I want you to love me, like I'm a hot guy

Keep thinkin' of me, doin' what you like

So boy forget about the world cuz it's gon' be me and you tonight

I wanna make your bed for ya, then imma make you swallow your pride

 

Want you to make me feel like I'm the only girl in the world

Like I'm the only one that you'll ever love

Like I'm the only one who knows your heart

Only girl in the world

Like I'm the only one that's in command

Cuz I'm the only one who understands how to make you feel like a man

Want you to make me feel like I'm the only girl in the world

Like I'm the only one that you'll ever love

Like I'm the only one who knows your heart

Only one

 

Want you to take me like a thief in the night

Hold me like a pillow, make me feel right

Baby I'll tell you all my secrets that I'm keepin', you can come inside

And when you enter, you ain't leavin', be my prisoner for the night

 

Want you to make me feel like I'm the only girl in the world

Like I'm the only one that you'll ever love

Like I'm the only one who knows your heart

Only girl in the world

Like I'm the only one that's in command

Cuz I'm the only one who understands,

like I'm the only one who knows your heart, only one...

 

Take me for a ride

Oh baby, take me high

Let me make you first

Oh make it last all night

Take me for a ride

Oh baby, take me high

Let me make you first

Make it last all night

 

Want you to make me feel like I'm the only girl in the world

Like I'm the only one that you'll ever love

Like I'm the only one who knows your heart

Only girl in the world...

Like I'm the only one that's in command

Cuz I'm the only one who understands how to make you feel like a man

Only girl in the world

Girl in the world

Only girl in the world

Girl in the world
