Your Actual Real Fantasy? --> I fantasize about my SO coming home one night having just been fuckd by another guy, who filled her with his come. She only had him 15 minutes or so ago, so she is still hot and aroused from his coming inside her. She takes off her dripping panties and I am rigid already. I slide inside her, her cunt is relaxed from having him inside, and she is wet and slippery from his jism. I feel all their juices running down onto my balls. As I thrust up and down I imagine his dick rubbing the inside walls of her cunt just before, and him thusting against her, as I am now, and I groan and come, filling her up with my cum.
