[Satou Mitsu (Ebi Omitsu)] Supposedly There's A Secret Cumsuckery Club At Our Academy... [ADTL]

Two busty schoolgirls secretly run an academy club devoted to draining teachers who can't be honest about their desires, subjecting them to slow teasing handjobs and breastplay where finishing is forbidden until they grant permission. One guilt-wracked sensei keeps swearing he'll never return, yet each visit ends with a satisfied girl licking his seed from her fingers and purring about how much he came, until his restraint finally snaps into desperate, sweaty sex with one of them that leaves her moaning that she'll cum. By the end the pair are promising lots of club activities to make his dick stronger, turning his weakest after-school hour into their favorite playground.
