My sister has a low sense of chastity, and I see her as a potential slut. That being said, I get aroused every time I see her panties or breasts, so I'm not sure why. Still, we're brother and sister, so we try to keep a certain distance between us... One day, while I was sleeping, I felt an itch in my lower body. What's this?! I looked at my lower body and saw my sister sucking my dick! What's more, she was giving me an irrumatio without my permission, with a look of ecstasy on her face! Yes, my sister was a super sex monster! Of course, it didn't end with just a blowjob...
