Working as a personal trainer at a fitness gym, I provide daily training guidance. My favorite word is "Muscle!" and for enthusiastic, motivated clients, I offer a special sex menu along with homemade protein injections—helping me boost repeat customers. Today’s trainee is Ms. Takeshita, who gives off a very celebrity-like vibe. She's been coming to the gym for a while and has finally decided to try personal training. When I ask about her workout gear, she replies, "I saw rental was available, so I didn’t bring anything." I respond, "Don’t worry, I’ll lend you some today for free," and she changes into a snug-fitting training outfit. She seems slightly self-conscious about how sheer the fabric is. "What should we do? Should I reschedule with my own gear?" I ask. "No, I’ll push through!" she answers, choosing slimming over shame, showing strong determination.
We start with squats to work her lower body. "Okay!" she responds cheerfully. After completing ten reps, I stop her mid-squat on the ninth, holding her in place to check her muscle condition. While she struggles to maintain the position, I aggressively massage from her inner thighs up into her buttocks. "Hmm, your butt feels kind of loose," I comment. We switch to abdominal exercises, doing several reps. "You look pretty exhausted—let me help." I grab her hands and lift her up, forcing her face directly into my bulging crotch. Taken aback, she quickly turns her face away. "I-It’s too close!" "Don’t be shy! Muscle! Muscle!" I keep pulling her hands, continuing the crunches as my cock throbs harder. "Ah, this is tough!" "Let’s stretch your hip joints then." I lay her on the mat and make her spread her legs wide, exposing herself in a vulnerable M-shaped split. "I-It’s embarrassing!" "Can’t you open wider?" I press down on her legs while using my thumb to apply pressure to the sensitive area near her pussy. "Ah!" she cries out. "Want to spread even more?" "This is my limit." "Then I’ll assist." I use my hard cock as a pillow while forcing her legs further apart, stretching her in this humiliating pose. "A-Are other people doing this too?" "Yes, you’ll get used to it." I make her assume the cat pose, sticking her ass out while stretching her lower back. I press down hard with both hands, kneading her ass cheeks vigorously—her ass is so hot I want to fuck it immediately. "Haaaah… this feels so intense…" "Are you married or anything?" "I broke up five years ago." I continue pressing and teasing the sensitive lines around her pussy, spreading her open.
"Now let’s check your pectoral muscles." I have her sit in a wide-legged position and begin massaging from her sides up to her décolletage, then her breasts. "Ah, that’s my chest…" "I’m checking your pectoral development." I vigorously knead her soft, large breasts, then slide her bra aside to stimulate her bare nipples. "Aaah, is this part of the training too?" "It’s personal training, after all." "But this is a little—" While groping her bare tits, I rub her pussy through her tight pants in the M-split position. "S-Stop…" I start fingering her directly, and her pussy quickly becomes soaked, making wet squelching sounds. "Your internal muscles are really tense. Let me loosen them up." I pull off her tight pants and continue the finger massage in the M-split, pussy juice dripping heavily. "I’m all messy like this—what’s happening to me?" "Sorry, I don’t know." "No worries. Now let’s move on to abdominal and oral training." I pull her hand and make her take my erect cock into her mouth. Pulling her head back and forth, I make her perform a rhythmic, pleasurable blowjob that doubles as ab training. On all fours, I squeeze her ass while making her suck my cock all the way to the base.
"Now, let’s use this to loosen your inner muscles." "Eh! B-But—" From behind, I forcefully thrust my rock-hard, thick cock deep into her pussy, pistoning in and out to loosen her stiff vaginal walls. "Aaaaah, wait…!" I press her head into the mat, grab her lifted ass, and pound deep into her pussy. "Aaaaah, no! Stop!" "Good job, Takeshita—you’re sweating nicely now." I lick the sweat off her ass cheeks and switch to standing doggystyle against a machine, engaging in sweaty sex. I suck her sweaty tits while fiercely thrusting into her pussy. "Aaaaah, sensei… I’m cumming!" "Now, time for oral training." Not circuit training—but circuit sex. I make her give me a blowjob, then switch to missionary-style cowgirl, making her ride me. "Don’t just move up and down—sway your hips forward and back too." She grinds her horny pussy against me, milking my cock with her undulating movements. Then I switch to rear entry, hammering her cervix hard. "Sensei, no, I can’t! Aaaaah!" Her abs spasm violently as she orgasms. I keep thrusting into her cum-filled pussy, rubbing my cock against her sensitive insides in missionary. "What do you want? This?" "I-I want it." I bind her legs together and pound deep into her pussy, making her moan wildly like she’s lost her mind. "As today’s reward, I’ll inject you with protein!" I violently thrust into her open, M-shaped pussy and creampie her, shooting my sperm deep inside. "Make sure to book your next session—we’ll continue from here." "Yes, I’ll do my best." And so, Takeshita releases five years’ worth of vaginal detox and becomes a repeat customer.
