Erika, a college student studying hard to become a certified public accountant. Though focused on her studies, she's also highly sensitive to physical stimulation. One day, pretending to check her heartbeat, I slipped my hand into her bra—and she trembled so intensely she nearly fell off the sofa. During a slightly longer gonzo session than usual, her heavy breathing excited me even more. Lifting her up afterward, I slowly thrust into her from behind in doggystyle, overwhelmed by her responsive, sensitive reactions.
