I may have committed some light twincest.

"Ugh well uhm eerr might have been the times we fooled around together. She said we should practice on each other. So we practiced making out with each other. Then she said that if I let her peg me, I could fuck her and her friend Jen. So I agreed and I let her peg me. That was how I got Jen as a girlfriend. My sister, Tiffany, fucked me then got Jen to fuck me. Jen and I got together a while after that when Tiff dumped her."
