Yukiho Shirase, petite and cute with F-cup curves, is a strict worker but loosens up after work, especially when wearing glasses! Her large breasts and muscular thighs make her miniskirt suit always tight. She's so sexy that I keep making mistakes because of her. As a reward for my efforts despite my mistakes, we have a private drink in the office after work, paid for by my senior. We get excited talking about erotic things, and I can't help but reach from her muscular thighs to her pussy because she seems unsatisfied with work. I tease her with cunilingus and handjobs, making her squirt profusely. Even when she finds the vibrator I've been hiding in the office, she's all game, saying, "It's a secret between us." After playing with the vibrator, we move on to her explosive breasts, with deep throat and blowjob. We have standing sex at the office desk, and then we move to various positions and spots in the office, doing intense piston movements. During the final spurt, she makes cute moaning sounds while targeting my nipples, making me extremely excited. We finish with a big climax, leaving the sofa covered in precum and semen. We clean it up with tissues before leaving.
