Making Sandwiches

There was a boy about 18 years old, and he still lived at home.
He and his girlfriend were out for dinner, and when they came
back they wanted to get a little...busy;). When the boy came
inside the house with his girlfriend, his parents were just
leaving. Your little brother is sleeping in his room. They two
older ones started making out and soon they went to the boys
room to get in bed and do the horizontal. That's when the boy
remembered that his brother was still there, sleeping in the
bottom bunk bed they shared. He was sound asleep, so the boy
told his girlfriend that they would have sex in the top bunk,
and use code. They stripped down and he said,
"ok, if you want me to change positions, say lettuce, if you
want it harder, say tomato." Soon the girl was screaming,
"Lettuce"
"Tomato"
"lettuce" over and over. They woke up the little boy. That's
when the little one said,
"can you two stop making sandwiches up there...you're getting
mayonaise all over me!"
