For a while, you both start the match as you both press the button so fast, then after that, you just beat your girlfriend in 10-year-old boy form so easily.
"Hah ha... I've won!" you yell and jump out of the sofa as you win Victorious.
"Aw man, I can't believe I've just lost! I should have morphed into somebody who is so expert in gaming skill." your shapeshifting girlfriend lays back on the sofa as s/he disappointed and throw away the controller at the other couch.
"Aww,... Don't be like that, babe, you still got 2 chances to win the match." you replies back to him/her as you cheer her up for a bit. "But don't forget the rules, whoever loses the 3 matches, will be strips a pieces of their clothes." you replies.

"Ready whenever you are, this time I'll beat you." A shota/your girlfriend says as s/he focuses and ready for the next match.
"Wow, even when s/he's in the form of little boy, still cute as usual." you thought as you look at her/him. Then, you both press the start both to continue the match. Later on, 2nd winner of the match is...
