Once you get to the swingers club, it automatically leads to one of FIVE possible endings:
1. You leave Tracy alone and don't tell the guys t treat her with respect: She has a bad experience.
2. You leave Tracy alone, but you DID tell the guys to treat her with respect: she leaves with the famous actor and his friends to have an orgy at his mansion, and eventually leaves Justin.
3. You stay with Tracy, but before the gang bang even starts you cu in the doctor's mouth. AND, you've been cheating with Lisa, and you didn't know, but Tracy has found out. She wants you to eat her after the gang bang, and if you say yes, you get the cuckold ending...
4. if you say no you get the divorce ending.
5. You stay with Tracy for the gang bang. You tell the guys to treat her with respect. You can fuck the doctor but you don't cum until the end of the gang bang: You get the happy swingers ending.
There may be a bug for the fifth. We had to fix it once already, and maybe there is still something wrong. Basically, the only way you should get the cuckold ending is if you have been cheating with Lisa AND you cum before the start of the gang bang at the swingers club, AND you stay and watch the gang bang with a wet, limp dick. It seems like people are getting the cuckold ending a little too often, and I guess we'll have to look into that.
But dudes, it's a very complicated game to code...
