Also known as: コングラッチュレイプ
A 2002 adult manga book by Matsurioka Hideyuki. It contains the second part of his lifework(?) adult gag manga, "Re-ken (Rape Research)" series.
A scene in the book (page 47) has been parodied as a kind of Meme:

Obata Batako: ほほほほほ!! 何をされてもあなたなんかにイカされはしないわ!!
(Ha ha ha ha ha! No matter what you do, I won't come due to someone like you!!)
Batako: あたし最大の弱点である「両乳首後ろから同時こねくり」でもされない限りはね!!!
(As long my biggest weakness of "both nipples getting tweaked from behind" isn't exploited!!!)
Sekando Reeko: (tweaking her both nipples from behind, without a single word)
Batako: らめえぇえぇぇぇ うっかり…
(Noooooo~ Oh crap...)
