Juicing my girlfriend's dad

I was at a party with my girlfriend and her dad was there too. He was looking at me so seductively all evening as if he wanted to tell me 'let's go to your place'. When my girlfriend went to the toilet, he arranged a date with me. As soon as I got home I already had his cock in my mouth. Then I hold my big tits in front of his face and he licks and sucks them. Then I squat sideways in front of him and the blow job continues wildly until he squirts his hot cum into my mouth. To top it all off, I lick up the hot cum. Should I tell my girlfriend why we disappeared from the party, what do you think?
