.. I knocked their door and she answer it... I already had some interactions with her in the market but damn.... she is so fucking sexy, my cock was s... hard that my pants start to look too tight... I was so ready to fuck her right but when I told her that I was there because of the letter she told me that was a mistake... She said that her husband wrote the wrong number, she was so embarrassed, then she told me that it was supposed to be for the couple that live next door (their number is 52. ’ ‘Thanks, but by six o’clock Wednesday, I’m sure I’m going to be ready for a break. But I will need to get home afterward and finish my write-up to turn in on Thursday.’ ‘Whatever works for you,’ she said brightly. Then we disconnected. By the time I got to Jamie’s laboratory on Wednesday night, I was pretty wrung out. I still needed a couple hours of word processor time to finish the redraft of my thesis, but during my drive to her lab, I was able to give some thought to her prosthetic. Almost subconsciously I shook my head, “I’m gonna regret this...” my hesitation extended and I felt Sue’s big toe drop away from my sac as she leant forward. “Go on” she dared me, the smile faltering on her mouth but curiosity sparking behind those eyes. I leant forward also, mimicking her as I did, “I... I got the feeling that... you might have been wishing someone else was there instead of me...” She arched one of her eyebrows, “Really?” “Oh... I’m so not complaining... but...” “But?”. More times than she wanted to count each day she closed her door, as if someone may catch her, and fingered herself until she was wet and frenzied. Pulling out one of her toys she would touch her clit and be in heaven. She rubbed on her clit, hitting the spot that made her jump, and then she'd insert it into her wet, wanting pussy.Back and forth she would continue, changing the settings to tease herself until she was panting. Masturbating on all fours was her favorite way; it reminded her of.
