Yeah I can give a synopsis: The 'loli' girl is Yuuto, an old friend of MC's who gave him the drug in the first place. This chapter is about the MC, who has taken the drug a few times now and used it to get laid with both futayuto and his own sister, going back to Yuuto because he can't help but want the drug. Yuuto tells MC that he's too deep in, and won't want to change back ever again if he keeps taking it, which is what happened to Yuuto, who's now basically living full time as a girl. So Yuuto gives MC a choice: to walk away and forget about her and the drug's existence, or to be prepared to "live life as a girl and a whole other person." MC takes the pill anyways, and transforms into a much more erotic body than before, and then the two of them both get dressed as maids and start servicing a couple of guys, since as Yuuto says, the pills cost money too.
