Your mom invited me to "talk" so that I can stop bullying you...the "talk" is going really nice in her room. Don't worry about the noises coming out of her room....
After your crush found out you liked her, she said you could kiss her on one condition, if your bully gave her a facial you had to clean up with your tongue.
My wife was trying to get my bullies to stop bullying me but they ended up being too much for her. So she asked my mom to help and now they're both my bullies bitches.
Its not that you hated your BFF or wanted them to suffer - but your best friend's sister was so cute and well so was his GF - could you really pass up the chance with both of them? Maybe your best friend will never even know you used their sister and GF
