(I’m having a sleepover with my boyfriend’s sister. We’re talking before we turn in for the night.)

Me: “I’m looking forward to the morning!”

Sister: “Why?”

Me: “Because I can tell your brother that you got me in bed before he did!”

Sister: “Indeed we shall!”

(The next morning.)

Sister: “So, [Brother].” *slings an arm around me* “I feel like you should know that she’s great in bed!”

Me: *laughing hysterically*

Boyfriend: *glares at sister and hugs me* “I’ll be taking my girlfriend back now…”
