MFT-005 When I Heard That The Biological Research Department Was Recruiting Sperm For An Experiment, I Was Hired Immediately And Was Overtaken By A Cute Science Female Member! Can you put out a little more?
由學校生物系女生髮起的“精子鞭毛活動”研究。 一名學校射精監測員被招募來提供實驗所需的男性精子。 我對如何提供很感興趣，所以我去俱樂部詢問...我立即被錄用並開始當場收集！ 一開始說的是用自慰器輔助射精，但為了收集實驗所需的精子量，行為不斷升級……按摩，神秘玩，自慰秀，cosplay雙腿性交， etc. 沒想到理科妹子這麼變態！ ！
