Hentai Sex - Mou Hasamazu Ni Wa Irarenai Bonus

Based on the erotic manga by Kaizuka. An alien crashes into Amano Inori and, while repairing her body, accidentally makes her smarter, more athletic, prettier, and boosts her bust size by around five cups. The alien then requests to observe her, as he came to Earth to monitor humans in the first place, and does nothing to her until she notices Sugiuchi and Amano Inori getting horny. The extraterrestrial then manipulates Amano Inori's body, forcing her to begin having intercourse with Sugiuchi.
