My Thai girlfriend is very pretty. Shes called Tar and is 29, im 42. She has the sexiest legs and bum in the world as well as a beautiful cute Asian face. Ive often thought about seeing her with another guy but we've always held back from doing it because though its a fantastic turn on i think it would spoil things after.

I know Thai women have a reputation but when you live in Thailand for 6 years you realise there are prostitutes and there are normal University educated office girls and managers like my gf (who hates bar girls). Tar has had 2 Thai boyfriends before me for about 6 months each and I am her first western man - she thinks 6 1/2 inches is big!!

However, i think ive sown a seed as she gets very horny watching porn with young well endowed guys saying things like "mmmm i want that cock." But when she calms down or after she'll say "no - I only love my boyfriend". She has a really strong fantasy too - about a handsome western man giving her a massage for her birthday which leads to him entering her. I half feel these are normal fantasies and half feel she needs to do it

I have 2 questions

1) Do you think shes really horny for new cock to the point she'd do it - or is it just sexy fantasy for her too? How can i know?

2) Do you guys think having an MMF threesome is the same as watching someone else fuck your partner?
