Selecting female employees with big buttocks! Supposed to be a survey for developing a buttocks stroker sex toy… but ends up inserting a real penis for a sensitivity comparison between vagina and buttocks! Thorough investigation of the softness, jiggling, and sensitivity of the buttocks of 4 women!

There has been a flood of feedback on the new product, the Dekajiri Onahole, in the SOD Female Employee Onahole business. In particular, there are many comments related to Yuki Ishizaki, and voices of anticipation from her fans are rising. Additionally, there is a lot of praise for the approach to the project and the voluminous buttocks of the performers, but on the other hand, there also seem to be some requests regarding scenes to satisfy certain desires.
