I was just waiting for my husband to finish his shower when there was a sudden knock on the door. Thinking it was him, I opened it to find a huge, glistening cock belonging to Big Mack. Without saying a word, he pushed me onto the counter and began fucking my ass hard and fast. Despite the pain, I couldn't help but moan as he filled me up completely. The surprising intrusion ignited a fire within me, making me want more. With each thrust, I felt the tension build between my legs. Finally, with one powerful thrust, Big Mack's cock hit my cervix and I let out a loud scream of ecstasy as my orgasm washed over me. My pussy clamped down on his glistening shaft as I was filled over and over again by the giant cock that had unexpectedly found its way into my tight ass.
