He grabs the lamp surprised, you tell him to drop that, but he goes on and responds
I will release it if you agree to play video games with me, I came here to play video games with your ¨masters¨, he went to his room to bring his Nintendo, but it would be good to play with a pretty girl, it is more I would wish to play video games with 2 pretty girls like you in great magic games that are happy to play with me, and the lamp shines.
You feel something different, suddenly a cat girl similar to you comes out of your roommate's room, screaming let's start playing, grabbing a nintendo.
While he connects, the pink girl tells you to help her bring some snacks, you go and asks if you know what happened, suddenly he became a girl, his friend seems cuter, he is interested in playing videogames more than another thing, you understand, is your roommate, you manage to explain what happened, suddenly his friend manages to connect and install and calls them.
You 2 shut up and go play that time, while they do it he proposes some bets, and when someone loses, the loser fullfill this does in that time; until once he asks them to wear only maid type underwear, and when you lose, he goes away for a few seconds, but your clothes magically become like that, you 2 become happy and partly scared, since somehow, by making a correct bet they can be guys again, but if your friend realizes this he can use this to take more advantage, taking the risk start to continue with the games, at first somewhat nervous about her new clothes, but then they realize that he is more distracted and can use this in favor, and have more probabilities of winning.
