[Verse 1: Stefan & Dru]
You're close to cryin'
'Cause you just broke up with your girlfriend
(That stupid ho)
You've got a token of love, but with nowhere to spend
(Nowhere to go)
You're on the sofa, watchin' your favourite cartoon
(Tryna cheer up)
You hear your sister, and she's playing on her bassoon
(She knows what's up)
[Pre-Chorus: Stefan]
If you're lonely, and no one will do
Then I got some advice for you
[Chorus: Stefan & Ash]
Kiss your sister
Just give it a crack, woah
I don't think it's incest if she's kissing you back
Kiss your sister
Just try it for size, no, no, no
I don't think it's weird
Unless your sister's a guy, that's your brother
[Verse 2: Ash, Stefan & Dru]
It's two years later
And you're standin' there with your bride
(That stupid ho)
You can't deny it
But someone has just caught your eye
(You're thinking, "Woah")
You see your sister, and she is mouthing "No"
(It's already too late)
Something takes over
And you realise where you should go
(This must be fate)
[Pre-Chorus: Ash]
Speak now, or forever hold thy peace
And go and get yourself a piece
[Chorus: Stefan & Ash]
Of your sister
Just give it a shot, woah
I don't think it's strange if your sister is hot
Kiss your sister
Just try it for size, no, no, no
I don't think it's weird, unless your sister's a guy
And I don't think that's weird
Because I think gay is wrong
But then, you're kissing your brother
And that's a whole other song
[Bridge: Stefan]
You travelled North and South
And East and West
Only to find that kissin' your sister is the best
You travelled East and West
And North and South
Only to find your tongue's most comfy in your sister's mouth
[Chorus: Stefan & Ash]
Kiss your sister
It's good for your health, woah
And if you close your eyes, it's like you're kissing yourself
Kiss your sister
She's always been there, yeah, yeah, yeah
In every family photo, you've been sniffing her hair
Kiss your sister
