There's something about this artist's artstyle that makes yukkuris look even more feeble than they normally are but I can't point out why. Maybe it's their small features; small eyes small mouth small braid and short hair, I dunno.
Also I commend this Oniisan for being so dedicated to abuse that he's willing to watch Maricha shake her ass for an hour every day, and even three whole hours for this particular day. Not to mention he's abusing other yukkuris too meaning he presumably also watches other yukkuri's daily ass shaking.
EndAs punishment for sleeping on your own accord, we'll add 2 hours to your ass shaking, now hurry up and get to itPy... pyesh...
Y... yes...PIGIIIIIIII!!Oi wake up you shitty manjuu
