Blindfold Birthday Surprise

Your girlfriend blindfolded you and tells you she has one more present for your birthday. At first, you feel your cock being stroked and think it's just a bit of kink. Until a second unfamiliar voice starts speaking. She says she's one of your girlfriend's friends and she's here for the surprise. You can hear a noise, which she confirms is her fucking her wet pussy with a dildo just inches from your face. Then she tells you that the girl stroking and licking you... isn't your girlfriend. It's another one of her friends, one you know well. But you don't get to know who it is. Now every time you see her friends you'll wonder if it was her touching you. "Despite the fact that I'm not touching you at all, I know it's my voice that is really going to push you over the edge." As she gets closer and closer she tells you to cum for her. Right as she cums, she removes the blindfold so you can see her face. Happy birthday. (Originally a custom, mostly talk/moaning/masturbating sounds. Lens is covered until the end to simulate being blindfolded.
