No need for a scenario. Two girls from the Seitokai Yakuindomo series (no idea, ask wikipedia instead) give paizuri, head, have sex, and this is it.
The art isn’t even awesome, at first I thought it was only paizuri (it would have been better :3), but it still had a certain spontaneous charm, I liked it enough to want to share it. I reckon, the paizuris make for usable fap’n’go materials ^^;;
I slightly retoucehd the pictures BTW, see the end of the gallery for a before/after comparison.
