Sword Art Online (2012)

A few kissing scenes throughout the show.

A female antagonist seduces one of the protagonists, then removes her clothes in front of him. Her hair is placed in such a way as to conveniently cover her nipples.

A girl is shown showering. It zooms in on her breasts but doesn't show nipples, and shows her whole body clouded in steam from the shower. Earlier in the episode, she is also seen in her bra and underwear. It zooms on her breasts in this scene as well.

A scene where multiple girls try to woo a boy and press their breasts against him and a few inappropriate comments are made.

A nurse flirts with Kirito (a little sexually too, asking him to strip for the electrodes that will monitor his vitals). He asks if he can only be shirtless for the electrodes, and she begrudgingly agrees that will work. He is shown shirtless as he is set up in the hospital bed. He also receives a letter teasing him about "being left alone with a hot nurse." The next scene shows Scion and her GGO avatar naked waist up with her nipples covered by her arms.

The camera occasionally guides the viewer's eyes towards Leafa's breasts in the Alfheim Online game. Suggestive themes via nonverbals, so to speak.

A girl, confused, implicitly offers to sleep with a boy; she is shown in her underwear. He denies the request.

A teenage girl falls in love with a teenage boy in a video game only to find out that it's her brother in real life and feels terrible.

Season 2. Kirito gets an avatar that looks appears female. He checks himself for breasts. He also imitates a female at a later point in the season.

In the 3rd season in the last few episodes theres a lady who is constantly naked, and fights naked, she conveniently has her hair cover her where necessary. At the beginning of these episodes she implores a boy to come lay with her while she is naked. The dialogue is very suggestive during this scene.

In the Alicization War of the Underworld section, episode 4 has a female character shown in undergarments and, toward the end of the episode, a man unleashes a power that rips off his clothes and he is shown naked, with his privates barely covered by things in the foreground.

In season 1 the main antagonist tears off a woman's top while she is handcuffed and chained with her arms above her head. he continues to touch her, kiss her forcibly, and lick her face. She tries to put up with it, but she is obviously terrified. It's made worse by the fact that the girl's lover is in the same room, subdued and forced to watch. It is obvious that he plans to rape her, and he continues his harassment while laughing sadistically. She begins to cry when he says that he will rape her again in the real world, as her real body is in a coma. This goes on for quite some time, and he manages to tear off a lower part of her dress as well, but he is eventually stopped and violently killed before he can go further. The purpose of the scene is to convey his sociopathic nature while simultaneously aggravating the audience and the main protagonist, but it is difficult to watch and extremely intense, easily the most intense scene in the series.
