PSTL-025 Koyama

About this work

#Personal trainer I'm a personal trainer at a fitness gym. I boost repeat bookings by using a private closed studio and “sex training.” Lately I'm so busy bookings are hard to get. Koyama came for a trial session. She says she doesn't work out, but being young she already has a fairly toned body. "This outfit might be too small..." Our shop's rental wear is extra-tight, shaping the butt, showing the mons' bulge, with a T-back panty visible through the erotic tight pants. We start with squats — making her stick out that sexy ass and hold a half-squat, then do sit-ups to drain the resisting muscles. "Sit-ups look tough, I'll assist you." I pull her up so her face brushes my crotch. "Keep facing forward!" Koyama looks embarrassed; I stop the teasing and begin stretching. I put her in an embarrassing flipped pose, bring my face close to her genitals, and touch her butt. "I-it's close..." "It's okay, it's just the two of us." I sit her on a balance ball and make her move her hips; her aroused pubic area rubs the ball. Under the guise of assisting, I grab her large butt and enjoy looking at her crotch. Prone, she lifts her hips into a cat pose; while supporting her I touch her breasts and push my hand into her crotch to tease her. "Muscles are tight, I'll massage them loose." Seated on the mat, I knead her breasts from behind and rub her mons through the tight pants. "Eh, wait..." I hug her and silence her with a deep kiss. "Now back to sit-up training." I offer my bare penis, pulling her hand so she takes it into her mouth repeatedly — abdominal fellatio. It's one of those moments I'm glad to be a trainer. "Yes, holding is important too." I pull her hands hard so she takes it to the back of her throat, and with irrumatio I thrust my hips to make her gag. I lay her on the mat, kiss while massaging her breasts, remove the bra and suck her nipples. "This is training too." I take off her tight pants, cunnilingus her and massage the inside of her vagina with my fingers. "Ahhh, no, I'm coming..." On all fours I make her stick her butt out and lick her shaven pussy. I flip her onto her back, make her do fellatio while fingering her. Koyama sucks while gripping my penis. I bridge her and attack with cunnilingus, then insert in missionary. "Let's train properly here." While tongue-kissing I piston, pressing her cumming pussy and pounding into the womb. Sitting on a chair we do face-to-face sex for hip exercise, then reverse cowgirl and front-back hip movements. I make her put her hands on the chair and drive in from behind while standing. I put her on the balance ball and fuck her hard from behind in unstable positions, then lay her on the mat for side pistoning. Back to missionary, I aggressively attack her repeatedly-climaxing pussy. "I'll inject my protein." "Protein?" With a breeding-press style thrust I piston violently and ejaculate plenty deep inside her pussy — a raw internal cum shot.
