I made a once-in-a-lifetime request to my college-student sister. Desperate not to embarrass myself in front of her for the first time, I pleaded with her until she finally agreed. Surrounded by her marshmallow-soft, voluptuous breasts, I was overwhelmed by intense pleasure, nearly climaxing again and again. I lost my virginity to her with a condom, and the shock of that moment was indescribable. Awakened as a man, I secretly removed the condom, causing my previously unresponsive sister to suddenly become fully aroused. In that instant, a new relationship was born between us.
