I think alot of women would like the idea, Perhaps something they may not admit to during the ****** reunion dinner party. But yes, assuming everyone is clean, etc. Why wouldnt they? However pillow talk is one thing, setting up an actual blowbang party in reality is another. I think its probably a normal fantasy for women, pleasing lots of men at the same time, gaining so much attention, the centre of attraction, the physical displays of desire by recieving spurting cum out of numerous hard throbing cocks.
Once a guy can get past the jealousy thing, It must be exciting and exhilarating to see your girl in blowbang, this sex act doesnt seem to be excessively agressive or physicaly demanding on her body.
Especially erotic if she is rubbing and sucking the cocks together, with cum flying everywhere!.
