Alex's efforts to prevent herself from cumming would backfire. While she had managed to delay it, she had effectively just edged herself and now as she fell helplessly over the edge, the orgasm was bigger than it otherwise would have been. Her hips began to thrust on their own as the pleasure took over, and her pussy went wild as she squirted. A huge torrent of cum splattered messily out of her cunt, spraying over the gears thoroughly. But up above, a huge amount of milk shot out of her too. Her whole body was shaking as an unreal amount of fluids poured out of her. When she finally came down, cum was dripping from her crotch and white trails of milk ran down over her stomach and legs, her nipples still leaking at a constant rate. She had probably produced over a gallon of cum and milk, all things told, but her supply was infinite. She pouted, face bright red, feeling so embarrassed that her body had been altered in this way. She could cum gallon after gallon and never run out or experience the effects of dehydration. Alex could imagine that succubus laughing somewhere in this castle, watching her body betray her. The thought made Alex so embarrassed and humiliated, but there was nothing the girl could do while the machine continued to restrain and rape her.
