Rika, my childhood friend and a former basketball player, has always dressed and acted so boyishly that I treated her like one of the guys. After I jokingly suggest that an adult woman should wear sexier underwear, she takes me seriously and appears in lingerie. Her full tits and thick, mature curves have been hidden beneath those boyish clothes all along, and seeing her suddenly shy destroys my self-control. As if making up for never viewing her as a woman before, we both get wildly turned on and fuck again and again.
