5 – the sailor uniform. what a classic entry. the cut off top shows off her excellent, flat tummy for brotherly enjoyment. meanwhile, the short skirt allows for quick glances of the precious treat underneath

4 – you might not think of little sisters when you think of the bunny outfit. but the unorthodox nature of the garment makes it even more appealing! while other onii-chans are obsessing other other forms of clothing, you get a personal show from your bunny cunny sister wife!

3 – wedding dress. this is peak fertility territory. imagine marrying your sis, just to pin her to your bed and make her yours! all in a pure white wedding dress! plus, the soft gloves would allow for excellent handjobs.

2 – the swimming costume. the swimming costume hides very little. but it still hides enough so that the mind has to work a little bit to fantasise. its the perfect amount of stimulation!

1 – no clothes at all. some might say its a bit cruel to make your sister not wear any clothes. but i think different! with a body like kirino’s putting clothes on it would be a waste! to hide that perfect figure would be nothing short of insult!
