SNOS-050 | On a hot spring trip with my girlfriend and her sister, whenever the sister is alone, she gets all sweet and intimate with me, touching my body and begging for a kiss. When I get an erection, she starts sucking my dick, slurping it up, and fucks me in all sorts of positions until I ejaculate in large quantities at will. Kawagoe Niko

Instead of mom, I'm going on a hot springs trip with big sister and her boyfriend!!!
Big sister's boyfriend is Nico's type...
If that's the case...I'm really sorry, big sister. I'm going to steal Nico away.

I'll touch her body all the time, touching her through the fabric!!
I'll touch her while sightseeing, under the table, in the elevator~
See, your boyfriend has started to notice you!

Then the rest is easy.
Look him in the eyes, act sweet...and then it's okay to kiss him.

I'll lick his whole body while I look at him, and make his penis feel good in positions he's probably never tried before.

He's already crazy about Nico.
