At least it wasn't your boyfriend fooling around with your brother.

You would respond by breaking up with him and never trusting your sister again with the men in your life.

How does one come up with that cover up?!.........it's flawless!

I...shocked. I'm also jealous. Never cheated, don't intend to...but Im intrigued by the thought of fooling around with hot girlfriend's hot sister. Guess I'll live vicariously through FMLs like this.

Try waking her up by a punch to the face. And a nice kick to the balls for your ex-boyfriend.

When people obviously lie to my face, the only thing I have to say is "**** YOU".

You respond by dragging him out of your house an then beatin the shit out of your sister. If she is that bad of a person to help someone cheat (especially on her sister) then I'm sorry, I'd be an only child.

Stare into their eyes whilst taking a shit thus ruining their moment.

^^ Wannabe.

I'd respond by helping wake the sister up by beating her backstabbing ass!! Then move on the the scum bag cheating ex-boyfriend and give him a parting kick to the nuts and punch to the face!!

How the **** do you walk in on someone in the shower? Can you not hear the shower going?

Well maybe the door was unlock and she was still half asleep...

Sorry that happened to you. Hopefully you will find a new boyfriend

never talk to her and for the boyfriend right then and the sick him or kick him in the balls grab his clothes throw them outside drag my sister out the bathroom and lock her in the room then draag the boy outside lock him out go turn off the water tell my father and let him do the whipping to my sister

#173 I ment sock

That would backfire, because it would mean that OP probably has an STD too.

Telling a lie to your sister that the boyfriend has a STD doesn't mean OP has one.

I think #15 was assuming that they have had sex before so he gave her the std

The point of saying the OP's boyfriend had an STD, was to try and scare the OP's sister.

Yeah, you can't break up with your sister but you can take a poop on her bed.

YDI for having a shower. Naw jk, but you're ex boyfriend is a scumbag.

40 - I misread your post as "take a poop on her head". Honestly, I think my idea is better.

Nah, mine is bed-er.

Amen to her sister being a bitch and the boyfriend being a douche. I wouldn't dream of doing this to my owns sister, or best friend.

"Well, she was having a sex dream and I was only half awake and I thought it was you. But don't worry, you look better naked." -Bf to OP

You would think they could come up with some better excuses. Sheesh, some of these just make me want to facepalm and walk away

Excuses are like ass holes. Everyone has em, and they all stink.

I highly doubt that.

No it does, i've smelled it before

Was this the same girl who tried to sneak out and punched her dad?

i thought she punched her mom?^

That's funny right there

Wait so did he wake her up?

Have surprise butt sex!

Nah, don't dump him, what did he do wrong? Sarcasm. Of course she should dump him, Sherlock.

I like how this comment is right under the previous one ending in "is to..." I dunno, I thought it was cute.

Maybe they were trying to save money on the water bill by showering together ..

71 - So that's why OP's boyfriend didn't want to shower with her! I knew he was hiding something.

Agreed you would have to be the most stupidest person to remain with a non-faithful ass wipe.

Doesn't everyone?

If you sleep in the nude, there's a mighty good chance that sleepwalking would also occur while in the nude. Think about it . . . There you go!

When I sleep walk in the nude, I have lots of fun. This morning, I woke up with a G-String full of $20 bills.

Perfect!
