This is a hentai-ish varition of this drawing:

SUMMER TIME - UZUMAKI KUSHINA

There are other two variations to this drawing:
Uzumaki Kushina is ready for summer (H-ish A)
Uzumaki Kushina is ready for summer (H-ish C)

Update:
I thought more about this and,
Since she's was originally wearing a bikini,
It would work better if she was tanned by the sun,
So this is why I updated this version, and the other too!

Let me know if this was a great idea, even more since...
