Not sure if this exists but how about simple kissing/embracing animations? All day every day straight to business and rape.
there is a lie down and kiss animation in the deadra sutra standard animations file, It's number 21., there's also a hug mod uploaded to nexus by ishiitakeru
May I suggest animations that work well for double ended didoes? or just trebidism in general. I know there's one animation around here as well as # 99 from daedra sutra.
.... although, it would be nice to have a bit more tenderness in this game, maybe you should add to the short list of animations that are out there.
