Lastly, you may not have sex outside the experiment until your role is complete. Is that clear?” he asked.“Yes, my boyfriend might not like it, bu...t anything for the sake of science!” she said back to Dr. Fabor.“Now - I’d like to start in three days.

On my arrival I couldnt believe that my sons friend Andrew was now a good looking strapping lad. He must be six foot too with good looks too.

She slapped her hard dick on my face and sneered allowing me to catch my breath before pushing her dick back into my mouth. I opened up and accepted it once more despite the total lack of arousal or enjoyment on my part. After a further ten minutes of this treatment.
