A sheet shark is a girl who sneaks under the bed sheets while your sleeping and performs surprise oral sex on you

Waking up with a morning throbber while your partner is asleep still, you try to sneak your hard one into her ass while the sheets are still in front of you.
You want sex but you know she will not want you to wake her so you go for the fast kill and try to slide it in, but you get caught by the sheets(Sheet shark)!
