Idea for a cuckolding game:
How to play: Find the kind of guy who isn’t ugly or something, but who is such a shy and nerdy virgin that he would never get a girl on his own. These kind of guys can for example be found at the computer science department of your local university.
Then take this guy home and make him a present: Your girlfriend will give him a handjob. And even better, if your girlfriend doesn’t get him to cum within two minutes, she will also give him a blowjob. If he manages to not cum for another two minutes he can fuck her doggy style and cum inside her pussy.
