Mayonaise

There once was a guy named Jo who was a senior in high school.
One night Jo and his girlfriend Pam went out, they went back to
Jo's place. Jo shared a room with his younger brother. Jo and
his younger brother Tom Had a bunkbed. Tom was already sleeping
on the bottom bunk so Pam and Jo went up to the top bunk, So Jo
and Pam started fooling around and Pam started screaming. Jo
told her if she wanted to go harder to say Tomato and if she
wanted to stop to say lettuce, so Jo checked if Tom was still
sleeping thankfully he was. So they started:
"Tomato"
"Lettuce"
"Tomato"
"Lettuce"
"Tomato"
"Lettuce"
Jo screamed "ahhhhhhhhh"
Then all of a sudden Jo's little brother said: "stop making
sandwiches your getting mayonaise all of over me!"
