While this is one of the CLOSEST to sex scenes we get in the whole show, it’s just too funny and disturbing to place any higher. In this scene, Setsugen no Ao decides to hijack the student assembly to get the kids thinking about sex. She makes use of the horny flies studied by Hyouka, a strange but terribly smart student who yearns to understand how babies are made. Setsugen plays a video of the flies going at it while dubbing over the buzzing with extremely clichéd lines you’d hear in any porno. Despite it being bugs on screen getting it on, and Setsugen doing both the male and female voices, the students find themselves curiously turned on. They don’t even know what they’re viewing is ‘sex’ yet the visuals and Setsugen’s lewd lines have them shaking and grabbing at their privates.

Anna, the pure student council president and crush of Tanukichi, has recently developed feelings for Tanukichi she has never experienced before. She wants to see and touch him all the time, and certainly, that must mean she's in love!! Understanding nothing of her own body or drives, Anna interprets everything as displays of ‘love'. When these feelings get too strong, she makes some cookies for Tanukichi. He notes they taste a little different, and that is when Anna reveals that when she thinks of Tanukichi, ‘love nectar’ comes out from between her legs. What better way to show her love to him than by including this nectar into the cookie batter? Tanukichi’s face is something to behold, but so is Anna who starts grinding against the corner of the table. She is staring Tanukichi dead in the face as she masturbates in front of him, having no idea she’s just REALLY suppressed and horny and thinking she’s just innocently showing her love for him. She turns out to be a real yandere, super sweet but stalkerish when she’s apart from Tanukichi, and she goes to some crazy lengths to make Tanukichi hers!

This particular moment is special because we get both guy on girl AND girl on girl! The students at Totsuki Academy end up at a public bath after a number of disturbing events. Setsugen relaxes with fellow Sox members Kosuri and Otome in the girls’ bath while Tanukichi waits for fellow male student Goriki in the boys’ bath. Setsugen has a pretty bangin’ body which catches Kosuri’s attention. Being the impetuous, dirty-minded girl she is, Kosuri starts praising Setsugen’s nice body and full breasts, at first just touching them lightly with her hands. Setsugen objects but Kosuri then begins motorboating her senpai’s boobs and fondling her vigorously despite Setsugen’s sexy pleas to stop. Tanukichi can’t help being aroused by the sounds but welcomes what appears to be Goriki entering the bath. Once he feels giant titties on his back, he knows that Anna has somehow found her way to him again. She threatens him to be quiet lest the others should hear and fondles him all over. When it becomes too much, she pushes her crotch down on Tanukichi’s face and goes to try his ‘love nectar’. It looks like Tanukichi might be saved when a scream brings everyone outside, but Anna simply drags him along by the dick to figure out what the ruckus is about.

Trying to save his skin from a very jealous Anna, Tanukichi pretended that the reason he went to see Hyouka (remember the fly girl?) was to ask her opinion on a present he had bought for Anna. In reality, he had asked the savvy scientist to create some tiny capsule shaped vibrators, but having nothing else on hand, Tanukichi had to pretend that was the gift. Fast forward and Anna has fashioned this supposed ‘powerstone’ into a necklace with a long chain, it slips between her boobs as the controller breaks, causing it to vibrate endlessly. Anna assumes this strange feeling must be the powerstone increasing her love and dives onto Tanukichi. The vibration is so powerful her shirt bursts open and her vibrating boobs are laying on top on Tanukichi’s crotch. Even through his clothes, the sensation is so strong he feels he might ejaculate at any moment. Anna's continuous moans and lewd phrases only push him further, with hilarious imagery to accompany his inner torment.

Tanukichi ends up accidentally kissing Anna while trying to save her from a violent stalker, and hasn't seen her in days. He goes to sleep depressed one night assuming Anna hates him but he soon learns that's not the case. Anna comes in, immediately binds him and covers his eyes with her panties, and then strips down naked while sitting on top of him. She muses that she's never felt so strange before and reasons it must be love! Ever since their faces touched she'd been overcome with a strange feeling she didn't know how to release, but she feels relief at touching Tanukichi. Her overbearing attempt to be closer to him is peppered with moments where she is confused at what's happening, only to feel another powerful surge inside her. We all know what it is, but Anna has no clue and as a result, is completely swept away. Poor Tanukichi tries to resist the strong naked woman on top of him but it looks like his virginity will be forcibly taken away until someone walks in!
