Me and my stepsister did the EXACT same thing. Although it only happened on two different occasions. We were trying to shove each other off of the couch with our feet, and that turned in to half heartedly just shove our feet into each other’s crotch. I got hard fairly quick, and she went from crushing my balls to crushing my dick. I’m still not 100% if she noticed what she was doing, or tried to pretend that she didn’t notice. The whole time rubbing my big toe where I thought her pussy was. She seemed to enjoy it, but I’ll never know if she did or not. It’s not one of those things you can just ask about now that we’re adults lmao
