After my father remarried, I suddenly got a gal sister who started mocking me for being a virgin from our first meeting. Then she nonchalantly flashed her panties in front of me! Even if I'm a virgin, I have rights and sexual desires too...! I gathered my courage and immediately had sex with my sister! With all my might, I pistoned her to the point of multiple orgasms! This is the power of a virgin! But my gal sister, who still looked down on me, made me cum inside her multiple times!
