His three lovely neighbors were like big sisters.
He longed to embrace them but couldn't say it, so the eldest slipped him a drug to relax.
The drug unexpectedly shrunk him from man to boy-size. Now he's cuter than ever!
Which of the sister should look after the reduced protagonist? He chooses the one
who runs hot and cold with kindness and fury, and his sweet babymaking life begins!

Severity can be love too!? This rather naive tsundere blonde with enormous breasts
can sting like a whip, but then she's dewey sweet and she lavishes love his throbbing member!
And her sharp attitude changes after the pregnancy.
Don't miss out on the hot, hot passion of such romantic mood swings!

Enjoy more sweeeet stories with these generous onesans!
