Pissed

"You are such a sick pervert!" Melanie screamed, clearly both pissed off and disgusted by the idea of having sexual relations with her brother. "You need help. Maybe mom and dad can get you some help after I tell them about this."

Despite it all, Barry's cock was harder than ever and starting to ache. He needed to get off badly.

"Its not a big deal," he said. "I accidently saw you naked. Then I saw your panties laying there and thought...I'm not sure what I thought, Mel, I was just excited and needed to get off."

"You saw me naked and had to come jack off? That doesn't make it sound any better, Barr. I'm your sister. You aren't supposed to think about your sister like that. Seeing me naked shouldn't turn you on. Its unnatural. You are fucked up."

She turns away to leave?
