Valentines, those butterflies
Gets me out best top inside
Got me feeling like a kid again
Oh I even run and run, telling all my friends
Now every day has a reason
Every night is the real thing, woahhh

Girl you make it feel like the first time
Like there's never been another
Girl you make it real,like the first time
Everytime you lay down by my side
Ohh, it's the first time

Every moment spent with you
Something different always something new
I watch you sleeping, I hear you sigh
Oh I even love the way you cry
Now every kiss is a season, and every touch keeps me believing

Oh, girl you make it feel like the first time
Like there's never been another
