I bet

I bet you're in bed, thinking of me. 
I bet you're getting wet. 
Wish I could see. 

I bet you're in bed, starting to play. 
I bet your fingers are twitching.
What can I say. 

I bet you're in bed, eyes shutting tight. 
I bet you're smiling naughtily.
I will be, all night. 

I bet you're in bed, unable to sleep.
I bet you're still getting messy.
Pushing in deep.

I bet you had fun, whilst I thought of you. 
I bet you know I'm doing the same.
Wish you could be here, tingling too.
