As a personal trainer at a fitness gym, I offer special services to ensure my clients come back for more. Today, a plump, big-breasted girl came in for her first trial session, hoping to build strength and lose weight. I had her change into rental workout clothes, putting on tight, sheer leggings that left little to the imagination—her cleavage and the transparency created an intensely erotic atmosphere. Starting with light stretching to work up a sweat, I checked her core stiffness, then wore her down with squats and jump rope, gradually taking away her physical control as the training progressed. While she lay on the abdominal machine, I used "support" as an excuse to touch and massage her big breasts. She slowly began to feel pleasure, her breathing growing heavy, moans slipping out. Sitting her on the mat for flexibility exercises, I pressed my body tightly against her back, massaging her arms and large breasts. Sweat poured from her body, and she looked completely exhausted. Lying her down again, I massaged her thighs while sliding my fingers into her slit, stimulating her continuously. She gasped, "Ah, not there…", and responding to her reaction, I pushed deeper. Pulling aside her sports bra, I groped her bare breasts, pinching and teasing her nipples. Then, using my mouth, I intensified the erotic mood—sucking and licking her nipples as she cried out, "Aaaaaaah!" Next, I moved to butt massage, having her get on all fours, kneading her ass before removing her panties and licking her wet pussy. Her body twitched as she grew increasingly aroused. Then came oral training—blowjob practice, moving her mouth in rhythm with my count. On count ten, I thrust my cock deep into her throat for an intense deep-throat session. I thrust my hips into her slick, saliva-filled mouth, then pressed my wet cock against her breasts for titfuck instruction. Drool dripped from her lips as I told her to look up, delivering a deep kiss while violently thrusting my cock between her big tits. Pushing her into even harder training, she happily agreed, saying, "Yes, please!" Lying her down, I entered her from behind in missionary, grinding my hips. After three years without a cock, her pussy drooled and clamped down tightly. I pounded her relentlessly with deep kisses, her big breasts jiggling wildly as she writhed in pleasure. Sitting her on a chair, I took her from behind, making her rock her hips until sweat burst from her body. Pulling her up by the arms, I switched to standing doggy, slamming into her pussy. "Ah! Ah! Ah! I'm cumming!" she screamed. I kept thrusting hard into her pussy as she came in monkey style. Then, back on the mat, I had her straddle me, spreading her legs in a wide M-shape as she rode me. Pulling her close, I groped and sucked her breasts while thrusting up violently from below. "Miss Yoshida, how's my training?" I asked. "I-It's amazing! Aaaaah!" she moaned in delight. Keeping her lying down, I grabbed her hands like reins and pounded her hard, climaxing with a creampie inside her. Yoshida left after booking another vaginal training session for next month.
