#PersonalTrainerI'm a personal trainer at a fitness gym. Our private studio and intimate sex training are helping to increase the number of repeat customers. Today's customer is Matsumoto-san, 20, who has a cute smile and wants to build muscle. She has plump, delicious-looking big breasts. While loosening up her body with squats and stretching, I enjoy the transparency of her tight pants and the way her pussy muscles dig in. She can only do 10 sit-ups, so I support her by pulling her hands. When she stands up, I pull her until her face touches my crotch. "I'm so close!" "Keep your face straight!" The obedient customer pulls up until her face is buried in my bulge. I make her sit on a balance ball, raise her arms and rotate her hips. Her panties are completely visible, and her crotch and butt in her tight pants are super erotic. She lies face down, props up on her elbows, and keeps her hips raised. "No. Your muscles are trembling." "Then I'll help you." I hold her sexy butt, lift her big breasts from below, and occasionally rub them. "Eh, I'm touching you..." "It's okay, I'm helping you." He makes her sit down and palpates her muscles from behind. "Your breasts are important, so let's train them too." He persistently kneads her breasts over her bra. "Eh, is this training?" "Okay, then, excuse me." He makes her raise her arms and pushes her bra aside, kneading her bouncy bare breasts and pinching her nipples. "Ah, just a moment!" "Stimulating your nipples will help prevent them from sagging." He sucks her breasts and licks her nipples. "Ah, ahhh..." He forces her to French kiss him, spreads her legs, and rubs her tight-fitting pussy. He makes her get on all fours and sticks out her ass, rubbing her big ass with his hands, then thrusts his hand into her tight pants and kneads her butt. "Ahh..." He takes off her panties and reveals a delicious-looking butt. He massages her ass cheeks with his hands, and licks her beautiful pussy with cunnilingus, making her hips twitch in pleasure. "Now let's train the inside too." He makes her lie on her back with her legs apart, and licks her clitoris while fingering her. "Aaaah!" Matsumoto thrusts her hips upwards, and it seems she has come. "Next, I'll train your facial line. Open your mouth!" He thrusts his rock hard cock deep into her open mouth, and shakes his hips while using it as a mouth pussy. "Mugugugu...!" "Now let's do some sit-ups again." He pulls her hands and makes her suck his cock as he stands up. This feeling is the ultimate reward for a trainer. "Now, let's work on the lower part as well." He puts her in the missionary position and inserts his rock hard cock into her pussy. "Hmmmmmm!" He pulls her hands back and makes a violent piston movement towards her uterus. "Ahhh, I'm cumming!" He picks up her body, which is spasming with orgasm, and has sex in cowgirl position. "Now, let's move up and down." Matsumoto, covered in sweat and making a sticky noise, moves his hips up and down. "You're moving slowly, so I'll help you." He thrusts his hips back and forth without pulling out even when she cums. "Aaahhh, no, I'm cumming..." He makes her sit on a chair and have sex in face-to-face position, and then makes her put her hands on the balance ball and thrusts her from behind. Matsumoto, whose stomach is spasming with orgasm, gets on all fours and pistons her from behind. He presses her and moves her pussy deep inside, and then pounds her vaginal wall in side position. "Can I continue like this?" "Y-Yes...Ahh!" He holds her waist while having sex in missionary position, pistoning her hard, and cums inside her.
