Perfidious Cum Challenge

It will be hard for you, maybe even impossible. But you'll do anything to make me squirt, won't you? After all, your urges want to get out of your already too plump sack. So of course you will take up my challenge. I will fuck you extremely hard and drive you to the edge of despair, that's for sure. Can you manage the balancing act? You only get to play this game once, so you only have this ONE chance!
