Hi there.
I'm currently writing a 'choose your own adventure' style text game. The story evolves, but I have troubles with a particular scene.
It's about a guy in a whirlpool with two girls who are girlfriends. They know each other already but so far the player only had had sex with one of the girls.
Now they met together at a SPA resort, and the player and his girlfriend need to perform some teasing action to "convince" the other girl to join them for a 3-some.
The other girl is not a shy one but is more reserved type and is not very interested in the player.
So my question is: what should the player and his girlfriend do during the whirlpool scene to attract the other girl and get her joining them for sex?
I'd like to go for some kind of the corruption path, but it should be a bit realistic. Any suggestions?
