Γαμάω την ετεροθαλή αδερφή μου στο ντους και μου ζητάει να γεμίσω το στόμα της με χύσια

I go into the bathroom while my stepbrother is taking a shower. I masturbate while watching him and then ask him to fuck my tight pussy. He makes me moan with pleasure until he cums inside my mouth... how I like to swallow his cum
