About this work
I'm a personal trainer at a fitness gym. I boost repeat customers by offering intimate sex-training sessions in a private closed studio. Today's client is Matsumoto, 20, with a cute smile who wants to build muscle. She has plump, very tempting breasts. While loosening her up with squats and stretches I enjoy how her tight pants have become slightly see-through and how the contours press into them. She hits her limit at ten sit-ups, so I support her by holding her hands. When she sits up I pull her until her face is close to her crotch. “I-it's too close!” “Keep your face straight!” She obediently follows and I lift enough that her face buries into the area. I put her on a balance ball, have her raise both arms and rotate her hips. Her panties are fully visible and the tight pants make her crotch and butt look very lewd. Prone, propping on her elbows, she raises and holds her hips. “No, my muscles are trembling.” “Okay, I'll assist.” I hold that sexy butt, lift her breasts from underneath and occasionally knead them. “Hey, you're touching me…” “It's fine, I'm assisting.” I seat her and check muscle tone from behind by feeling. “The chest is important too, let's train that.” I persistently massage her breasts over the bra. “Is this even training?” “Excuse me, I'll go direct then.” I have her raise her arms, slide the bra aside, cup her elastic bare breasts, and pinch the nipples. “Ah, wait!” “Stimulating the nipples helps prevent sagging.” I suck on her breasts and lick the nipples. “Ah…” I force a deep tongue kiss, spread her legs and rub her pussy over the tight pants. On all fours I have her stick her butt out, I rub the big butt with my hands, slip a hand into the tight pants and knead the flesh. “Nngh…” When I remove her panties an inviting butt appears. I spread the flesh with my hands and cunnilingus her beautiful pussy until her hips twitch with pleasure. “Now let's train the inside too.” I lay her on her back, spread her legs, finger her while licking the clitoris. “Auuuh!” Her hips thrust up — Matsumoto seems to come. “Next I'll train your face line. Open your mouth!” I shove my fully erect cock deep into her open mouth and have her move her hips like a mouth-slide. “Mmm…” “Now let's do sit-ups again.” As I pull her up I make her suck the cock — a sit-up fellatio. This pleasure is the trainer's reward. “Now let's push the lower part.” In missionary I insert my rock-hard cock into her pussy. “Nnnn!” I pull her hands back and piston hard toward the womb. “Ahh, I'm going to come!” I lift her trembling body, kiss with tongue and have sex in cowgirl position. “Now move up and down.” Covered in sweat and wet sounds, Matsumoto moves her hips up and down. “You're moving slowly so I'll assist.” From below I pound her pussy; even when she orgasms I don't pull out and force her to move forward and back. “Auuu, no, I'm coming…” Sitting on a chair I make her ride facing me, then place her hands on the balance ball and fuck her from behind standing. Matsumoto orgasms with abdominal spasms; I then put her on all fours and breed her from behind with hard pistoning. I press and thrust deep into her pussy, then from a side-back position I ram into the vaginal wall. “Can I continue like this?” “Y-yes…ah!” In missionary I hold her waist and thrust hard, finishing with a creampie inside her pussy.
