I've done a few kinky things in my time... I had two guys at once in a public toilet, an ex-girlfriend picked up a stranger who fucked her in a car park and came inside her, which I promptly licked out when she returned, but I guess my top one so far is watch my fiancée fuck ten guys whilst I was hidden away in a nearby wardrobe. I peeped through a small hole, and they had no idea I was there. Reality really CAN be better than porn!
Another thing my fiancée and I enjoy is that she will meet strangers and suck their cock in a public loo, and when they have cum in her mouth she keeps it in there and then we share his cum in a very public kiss. Onlookers think we're having a romantic kiss- how little they know what is actually taking place!
I've yet to do the kinkiest things on my "to-do" list. My fiancée wants to practise polyandry- she wants to have several husbands all living together- all well hung studs so that I am constantly cuckolded every hour of every day!
