Not all the time
I was once playng water polo and tried to scoop the ball from this girl from behind just as she passed it, and ended up firmly grabbing her breast
She was convinced from then on that I was like her stalker.
Still, if I could choose to have not accidentally grab her breast, I wouldn't change a thing. She had huge tits, and she's been a bitch to me the previous day so I wasnt really even sorry.
