You begin with a series of wins and seem invincible, but after catching up to your score your girlfriend passes you and beats you at the last few seconds of the final match!
"Damn it, I can't believe I've lost to a "little boy"!" you lays back as you disappointed and throw away your controller at the other couch.
"Aww,... Don't be like that. But don't you ever forget the deal." he replies.
"Yeah, I guess you're right." you answered back to him. "Guess I have to follow it, as loser in 1 round I'll get to take a part of my clothes off."
With that, you didn't have a choice but to follow it, so after your girlfriend in the 10 year old boy form beat you, you take off your t-shirt and throw it on the floor. Then, s/he suddenly saw your nice naked top that s/he can't resist it, but your girlfriend have to endure it and start another rounds. "So, are you ready for another round?" your shapeshifting girlfriend asks.
"Ready whenever you are, this time I'll beat you." you say with the smiles.
"Teehee... We'll see about that." s/he replies as you both continue the game. Later on, 2nd winner of the match is...
