#PersonalTrainer I'm a personal trainer at a fitness gym. Our dedicated, closed-room studio and stealth sex training have increased our repeat customer rate. Yamada-san, who visited our trial class after hearing about us, has a refined, feminine figure. We had her change into rental see-through tight pants and begin the workout. Squats are an important exercise for sapping resistance muscles. I have her cross her arms over her head and lower her hips deeply. The sight of her panties showing through her tight pants is always erotic. Next, we move on to abdominal exercises, a weak spot for women. While supporting her, I pull her hand and raise her face right up to her crotch. "You're so close..." "Your muscles are getting hard, so let's stretch." I have her lie on a mat and make her assume an embarrassing pose, supporting her while touching her large buttocks. "Now, I'm going to check all of your muscles." I have her kneel and massage her breasts. "Um... just a little..." "Please let me know if there's anything you're concerned about." "No... it's fine." I remove her bra, suck on her breasts, and share a passionate kiss. "What if someone comes..." "It's a completely private room, so it's okay." He makes her lie down on the mat and rubs the crotch of her tight pants, then inserts his hand into her panties and fingers her. "Ahhh!" He makes her get on all fours and takes off her panties, licking her smooth ass and attacking with cunnilingus. "Ah, come on, teacher, no!" He spreads her legs and attacks her wet pussy with his fingers. "Ah, ah, no. I'm going to cum." Yamada twitches and convulses as she cums. "Can I keep going like this?" "Y-Yes..." "Now, let's train your mouth." He makes her stand with her legs crossed and puts his bare cock in her mouth, performing a no-hands blowjob. "Use your tongue and stroke back and forth." He enjoys a satisfying, obedient blowjob, then trains her abdominal muscles again. He takes her hand and makes her suck his cock every time she stands up, attacking her throat. "To finish off, let's train all the muscles in your body." He makes her lie down on the mat and thrusts his cock deep into her in the missionary position. "Teacher, that's not okay! Ah..." He thrusts rhythmically into her sloppy pussy with deep strokes. "Ah, ah, ah, ah!" He rubs her swaying breasts and french kisses her while vigorously pounding the depths of her pussy. He sits on a chair and has sex in the cowgirl position. He instructs her on the pounding motion of his rock-hard cock. "Ah, no, I'm going to cum!" Yamada's ass cheeks twitch and spasm as she cums. He grabs her ass cheeks and makes her swing her hips back and forth, then squats in the rear-entry cowgirl position. He pounds her cumming pussy hard. He makes her put her hands on the balance ball and fucks her from behind. "Let's try our best not to move the ball." "Ahhhh!" He changes positions and pounds into her pussy, which tightens as she tries to maintain her posture. He puts her on all fours and pounds her hard from behind. Yamada cums over and over again, letting out a cute moan. "Ahhh, that feels too good!" He pulls her arm and thrusts violently, then lays her down on her side and thrusts into her in side position. He spreads her legs and licks her pussy with cunnilingus until she cums, then inserts his dick in missionary position. "Aaaah!" "The more you cum, the tighter your body gets." He picks her up and makes her squat in face-to-face cowgirl sex, then puts her back in missionary position and thrusts again. "I'm going to inject some protein into you." He thrusts violently into her pussy and pours his semen into her with a raw creampie. "Today's trial class is over. Please register as a full member." "Okay, I understand." Having gotten a taste of sex training, Yamada started attending once a week.
