While shopping with my wife at our local Macy's, we split up to do our own browsing for clothes. Theresa needed a new dress for a party we were attending the following weekend. I knew to leave her alone for now. She always texted me when she had picked out a few things so I could give her my opinion. Not that my opinion ever really mattered.

As I browsed through the men's clothing section for items I really didn't need, my phone beeped with an incoming text. Glancing at it, I saw it was from my wife. She asked me to meet her at the dressing room in the lingerie department on the third floor.

"Lingerie department? I thought she was looking for a new dress," I thought to myself, shaking my head.

As I arrived at the dressing room, I did not see Theresa anywhere, so I assumed she was already in one of the stalls. There was no one else around, so I took a seat on one of the "husband" chairs and waited for my wife to pop her head out.

A few minutes later, I was scrolling through my phone when I heard a cough. Looking up, my eyes almost popped out of my head. There was Theresa standing outside the dressing room in just a pair of black lace panties, smiling at me. Her beautiful, firm breasts were completely exposed for anyone to see. Her nipples were already swollen and pointed.

"Are you just going to stand there, or are you going to come fuck your wife right here in the dressing room?"

She turned and reentered one of the stalls, shaking her sexy ass as she did.

My cock was instantly standing at attention under my trousers at this unexpected development. My wife had always been quite conservative with her sexual preferences, so a public rendezvous like this had never occurred before.

Before squandering this unexpected opportunity, I stealthily scanned my immediate surroundings. Seeing no one in the vicinity, I quickly headed into the dressing room and into the stall my wife had just entered, closing and locking the door behind me.

Without a word, she dropped to her knees and quickly unfastened my shorts, pulling those and my boxers down. My rock-hard cock dropped right in front of her face. Smiling, she licked her lips before taking my shaft fully into her mouth, swirling her tongue around my head.

As Theresa continued to bob up and down my swollen shaft, I smiled and thought to myself, "Who is this wench, and what has she done with my wife?"

As I started to quickly reach my release, Theresa stood and turned around, bending over the chair in the stall. Pushing her panties down her hips, they fell to the floor. Stepping out of them, she looked over her shoulder at me.

"Please fuck me, my dear. I really need to feel you inside me right now."

Not one to waste an opportunity like this, I shuffled up behind her, my shorts and underwear still bunched at my feet. Grabbing hold of my cock, I rubbed it up and down her soaked slit to lube it up before lining it up with her entrance and pushing it all the way inside her with a single thrust.

"Oh, my yes. Please fuck me hard. Claim me right here in the dressing room," Theresa moaned.

Still lost as to what had come over my wife, I obliged her demands with relish. I slammed into her with everything I had, grunting with each thrust. Theresa reached down and started rubbing her clit, whimpering as I ravished her wet and willing pussy.

"Oh, my God. You're going to make me cum," she cried out.

No longer concerned about who might be in earshot, Theresa moaned loudly with each of my thrusts.

"Fuck, oh, fuck. I'm cumming," she screamed out.

Theresa's body convulsed as her orgasm swept over her. Her pussy gripped my cock tightly, stimulating me even further as I kept plowing into her as she came. This was too much for me. I felt my balls tighten as I erupted inside of her, filling my wife's womb with my copious seed.

We both slumped over the chair. Our breathing was ragged as we struggled to catch our breath. My softening cock slipped from her still quivering pussy, my cum dribbling down her legs.

"Fuck, Theresa. What came over you? You've never done anything risqué like that before."

Theresa just smiled and said, "Well, as I was shopping for a few new bra and panty sets, I noticed a man watching me intently as I selected several sexy options to show you. He walked over and handed me a pair of black lace panties, the ones I was wearing when you first saw me."

He said, "I think you would look incredibly sexy in these."

Theresa was getting flushed as she told me what had happened. I could tell she was getting aroused again as she told me.

"What happened next," I asked quietly?

He gave me his business card and told me to call him once I was ready to model them privately for him.
