We finished our drinks and left the coffee shop. This is usually the point where the woman thanks me for the coffee and then I never see her again. Bu... this time was different. I walked her to her car and when I went to give her a hug, she kissed me. Not a quick peck but a full-on passionate kiss. For a second, I was taken off-guard but leaned into it as her lips felt amazing. We stood there together in the parking lot making out for what felt like forever, oblivious to the world. Her kissing. .. I mean... Chantelle told me, Sir." You mean, Mistress Chantelle." Slap!"Mmmmmm... Y... Yes, Sir. Mistress Chantelle. Sorry, Sir. Um, Sir?" She was almost panting. "Sir... the best way of course, is um, is directly on the skin, panties down... that way you can see... see... exactly what you are doing." You mean just pull up the hem of your dress, and pull down your panties?" If I'm wearing any, Sir," she giggled."This is great fun. I always wanted to do this." As much as I was enjoying this. “The punishment depends on the severity of the cheating. In this case…” Mandy thought for a minute, then giggled. “In this case, I’d say fifty swats on her bare bum.” I couldn’t believe my ears. My best friend was collaborating to spank me with these girls! “Don’t you think it should be fifty each,” Liz asked in return, “after all, she has cheated every one of us who has played her round?” All the girls agreed while I wiggled and squirmed in their grasp. Suddenly, Mandy’s face was right in. I pulled out slowly as she was still sucking on his dick and licking his balls. I went to go shower and as I walked back through I saw that she was riding him. I leaned in and said my goodbyes as I headed out the door.While at work, I kept checking my phone to see if she had sent me anything. At around 9:30 she sent a text photo of her pussy with cum leaking out of it. She said they fucked a couple of times before she dropped him off at his practice. I was so excited to get home. I thought.
