You let her blow you.

You decide you would like to experience what her mouth feels like. You take your dick out of her pussy and tell her to get on her knees. And she does. She understands what you want and doesn't waste any time. Before you know she is sucking your hard cock. You hear her moaning on your dick. She must have done this before. You push her head further on your cock and she takes it like a champ. Do you change it up?
