Inability to breathe in enough oxygen to fuel an orgasm during cuming. Can lead to asphyxia if the man pulls his cock out of the pussy and his lover, forgetting herself, takes half the cock in her mouth and passes out from lack of air and too much cum.
My wife started gasping for air as she came and almost passed out when I flooded her throat with cum. I backed my cock out of her, flipped her light body over on her stomach, grasped her around the chest just below her D cup boobs and pulled up. She hawked out a large luge of cum, swallowed ater spitting it out, and caught her breath.
