A mother with big tits had a group sex with her friend after kissing

I really didn expect my stepmom to take the divorce this way... one weekend in Vegas with my sister and she turned into a real bitch! I think everyone deals with it differently, but I wasn prepared for what happened next. They behaved so unceremoniously that I had no choice: if they want my dick, they will have it! Well, I’ll have fun - no matter what they say!
