My girlfriend, who is also my casual sex partner, is extremely timid and easily panics when scared. When we're together in abandoned places or dark areas where no one else is around, she screams, "Eek! I'm scared! Squeeee! I love you so much!" as if she's actually enjoying the thrill, clinging to me tightly out of affection. During one such outing, shortly after entering an old building, she said, "I need to pee." Calmly and coolly, like a handsome, collected guy, I replied, "Sure, just go ahead and pee here." At that moment, not only did she start urinating, but her pussy juices also began oozing out slowly. I discovered an unexpected side of her—she gets turned on by thrills and engages in perverted acts like using a potty, revealing her hidden fetish.
