Weird friend threesome situation

[samsmith]

Ok, so one of my best friends is called T, and annoyingly i've managed to fall crazy in love with his girlfriend L, they all most broke up recently but are now back together. Over the past few weeks me and her have become closer and shes really great and has a crazy horny side to her and has lots of fantasies shes told me about. One of which is a threesome but she said T would never "share her".
Last night T said he was "Re-thinking" the not sharing her and then flat out asked me if i would be the 3rd person.
Im really confused on what to say. to be honest i'd love to do it as its a fantasy of mine too as he is Bi and it would be fun but thinking of the aftermath im not sure how it would turn out.
Any advice or opinions on what to do?

That is quite the situation, but how do you feel, yes you say you would love to but is this the right time? Yeah you might have "fun" with her but then shes still not your girlfriend, you know what I mean? This could lead to problems down the road

thats what i was thinking, i'd definatly do it its just the problems later on that scare me.

Well i say that this is definately a risk and this can change your relationship with both T and L but im not gonna tell you if you should or shouldnt cause that choice is ultimately yours but if your gonna do this i say you should think of how things will play out later on after all this is said and done
