As a personal trainer at a fitness gym, I specialize in comprehensive training programs, and have successfully gained repeat clients through my special sex training menu. Today, I had a first-time client named Kobayashi. She looks demure, a typical gyaru girl. She told me she wants her butt lifted and toned like foreign women's, so I immediately started her on squats. As I had her raise her arms and perform wide-legged squats, I noticed her pussy ridge becoming visible through her pants, clearly stimulating my cock. When I demonstrated the squat myself, she noticed my bulging erection and asked, "Sensei, what's that?" I explained, "Exercise increases blood flow, that's why this happens." We moved on to abdominal training, where her pussy ridge again drew attention. While guiding her through push-ups, I supported her by groping her large breasts, continuing the workout. Next, we did high-resistance squats—pressing my cock against her protruding ass while fondling her tits—making her increasingly curious. "Sensei, is that big bulge real? It's fake, right?" she asked, growing more interested. As she actively grabbed my cock, I had her sit on the ab machine to begin training. I pressed down on her chest to increase resistance, and when she weakened, I fondled her breasts and pinched her nipples, drawing out strong reactions. During stretching, I massaged her bare breasts from her décolletage, making her moan in confusion. "Let's stimulate your female hormones through training!" I said, spreading her legs and rubbing her pussy ridge, prompting her to say, "This is our private session, you can make noise," after which she cried out, "Ah~ I can't hold it, I'm cumming, I'm cumming!" visibly excited. With her hips twitching, I went down on her, eating her pussy to intensify her response. Then, I finger-fucked her hard, making her thighs spasm as she orgasmed. While sharing deep, passionate kisses, I made her grip my hard cock, provoking more reactions. "It's huge! Are you training this too?" she asked. "This is muscle too!" I replied, then moved on to oral training. I made her open her mouth wide, take my big cock in, and lick along the underside, deepthroating it while drawing out her responses. I pressed her head down, thrusting my hips to force it deep into her throat, making loud gulping sounds as throat juices drooled from her mouth. I had her kneel and rubbed my slippery cock all over her big tits, exciting her further. Next, for lower body training, I had her grip the workout machine and stick her ass out. I plunged my cock into her wet pussy and started thrusting—Kobayashi screamed, "Ah, I'm cumming, cumming, cumming!" Her abs and arms twitched as I pulled her close and pounded her from behind. We moved to the mat for cowgirl position, where she spread into a wide M-shape, rubbing my thick cock against her clit, riding me with full enthusiasm. "It's been about five years, so it feels amazing," she moaned, swallowing my cock deep with a slick sound, grinding her hips back and forth, climaxing repeatedly. Then I turned her around for reverse cowgirl, thrusting up from below into her tight ass muscles, applying pressure to her pussy. I flipped her onto all fours and slammed into her from behind, making her entire body convulse as she orgasmed intensely. For the finish, I switched to missionary, hitting her most sensitive spot over and over, then pumped thick creampie loads inside her, telling her, "My special protein is being absorbed deep inside you." At the end, she asked, "Can I come again tomorrow?" I smiled and said, "Of course." Today, I've definitely gained a promising repeat client.
