POV: I run into my sister's boyfriend, we talk and he tells me that she is very angry with him for something stupid, so I offer my help to make him feel better, I MAKE HIM CUM IN MY PANTIES. First I bring my body closer to him, I unbutton my shorts, I pull down my panties and begin to rub his erect penis between my vagina and my legs, thus stimulating my clitoris and making me wet, we play until he cum, leaving my panties full of milk and that's how I put them on.
