That's so cute! She can't get out of the futon roll!

From original caption :
1 Playing rolled in futon-blanket.
2 Be found while playing such a kiddy act.
3 Try to make poor excuses.
4 "D,don't look me anymore!"

To be more precise,
1. Sanae-san playing, rolled up in a reed mat
2. Sanae-san being discovered, even though she thought nobody was around
3. Sanae-san thinking of excuses, "Ah, er, that is to say, um, this is...!"
4. Sanae-san turning red and saying "Don't look... don't looook...!"

Sanae has to go to Da Bathroom

Back when I was little, it was fun rolling around in a mat like that. Now I realized that my claustrophobia roots from those times when I rolled like that and stuck.
