I don't know why but for some reason I was compelled to return the favor this young man had granted me. I was a little nervous about someone walking in on us but that only made it that much more exciting.  With his every thrust in my mouth I could taste the thick pre-cum. I would massage his taint to release even more of this delicious nectar into my mouth. It was intoxicating. In fear of getting caught, I made him jack his dick while I made out with him resulting in a lovely explosion of boy juice.
