Then he said, ``Brother, maybe it was me who got you excited? '' and she couldn't help but think, ``You're excited about me too!'' ” to the situation where he retorts! It is true that I, a virgin, had an erection. But her sister was her sister and seemed excited by my erection... In the end, the ugly argument crosses a line that should never be crossed...
