how to make sandwiches

Boy: So, sex at my place?
Girl: Yeah!
Boy: OK, but I sleep in a
bunk bed with my
younger brother and he
thinks we're making
sandwiches so this is the
code.
Cheese= Faster.
Tomato= Harder.

Girl: OK?

~Later~

Girl: CHEESE CHEESE
TOMATO CHEESE!

Brother: Stop making
sandwiches! You're getting
mayo all over my bed!
