SDJS-209 — We Selected Female Employees With Big Butts! It Was Supposed To Be Just A Research Project To Develop A Masturbator For Butt-Jobs, But... We Inserted A Raw Dick To Compare The Sensitivity Of The Pussy And The Masturbator! We Thoroughly Investigated The Softness, Swaying, And Sensitivity Of Four Big-Butted Women!

SOD's female employee masturbation sleeve business. The new product we are developing this time is a big-ass masturbation sleeve! We conducted thorough research using four people with a reputation for having big butts as a sample survey! We measured their size and checked their depth using a dildo viewed from directly below. And in a comparative survey of the sensitivity of masturbation sleeves and pussies, you can see the brave figures of female employees who are embarrassed but can't help but feel pleasure!
