Mei: (thinking) What? Tongue?! You can do that? (speaking)Pretty impressive.
The kisses Griffith gives to Princess Charlotte prior to engaging her in sex carry this energy; they were kisses fueled by frustration and despair over Guts leaving the Band of the Hawk, and he was desperate for some form of solace. Charlotte, who is in love with Griffith, is hesitant due to his sudden advance, but ultimately complies and lets him take her.
Then it's played for sheer horror when Griffith, having been reborn as Femto of the Godhand, crosses the Moral Event Horizon; he forcefully kisses Casca as he's viciously raping her in front of her lover Guts. As a finale to this heinous act, he forcefully tongue-kisses her as he explicitly rapes her from behind, making sure Guts sees every detail of what he's been doing to her.

Rimris forces a kiss on Vald while propositioning him. Given that he's in love with Havi (not to mention that Rimris had him tied down and he'd just escaped an Attempted Rape), Vald is less than receptive.

In another very rapey instance, Embryo gives Ange a somewhat forceful kiss as he attempts to brainwash and seduce her. Too bad for him, Ange remembers her First Kiss with her Love Interest, Tusk, and regains her mind to rebuff Embryo for his advance... all it does is impress him further.
Dawn of the Arcana: Caesar pulls forced kisses on Nakaba in the first chapter.
DARLING in the FRANXX has Unlucky Childhood Friend Ichigo forcefully kiss her crush Hiro on two separate occasions. In the first, it's pretty much an attempt to mimic the kiss between Hiro and Zero two, in the vain hope of achieving similar results. On the second, she accompanies it with her Anguished Declaration of Love.
Hiro is subjected to this again by the Klaxosaur Princess, who traps him in her Combat Tentacles and forcibly takes him as her Stamen. There's nothing remotely romantic about it, and Hiro struggles the whole time.

Leonard does this to Kaname in Full Metal Panic! during their first meeting. Kaname gets really pissed at him for stealing the Sacred First Kiss that she wanted to be with Sōsuke.
Sōsuke unintentionally delivered his own to Mizuki much earlier when posing as her boyfriend, after Mizuki's very incredulous friends insist she "prove" their love by kissing. Mizuki immediately balks at the idea. Sousuke, however, ascribing no sexual or romantic significance to mouth-to-mouth contact (and associating it CPR more than anything), simply does as he's asked and plants one on Mizuki despite her obvious disinterest. He is appropriately rewarded with a punch to the face by Mizuki and an angry lecture on consent from Kaname.
Season 1 has Fiery Red Head pilot Nena Trinity giving one to Setsuna the first time they meet, much to the latter's disgust since he Hates Being Touched.
Season 2 has Lyle Dylandy giving this to Feldt Grace. Justified, as he made the move to stop people comparing him to his twin older brother Neil - the first Lockon Stratos. In Feldt's specific case she had a huge Precocious Crush on Neil, who would've never forced a smooch on her; by forcibly kissing her, Lyle sorta told her to not use him as a Replacement Goldfish for her lost First Love.

