The red hair girl (Sakura) will be in the EXACT same blowjob pose and angle that the blonde girl is in. She will have the blonde girl's facial expression, but will keep her original outfit; she will also have lipstick like the blonde girl, except red (the same redness as her dress). The background can be really simple (artist's choice) and please change the original caption to:
"Damn! Who knew idols could make such a slutty face!"
(the format, font, etc. of the caption is up to you).
That's all, thanks.
