[Half price -- 330 yen -- for the first 28 days from release]

For you, an office worker who goes to a personal gym on the way home from work. Your trainer is 24. After closing, in a fully private room, all you do is lie back.
One round per set, five sets in all -- squat cowgirl, grinding, interval edging, reverse cowgirl and close-embrace cowgirl: 5 different cowgirl styles, 5 creampies.
She counts your reps, praises your form and cheers you on. No missionary, no doggy style -- cowgirl only.

Three months since you joined. You wanted to do something about the back that desk work keeps wrecking, so twice a week you visit a fully private personal gym by the station. Tonight you have the last slot before closing. At the counseling desk, looking over your body-composition results, Natsuki smiles -- "Your body fat's down. Nice!" -- then suddenly lowers her voice.

"By the way... Lately you've been watching me in the mirror, haven't you? Especially during squats." Busted. But she isn't angry. "I've been pretending to check your form and looking at you plenty, too. So we're even." "It's after closing, so nobody else is coming. ...Want to try a special menu?" "A lower-body workout. Except today, I'm the one doing the work, not you." If you'd rather not, you'll just stretch and call it a night -- you nod, and she asks, "...Really?"

Partner stretching up close on the mat, "breathe in, breathe out" right in your ear. She catches you getting hard, straddles you, and grinds against you through her bike shorts (spats) as a warm-up. She asks once more, "Can I put it in?" -- then slowly takes you all the way.

Set one is squat cowgirl. She counts up three rounds of ten, moaning, "...Ten. Cum inside me -- all of it." In set two, the grind, the trainer cums first, and her squeezing tips you over the edge before you're ready -- round two. "Next time, I'll keep proper control." Set three is intervals: ten fast sprints, then hold still while she counts to five. Hold back through two edges, and on the third: "Okay, cum. Now."

After a break with protein and sweat, set four is reverse cowgirl. Showing off the butt she built with squats, she looks back: "Look at me. Cum." The final set: chest to chest, arms around you, counting down from ten to zero in your ear. "Zero. ...Let it all out." The biggest one comes last.

Counting, praising, cheering you on -- a night your personal trainer drains every last drop out of you, riding you five times.
