Ikkitousen's first episode featured a scene (picrel) where the psychosexual Ryomou literally gets an orgasm from breaking a dude's arm. The anatomy in each of the shots, the sequencing of the grappling, the vocal performance of the seiyū fluctuating between hostile sadist and succumbing to her own ecstasy is just perfect. I don't know if I can link that first episode here without breaking the board's rules.

What's the hottest thing anyone here has seen in an ecchi anime?

(Yes, I will be posting a few extra images so this isn't just an /r/ thread. /r/ doesn't "get" ecchi which is why I'm posting here.).
