When an older perverted guy who knows better, runs into a girl between 9 and 12 in a bathing suit wearing a white t-shirt over it, and the guy has the disturbing urge to want to see the girls under developed, yet already growing breasts. The trick involves tricking the girl into taking her bathing suit top off with her shirt on, claiming she can not do it. Then when she does it, the guy squirts her t-shirt with water. Most of the time, the girl is gullible enough to think he is just playing around. Sometimes, the girl catches on and isn't very happy about it. In rare cases, the police are called and the guy has a lot of explaining to do.
I was on the beach with my 11 y/o nieces friend. She was wearing a white t-shirt over her bathing suit. I knew it was wrong but I had a water gun and I attempted the Tween Wet White T-shirt Trick. She caught on with what I was doing after the fact and she didn't appreciate it. Neither did her parents or my niece........ or the cop........ or the judge.

When a man, even though he had a vasectomy, has to pull out in order not to leave his wife dripping for the next 12 hours and she doesn’t want it on her gut. The husband must take an old white undershirt and “tuck it” under her ass, creating a canvas for his man juice.
Fucking Trudie man. I got a vasectomy and she still won’t let me bust up in her puss. I have to use the t shirt tuck so I don’t get it on or in her.
