Isabel + Tiffany - Shared boyfriend

Not a real life situation this time - we just wanted to do something different in this hot weather! Tiffany and Isabel are chatting about a recent party. Isabel is proudly showing her a facebook photo of her new boyfriend and that drives Tiffany mad because that is HER man! Tiffany can't believe they are sharing the same boyfriend and starts chasing her. Finally she catches her and while she is kneeling above her Isabel simply pees. That makes Tiffany even angrier and as a punishment she wets her shorts and pees on Isabel. This is a very humiliating moment for Isabel and she spends some time cleaning her clothes in the lake after Tiffany leaves...
