Caught sister and her friend masturbating, and I fucked them

I was watching my sister and her friend playing in the bedroom, kissing and fucking their teen pussies with dildos. When they saw me spying on them, they told me to join them. How could I say no to two sexy girls that I have been dreaming about for a long time? Watch the two horny sluts share my big dick, and I fucked them so hard that they screamed with pleasure. I guess having a real dick inside your pussy feels better than a dildo, no?
