Say 'aaah'

You open your mouth, stick out your tongue and close your eyes and go "aahh"

"Oh fuck Lily, here it cums"

You feel the first shot of cum land across your face, the second straight in your mouth, then he sticks his cock in your mouth and the rest of his load fills your mouth. You swallow it all.

after he pulls out of you with a moan, you say "Didn't realize we were those kind of friends."

"Well I for one wouldn't mind"

"of course you wouldn't" you say "Actually, maybe you can help me with something..."
