Pushed back with no space left in the lift, Catherine is forced back, and her ass lands firmly but gently on my groin area. Immediately my cock goes to full mast, and I, stuck, have no way to go back. She quickly turns back with a look of surprise, and recognising me behind her, a look of anger flashes on her face, as she realises there is no space to move away from my cock. I break into a panic, but with Catherine's hot ass rubbing his cock, no man can bring down an erection.
Then, suddenly, I feel her ass slowly turn in a circle, grinding against my groin. I have never felt such pleasure, and at first think that perhaps Catherine likes me. It is then that I notice her mischievous smile in the front mirror and realise her aim: to humiliate me and force me to cum in the lift in the presence of other people in the lift. Panicking, I try to distract myself and bring down my erection, but no man can do so when the buttocks of Catherine are rubbing his groin. I feel my orgasm coming closer, and start sweating. I grit my teeth, trying to hold my cum back, but a woman's power over men cannot be defeated, and soon, I let out a load groan in the lift as I shoot my cum into my pants: once, twice, thrice, and even more cum keeps shooting out, and I see Catherine's grin widen as she feels the throbbing of my cock as it ejaculates, satisfied that she has punished and humiliated me, and proved women's dominance over men. The other people in the lift state at me due to my moan, but I, red faced like I have never been before, look down, and become even redder as I see the big, wet patch of cum on my trousers, and feel it run down my legs. A slight stench of semen permeates the room, and as Catherine exits on the eighth floor, she whispers to a female friend, who takes one glance at my trousers as I hurry to cover up with my suitcase before laughing and leaving the lift.
Humiliated, and recognising the power of women over men, I resign after realising that the story had spread to all the women in the workplace. But a small part of me still wishes I could fuck the shit out of that hot bitch.
