For those who didn't MTL this, the story seems to be that the protag felt empty and wanted to find something to get her going, so she hooked up with an old bastard. It was apparently disappointing. The delinquents saw her get into love hotels, and blackmailed her, which was only midly exciting. She begs them to tickle her, and they realise that you have to tickle her silly to get her going (see pg12 lol). They then oblige. Not really much story dialogue after that, they just say some usual lines, and she realizes she's a tickle addict or smthing like that. Ends with her hoping for another session. P.S. It seems like the Japanese slang for vanilla is "tuna"? I got no other idea for why it spat out that word so much.

Bullshit. You're telling me that after that long tickling session, she managed to stay on that desk without falling?

tickle sex is the best sex
