My sister lightly touches my crotch. The direct touch between my legs made me ejaculate in a second! And I shot so much that it stained my pants.... My sister noticed this and teased me, calling me a "punk-ass dick," and she played with my dick even more, so I ejaculated again... But when my sister saw me ejaculating repeatedly, she got excited and the situation changed completely! My sister, who used to be so cocky, has become a bit more rounded and wants me for real! My hyper-sensitive premature ejaculation complex has become a weapon!
