My naked athletic body bounced back and forth as he viscously fucked me from behind. My large breast swung back and forth in rhythm with his pumps. My...little bald slit was wrapped so tightly around his cock that I could feel his veins pumping blood to his large cock. "Fuck that tight bitch", the man holding the knife yelled. I looked over at him he was now completely naked and jacking off while he watched this dog fuck me. I was so humiliated that a dog was getting to enjoy my young naked. "Reward her with a drink now Krista." The man ordered."What? Me?" Krista said surprised."Of course I mean you! Now do it before I decided to marry you to my dog!" The man said impatiently.This startled Krista. She waddled over to her sister and sat down on her face. Parting her labia she focused on peeing. Her sister now defeated and motionless simply accepted what was happening while Krista let out a small stream of urine yellow as apple juice. Sierra swallowed multiple times as a reflex to. We took the elevator and entered.Eric tells me: You make me hard as a bull. Just looking at your mouth, I want to put my penis in it. Suddenly, he opens his pants to show me his penisThe elevator arrives on another floor (5th), he knows it stuck behind me to press me against the metal doors, I press the emergency stop button, drop my bag and he rubs his big hard cock on my beautiful round ass ...!I struggle, he keeps me firmly glued to the elevator doors, he slides his penis between my buttocks. This always got us very turned on in bed and gradually we realised that we would love to take a step further and actually do more than just fantasise. Especially as Jay expressed a deep desire to finding out what it would be like to be with another woman. I was definitely all for going along with that one. It’s been a few years now since we took that first step and have since met with some really lovely couples where the female partner has the same inclinations. Anyway, as it happened, Jay.
