"Drink the semen that was deposited inside" has returned as a new project with a situation added! Yui, who heard rumors that sperm is good for beauty, wants to try it right away. But her boyfriend has been distant lately, so how can she get some sperm? That's right! She'll just ask the sister couple who are always having passionate sex with internal ejaculation for some of their deposited sperm. Hmm, maybe my skin condition is improving a bit! Then, her sister Rena also becomes interested, and the sisters start greedily sharing the semen.
