Blindfolding welcome

I have this big fantasy that I repeat in my mind all the time.

The fantasy begins with my birthday or just some day that I'm coming back from work. At home my beautiful girlfriend is telling me that she's very horny and blindfolds me right away. I lay down on bed and she starts to give me this amazing blowjob. I can't hold it any more and I have orgasm, giving her a facial cumshot.

Then my girlfriend takes my blindfold off and I realise that I came to some of her friend (female) and my girlfriend only seduced to wear a blindfold.
