The bulge in his own thin pajama pants had already grown considerably. And that actually made me pretty horny again too. So I continued where I had le...t off. I enclosed my cock and balls with two hands and jerked off. Secretly rubbing my butt hole with one finger. I spat in my hand and rubbed it lustfully over my hard cockhead."Fuck, Yeah! ... You do that so well ... Here, take a look at that cock of mine, while you wank yourself off, brother.", he said panting horny. He pulled his nearly stiff. Because you’re finally realizing that I could do it, aren’t you? And it hurts, doesn’t it?

Because that’s about one percent of how much I despise you right now.”“And Kathryn?” he asked, suddenly concerned for her. She watched his hands as if mesmerized; her mouth, having gone dry earlier from the fear of discovery, now flooded with moisture as desire flowed through her. She watched his fingers trailing up his stomach and fondling his nipples, pulling at them, rolling the small buds, and she felt her own nipples tighten and harden in response. "Well, well."

"We need to get the washcloth," he said hoarsely."Forget the washcloth. I want to feel your cum on me," she encouraged with vigorous strokes.It was too much for him. He had just been told to cum on his sister and obediently complied. He quickly painted a sloppy line of cum down her chest to her belly button. Feeling her brother's cum must have been too much for Juliana as well as her hips then began bucking and twitching while she cooed in pleasure. She squeezed the last few drops from her.
