Oh oh oh oh oh oh oh
Oh oh oh oh oh oh
Oh oh oh
I'm so into you,
That I forget about the world
You got me blind,
Blind, so baby,
Let me be your focus,
Only got one thought,
In my mind
It's you, you, you
Baby you just got to be mine
Only thing I gotta do is make it right
Oh baby, oh baby
Baby you just got to be mine
Oh no what I gonna do without your love tonight
Oh baby, oh baby
Chorus:
So baby, so baby
Oh I'm telling you I want it that way
So baby, so baby
Oh I need your body next to me all the time
You know what I mean?
When you touch me, I get hot, hot, hot
I'm feeling like a freak, freak, freak
So baby, let me put my body on your body, yeah
Oh baby, oh baby
Bridge:
Now don't be shy, take off your disguise
Come on and make a move, make a move for me, yeah
(Come on) yeah baby now's the time (Time) to show your love for me
And let me hear you say Oh Baby Oh Baby (Say it again) Oh Baby Oh Baby (Come on)
Chorus: ……（重複）…… 結束。
