We had a gangbang with my bf (me, my bf and some other guy - lets call him X). It was fantastic but after that I cant stop myself from doing these stuff.

I had sex with X alone, without telling my bf (so i guess i cheated on him). That was the first time i did such thing.

Now I am seeing X sometimes a week and we have sex, and he wants to have an other gangbang with an other 2 friends of his. I am so excited about this but I know I have to stop seeing him and not have the gangang.

I know i became a total **** and i really enjoy it. But i really love my BF and I dont wanna hurt his feelings. On the other hand, i really wanna have a gangbang with 3 strangers.

What shall i do? Do it once? Tell my BF? Or stop fooling around and go back to my normal life?
