She has an orgasm with a dildo and I ejaculate in her mouth

I insert a dildo of at least 20 centimeters into my girlfriend while she moans with pleasure and sucks my cock very richly and caresses my testicles. She can't take it anymore and she cums while I put her dildo in her vagina faster and hearing her moans excites me until I pour all my milk into her mouth and she swallows it all like the good whore she is.
