I assist my neighbor in setting up a sexual encounter with a college student before giving her his penis to penetrate her untouched rear end

My neighbor and I have been trying to set up a sexual encounter with a college student for a while now. We've been texting back and forth, trying to find a time that works for both of us. Finally, we managed to coordinate things and she came over to his place. As soon as she arrived, my neighbor wasted no time in getting her undressed and on the bed, ready to fuck her. I assisted him in getting her ass ready for penetration, spreading her cheeks apart and dripping some water on her hole to make it more slippery. Once he was ready, he plunged his cock into her tight, untouched rear end. She moaned in pleasure as he fucked her hard, her big tits bouncing with each thrust. As he continued to pound her, I couldn't help but notice how fat and gaping her ass was. It was a sight to behold as he fucked her in the doggystyle position, tearing off her clothes and ripping her clothes as he went.
