konata is so lucky she got both sisters

Lucky? Unless she can turn this into a threesome there may be blood

"Okay, I KNOW this looks bad, but I have a perfectly good explanation for this..."

"Oh, you'd BETTER!"

caught cheating and potential NTR, she might have an anime reference to escape

That's a good glare from Tsukasa.

Just have a threesome, seriously. :3

Didn't this happen in Clannad?

Schoooooool daaaaaaays

Don't worry, people. Tsukasa will fall off the ground, bleed to death and then everything will return to normal.

School days? I remember that there was a bloodbath at the end. But I don't remember why... In the russian version cut out all the sex scenes but left the blood.

Suddenly Tsukasa seems not so air-headed and innocent D:

Tags edited to include parody and catherine (game).
The picture's title on Pixiv is キャサ☆リン = Cathe☆rine. This is a reference to the scene where Vincent wakes up with Catherine in his bed and Katherine walks in on them. The fact that Konata is wearing boxers similar to Vincent's also implies to this reference, too.
