My wife knows about my titfighting and sexfighting fetish, and has even indulged me once or twice in the past.
But one thing shes been doing lately is narrating fights to me. She'll ride me and abuse her tits, while telling me a story about her being defeated and flattened. Usually culminates in her flattening her own tits and "surrendering" to her opponent.
Anyone partners here do that for each other? Its worth a try!
