My first time

The best humor!Let us enjoythe following joke.Have fun: 

It was in the dark sky,Just her and I.I knew what she wanted;I tried my best.So then I placed my hand on her breast.It was then I knew what she wanted to do.She spread her legs,I felt no shame.Because then the white stuff,Slowly came.So it's done now;My first time,Milking a cow!
