SDJS-193 It’s my first time working on a project like this. I’m trying to develop better dildos for men. Please let me test them using my own vagina. I’m a little shy, but I’m not shy at all when it comes to having sex with dildos. I’ve been working in the product development department for two years now. My name is Shizaki Haruka.

SDJS-193 Description

Taking the opportunity of appearing in AV films, Shibasaki Haru is determined to put her own efforts into developing new products. This time, she is working on finalizing the design of a new type of dildo for use in sexual activities. It’s all new for her: first-time experiences with all three types of sex! 1. “First-time Lotion Sex” – Researching lube for use with dildos, so that the entire body becomes slippery when using it. 2. “Cum Stretching & Fellatio at Close Range” – Studying how sensitive and shaped the penis is when it’s in close proximity to the dildo. 3. “First-time Sex with an Unsuspecting Man” – Comparing different prototypes of dildos and penises. 4. “First-time 3-Person Sex” – Observing how many thrusts are needed to achieve ejaculation during filming.
