The idea of her receiving pleasure in secrecy with someone else is actually quite a sexual turn on for me, even if the emotional consequences would swiftly end that, should fantasy become reality. Pretending that she just can't resist due to how hot and bothered she gets around the guy (me), allowing herself to indulge in those lustful cravings, never fails to excite me.
Likewise, imagining her going down on another woman is quite arousing. I haven't ever thought to consider my penis as a clit, or the 'other woman' as myself, but after hearing this, I may just give it a try in the future. During my previous relationship, we sometimes pretended that she was sliding herself into me (replacing the prostate massager), which always led to an explosive orgasm on my part.
Depraved fantasies are some of the best.
