Sui is a colleague from when we first joined the company after graduation. We got along well among our peers and have always been close, but after we both got married and started complaining about our family lives, our affair began. We have great chemistry at work and in bed... and above all, she's incredibly beautiful. Today, we met at our usual spot. "You must be tired from work! The project was approved, so I'll give you a really relaxing day," she said, saying something cute that my wife would never say. We went to an izakaya (Japanese pub) and started our usual flirting, and today we headed straight to a hotel. I booked a room with an amazing night view, but she ignored the view and cutely begged, "Come on, hurry up, let's have sex?" While admiring her favorite black pantyhose, I inserted my hard cock, which had been erect since we were at the izakaya. She came lightly, convulsing just from the insertion. It felt so good that she was moving her hips herself, and it was adorable. I ejaculated deep inside her vagina until it overflowed. Today was a rare all-night session. Of course, it didn't end with just one round; they embraced naked and went for a second round... she thrust her hips herself, hitting her clitoris and squirting. An unstoppable affair of raw sex.
