Hey, so me and my gf where horny and she gave me a blowjob (didn't do it till the point of ejaculating or climax). Later on, we wanted to feel our genitals touch, so I just put my penis on her vagina. There was no intercourse or penetration, there wasn't the "just the tip", I didn't "came", I just passed my dick up and down outside her genital (roughly about 3s). Also, she was on her ovulating cycle and she's supposed to be on her period about tomorrow or the next day after tomorrow. How likely is the chance of her getting pregnant?
