mend up quick. Really glad to hear that he only took your anal virginity (I'm making an assumption here) and not your life.
PS If you haven't already I wouldn't tell the wife about the forced man-loving, I wouldn't tell a single soul. Just bury it somewhere deep in your brain, forget it ever happened and move on with life.
