The girls had come in to keep me company, and I’d spent a very strange couple of days with Mrs. Polaski as she had me take one test after another. O...r original schedule called for us to be tested over a week and a half, with the tests spread out to one each day. I’m not sure if it was some sick game of hers, or she just wanted to see how far she could push my abilities.She didn’t actually know about my abilities, but she’d spent enough time with me to realize the girls, and I weren’t average. Most of the showers had doors, but one had just curtains on it.One day Ryan had a late class so I wasn't going to be able to suck him for awhile, and I was horny so I figured I'd go take a shower and work on my ass a little bit.

She turned to her sister. “Misty Compton is teasing us!“ There was another set of twin squeals.They were so honest in their appreciation of her that she couldn’t keep up the false front of being a famous musician, who was above all this.“Calm down!” she laughed. “I’m just a girl, like you. You’re making way too much fuss about this.”“You are not just a girl!” said Betty, her face. We're related and you want to fuck me but eating another man's cum out of my pussy is too fucked up? Fuck you! What are you afraid of, your reputation?"I just stood there staring, not knowing what to say. I just wanted to fuck her. And I was so close! And who would ever know what I did to make it happen...She caught me, saying, "That's right... You're thinking about it!"She pulled me down to my knees and pushed my face into her sticky crotch. I immediately got to work wanting to get through.
