One day after winter break ended and school resumed, my niece was scheduled to visit my chiropractic clinic. Unexpectedly, her mother—my younger sister—came along due to a parent-teacher observation session. Though caught off guard, I decided to offer my sister a complimentary massage as well.
With my niece present, I couldn’t get too handsy, so instead I performed stretches and massages bordering on sexual harassment. Highlights include accidental panty flashes during leg stretches and her mother’s sensitive reactions when I touched her groin area. She’s especially ticklish around the inner thighs, reacting instantly whenever I brushed near.
During the session, we casually chatted about my niece’s future plans after graduation and everyday family matters, all while I continued the borderline inappropriate treatment. Once my sister’s session ended, she excused herself to return home for household chores—leaving me alone with my niece for the main event.
I began with regular conversation, standard massage, and stretching—mostly capturing panty shots at this stage. Then came something new: a low-frequency therapy device I’d secretly purchased for fun, not for actual treatment. I told her it helped with muscle tension and blood circulation, and she seemed genuinely excited.
I placed the electrode pads on her lower body to test her reaction. Surprisingly, she handled it well, even appearing to enjoy the tingling sensations. What can’t be conveyed through text or images is how erotically her soft, plump body twitched with each electric pulse—an irresistibly lewd sight.
She seemed to be enjoying it so much that she unexpectedly dozed off—completely unplanned. I had intended to take a break to serve tea, but this twist changed things. Unable to go too far, I gently touched her and shot close-ups for a while.
She wouldn’t wake up, so I considered pushing further—only for her to suddenly jolt upright. Time for a pause. I served tea and used the break before transitioning to oil massage.
She returned wearing paper panties and a paper bra, ready for oil treatment. This was the perfect moment to test the tea’s effects. Noticing her reactions had dulled, I slipped off her paper bra, removed her panties, and began massaging her entire body without restraint.
Next, I introduced a vibrating massager. The close-up shots of her pussy quivering—especially when the vibrator head is pressed tightly against her labia—are exceptional. There are even angles where her genitals are almost fully visible, barely hidden by the mosaic.
Then I re-applied the low-frequency pads—this time on her groin and chest areas—and turned on the current. (Neither of us are medically trained—do not attempt this.) Her body convulsed rhythmically around the pad sites. Her toes twitched involuntarily, and soft, erotic moans began spilling out.
Sliding fingers into her pussy, I found her already soaked. I aggressively moved my hand, combining finger thrusts with electric stimulation. She couldn’t speak clearly, but gasped “I’m cumming!” as her body spasmed through orgasm. Normally she arches like a shrimp when climaxing, but the electric current kept her body rigid—she came repeatedly while lying flat.
Next, I attacked her clit with a dedicated vibrator. Her reactions intensified—her whole body trembling as she soared through another climax, overwhelmed by combined electrical and clitoral stimulation. Watching her like this, I—her uncle—became uncontrollably aroused, climbing onto the massage table and mounting her in missionary position.
Just rubbing my hard cock against her pussy made her moan loudly, the wet slap of skin clearly audible. Pressing the clit vibrator against her while grinding, she climaxed instantly. Though technically just outercourse, her puffy labia spread wide, engulfing the head of my cock as if she were taking it inside.
Overcome with excitement watching her moan and cum repeatedly, I finally erupted in full missionary position, shooting load after load across her stomach and chest. Even after I came, she lay there drenched in cum, twitching under the low-frequency current—looking like a crime scene.
The video combines footage from two fixed cameras and a handheld iPhone. The first half features lighthearted, seemingly innocent massage scenes with my sister and niece (though still full of sexual harassment), while the second half focuses on my niece convulsing in pleasure from electric and vibrational stimulation. Enjoy the stark contrast between everyday life and erotic fantasy!
Additional footage of my older sister’s massage session is also in the archives—coming soon. MP4 video: 56 minutes 07 seconds, 1,920×1,080 (60fps).
