The common definition of a gangbang is anything over 3 or more men fucking a passive woman in succession, one after another. This varies from group sex where the woman is more active and may involve spit roasting, double penetration, etc. The thing is when a woman agrees to participate in a gangbang, there is an implied agreement that she will take on all comers, regardless of who they are and what they want to do to her. Once she is in a room full of black men and she is stripped naked along with them, she has lost control and is vulnerable to their every whim.
From our experience, these situations may start as a gangbang but can morph into something else. The first time I watched her do an all-black, some of the time was one after another but at time it was double or ever triple penetration on her.
There are so many things that can make it unexpectedly difficult:
First: The sheer physical exhaustion. Sex can be strenuous and when it's one woman takes on several men, it's a LOT of physical activity.
Second: Condoms, yes, or no? When my wife chose not to use them in the 8-man gangbang, I witnessed, and I can tell you it's a mess. By the time the third or fourth guy had filled her with their semen, every bare black cock that pushed inside her pussy ****** copious amounts of jizm out of her and all over the bed. I lost track of how many loads were dumped into her or she swallowed.
Third: Her consent to doing those 8 men implied that she could not refuse any of them, no matter if she finds them repulsive. That can be awkward, if she tells one of them no.
Fourth: The slut factor. How will a woman feel about herself after? How will you feel about your wife or girlfriend after? Can you live with it?
From what my wife told me afterwards, 8 men was a bit too much and wouldn't willingly agree to that many again. Perhaps, 3 to 5 is about right. To the original question, Electrifying? Yes, at times but at times it was overwhelming for both of us, and I was surprised at the sights, sounds and especially the smell of sex, sweat and mixture of her perfume and their cologne. I also came to the realization that I could not stop them from doing whatever they wanted to do. Keeping control of the situation is almost impossible.