Naruto: During an anime-only filler arc, Naruto received this in a form of a Kiss of Death (a kiss that sucks chakra out of your system) from a female villain named Fūka. She successfully forces a kiss on him three times, but none of them completely work due to various reasons.
First, shortly after encountering each other for the first time, she pins him against the wall while aggressively flirting with him and claps his cheeks together to get him to hold still and pucker up. She passionately makes out with him for several seconds, but realizes that she actually kissed one of his Shadow Clones, allowing Naruto to survive.
Second, at the end of their first fight, Fūka manages to immobilize the real Naruto by turning his legs to stone with a paralysis jutsu. After taking a moment to continue her faux flirting with him, including cuddling with him and holding him by the face to force a mock romantic Held Gaze between them, she successfully kisses him and begins draining his chakra. After awhile though, she accidentally ends up absorbing chakra from the Nine-Tails, and due to it being too "evil" for her, releases Naruto and shoves him away, returning his chakra to him.
Third, she knocks Naruto out during their second fight, and remembers that he has wind nature chakra and decides to stock up, lowering herself on top of Naruto and kisses Naruto while he is unconscious. She spends too long fantasizing about having his power for herself though and draws out the kiss too long, allowing Naruto to wake up and realize her weakness, and he breaks the kiss before she can get his chakra.
Since a kiss on Negi is required for a Pactio and Haruna really wanted the Artifact that comes with the Pactio, she does this on Negi. Twice.
Evangeline once forced a kiss on Negi too, "as a fee for her advice. Asking favors from an evil mage always requires payment."
There is also the part with the multiple fake Negi: One of them tries to forcefully kiss Yue, and explodes after she repels him. Said fake, named "Nugi", makes a reappearance as a golem that Haruna made for the girls to practice their Pactio kisses on. Naturally, it doesn't go as planned, and Akira suffers for it.
There was also that whole "Wish made too close to the power-leaking world tree turns Negi into a kissing Determinator" incident, where Negi gave a Forceful Kiss to Asuna.
And then there's the multi-page Pactio by Negi to Chachamaru. Negi's forceful kisses break laws of magic!
In chapter 252 Konoka gives Setsuna one of these for their Pactio.
Also used by Negi towards Shiori alias Luna. Her cover as the fake Asuna has just been blown, and he'd rather kiss her and undo her disguise than having her non-lethally shot by Mana.
Asuka goads Shinji to kiss her. Though, given their neuroses and insecurities, the process ends becoming up very awkward. She doesn't want to seem interested in case he turns her down, so she tells Shinji to hold his breath as it is tickling her, before she, much to his surprise, pinches his nose shut and forcefully kisses him. Shinji wants to kiss her back but he doesn't dare to because he can't believe she likes him. Asuka then holds the kiss (and Shinji's nose) for so long, waiting for a reaction, that Shinji almost ends up being suffocated by it. This was brought up again during the infamous Mind Rape scene. When Shinji came up in her head, she exclaimed "What are you doing there?! You won't do anything!You won't help me! You won't even hold me!" And it's shown that after their first kiss, she ran to the bathroom to gargle so she could hide her pain from him about his lack of warmth.
It's implied the Elevator Going Down scene involving Kaji kissing Misato started with this, from the way he's holding her and her protests afterwards (through Kaji doesn't find the latter very convincing).
In Night Walker Cain plants one of these on Shido.
In No Game No Life Zero, When Schwi first meets Riku, she suddenly kisses him in a (failed) attempt to seduce him.
Played for Laughs in One Piece during the cover story Gang Bege's Oh My Family, where the virus-themed Germ Pirates attack the defenseless Dressrosa by spreading the Kiss Kiss Virus, which pushes people infected with it to grab and kiss the closest person they run into regardless of gender or looks. It causes quite a ruckus.
In PandoraHearts chapter 3 Alice does this to Oz. This case is a little different because it's not because she likes him - she reveals later that she doesn't even understand the implications of a kiss; she was only doing it to get her blood into him... somehow.
Momo from Peach Girl has this happen to her by Kairi's brother Ryo. She manages to fight him off, before he can take it further, though. This is also Sae's favorite seduction tactic.
Used twice in Penguindrum. In episode 9 Sanetoshi fails to give one to the possessed Himari, but the episode after that Masako succeeds into planting another on Himari's brother Kanba.
Phantom Thief Jeanne: Sinbad has grabbed Kaitou Jeanne and kissed her at least twice. The first time, Jeanne was too shocked to do anything, but the second time she immediately shoved him away (then wondered where he went; maybe a rooftop wasn't the best place for that).

In Rave Master, Lucia does this to Elie, causing her to cry and enraging Haru to the point of wanting to kill him.
Romeo gives Juliet one in Romeo × Juliet. Complete with romantic bridge setting and fireworks. Less romantic is when Ophelia gives her one in the penultimate episode.
Prince Diamond attempts to do this to Usagi twice. He only sees her as her future self Neo Queen Serenity, whom he has an insatiable lust for. Needless to say this is an I Have You Now, My Pretty situation and his attention is very unwanted. Usagi didn't even feel sorry for him until he was dying.
In the manga and Crystal, he does kiss her, only once. Usagi makes it clear she isn't into him and is deeply upset that he kissed her. She even wipes her mouth off. Not only is it an I Have You Now, My Pretty case, it's also a case of Attempted Rape and it's not just any type of rape, it's statutory rape as Usagi is 14 even with Japan's official age of consent; Takeuchi clearly intended the kiss to be sexual assault. In these versions, Diamond is a completely psychotic villain who is rightly killed for murdering millions of innocent people, including a child directly at his hands (manga only due to there being strict rules about what is shown on TV), and seeing the heroine as an object for him to own and control. Nobody sheds any tears for his death. Takeuchi's message was clear: these types of guys are worthless douchebags who will abuse you and no girl deserves a guy like that.
Takano forcefully kissed Onodera... only to show a mangaka how a kissing scene should look like. They are shoujo manga editors.
He later does it again, but this time, trying to get Ritsu to remember him and their past relationship. Needless to say, Ritsu isn't okay with another kiss being forced on him by his boss.

Famous Idol Singer Utau Hoshina forcefully kisses the mysterious cat-boy Ikuto Tsukuyomi, much to the shock and horror of Amu, Kukai and their Charas (to quote Ran, "It's an adult's world!"). And it becomes Squick once you realize how they are related: she's his sister.
And Ikuto himself is so displeased that he slaps her away.
In chapter 145 of Skip Beat! Sho does this to Kyouko.
In Strawberry Panic! Yaya does this to Hikari at the end of episode 13. In the following episode when we see the scene again Hikari shoves Yaya to the floor when Yaya starts to grope her. An understandable reaction seeing as how Kaname had just tried to rape her before that.
In Taboo-Tattoo, the Big Bad princess does this to the heavily exhausted and defenseless main character in chapter 9.
