She also kissed and licked my back and shoulders which also kept me hard. I had also found out that, while I was just sixteen, I did have only a finit... amount of semen. There was no way I could match my super-horny stepmother and began limiting the amount of arousal she would give me by hand and even mouth so I could fuck her as much as we both wanted.
