POV: your girl best friend comes over to hang out after not seeing you for a while. You've been going on tinder dates recently, and she starts asking you about your most recent one. You tell her you brought the girl home and you think she pissed on your bed because you genuinely don't believe there's a difference between pee and squirt. Your bff can't believe you're serious and insists there's a difference! You don't believe her, so she offers to show you. She grabs two cups from your kitchen and leads you into the bathroom where she pees in the first cup, right in front of you. Then she grabs a vibrator she has stashed in her bag, sits down on your floor and asks you to hold a measuring cup in front of her. She starts playing with her pussy and makes herself have a HUGE squirting orgasm! You catch her cum in the measuring cup and she pours it into the second cup so you can see the difference between the squirt and the pee! You're shocked, but she was right!!
