This installment of "Acrobatic Sex!" features Yumi Otsuka, a sweet, masochistic girl who absolutely loves electric massagers. Her cute Kansai dialect adds charm, and her expressive voice instantly sets the mood—her allure is irresistible. Her experience with special sex positions is limited to basic ones like missionary or doggy style. While she has experience with watersports (both giving and receiving), her submissive nature means she actually prefers being the one to pee on her partner. Her favorite position is doggy style—mainly because she loves using electric massagers, and that position makes it easiest to target her sweet spots. Her erogenous zones are her nipples, back, and clitoris. She especially enjoys having her nipples rubbed with the tip of a fingernail—so sensitive they harden instantly with just a light touch. Her body is extremely responsive, easily brought to orgasm by an electric massager. She loves clitoral stimulation, whether from a vibrator or cunnilingus. We begin our session by focusing on her sensitive areas and preferences. Fingering her clit leads to intense squirting, soaking everything. As we loosen up her pussy, we prepare for acrobatic creampie sex. She reaches orgasm more easily with the vibrator when lying on her back with legs wide open, rather than in a split position. Since backbridging is too strenuous right after climax, we try flipping her over and applying the vibrator from behind. Just lifting one leg while stimulating her from behind has her moaning cutely, exclaiming, "Oh no… this is bad…"—overstimulated by her favorite toy. Did we make her cum too much already? No matter—her pussy is perfectly ready! Now, enjoy acrobatic creampie sex with Yumi, the girl obsessed with electric massagers! Watch her squirt uncontrollably from vibrator stimulation! (Warning: extremely loud orgasms—please mind the volume!)
