Stepping Stone
Just the usual Kano Shiuko lmao. Smut, stupidly funny, and untranslatable puns. Construction worker uke likes student seme's younger sister but seme says that his younger sister has high standards in men--must be tall (which uke is not), and has good academic background (uke got until middle school). Seme offers to be uke's tutor for his education but of course with payment--of sex. Then they fall in love with each other and we watch them struggle about their differences.
Abunage.
Seme is the Nakano fanboy from Otonage. And he surprisingly has such a big dick. His uke is their new full-of-himself foreman who has such a smooth, beautiful ass. And a tiny dick. Not that it matters anyway.
