Sweet Brains

1. Penis being sucked beyond recognition.

2. Being able to put the penis and balls in an entire mouth.

3. Oral Sex so good, you didn't even want the pussy afterwards then made a sandwich and went straight to sleep.

4. Sucked your soul through pee-pee hole.

5. Head Candy.

6. Curled your toes then and your toe nails fell off.
7. Oral sex so good, you flashed back and jerked of to the memory of it later on that day.

That girl with the eye patch gave me ridiculous head last night. Some of the best i've ever had, Sweet Brains...
