You left an hour ago.  He was watching you, again.

As I lay here, my hand slips into my shorts while thinking of how my hands ran through your hair while you knelt between my thighs.  Your tongue brought me to the edge and you held me there for what felt like forever until you took me over and I screamed from one orgasm to the next.

My fingers are simply not enough without you.  Come back to me soon, I need you so much! 

And to answer your question, yes love, he knows, but cannot accept it — yet!
