    Let me tell you a story about tissues. Man, last night I was feeling so
    emotionally drained, I mean I was just out of it. I got home, cooked up a
    microwaveable meal set back on the couch and watched reruns of full house.
    Then a scene came on with Becky. I set my macaroni to the side and slowly
    unzipped my pants. and I started to stroke it slowly but surely. It didn’t
    take long before I felt a rush flow through my body that felt like the drop
    from Tower of Terror. I came so hard and so fast that I nearly lost
    consciousness. My man milk shot through the air like a rocket splatted
    right into my macaroni. And also dribbled all over my legs. Thinking that
    there were tissues on the end table I reached over trying not to let my man
    juice drip on the floor, but there were no tissues there, so I had to
    scream for my mom and have her bring me some tissues from upstairs and wipe
    me off.
