Atarimae Sex ~Ane to Otouto no Nichijou~

My older sister and I have been weird since we were little.

We were hiding things from mom. Things like kissing each other on the lips, letting each other see when we pee in the bathroom, and licking my sister's boobs in bed at night...
"Hey Touma... wanna taste my boobs?"
"Mmh... I can't taste anything, though?"
"If you keep licking it, you might be able to taste it better?"

We kept dragging out such a relationship, and even now my sister is...
"I'm taking the day off today, so I'll have you take it out again..."

One holiday morning while I was thinking of such things... I went downstairs to the first floor to see that mom and sis were, for some reason, being very noisy.
"Maho looks like she's going on a date today."
"Huh..."

That was news to me. Without me knowing, it seems sis got herself a boyfriend...?
And from that point, sis and I gradually started drifting apart...

Note: There's a minor jealousy inducing event in the middle — though it does not become NTR — so please be warned if this is not your cup of tea. This has a vanilla ending.
