After a few minutes of slow cocksucking, Sarah started to really pick up the pace as the man put his hand on her head and forced her to bob up and down on his big black dick. I could tell by his body language that he was getting close to cumming. 20 seconds later he quickly got up and repositioned himself so that he was jerking his cock right into Sarah's mouth. His breathing kept getting quicker and finally I saw his balls start to tighten up as the first spurt missed her mouth and hit right above her upper lip. He adjusted himself to make sure the rest of his cum reached her mouth safely. When it looked like he was finished, she put her mouth on his cock, sucking out of him whatever was left. This made her spill a little cum out of her mouth and drip down to her chin. He then removed his cock from her mouth, which gave her time to swallow the load that had just been shot in her mouth. She used her fingers to wipe up the cum on her face and then proceeded to lick her fingers clean too. I could barely contain myself as I could feel my own cock oozing what seemed like gallons of pre-cum in my pants.
She gave him a kiss on the cheek, thanked him, and headed towards the door. I quickly hid behind a clothing rack as she exited the office and headed back towards the front of the store. I was stunned. The woman who I was supposed to marry in 1 month had just swallowed a complete stranger's load. She hadn't even let me cum in her mouth on the rare occasions where she would suck my cock. She told me she thought cum was disgusting and made me cum in a tissue. Today, she acted like a total cumslut for a man she didn't even know.
I realized that she would probably be looking for me so I quickly headed back to the front of the store as well. When I finally found her, she had a big smile on her face as I played dumb and gave her a big, wet kiss. Boy could I taste that cum! We pulled apart from each other, smiling and I grabbed her hand as we walked out of the store together as a happy couple.
