Two actual erotic dreams I had (that stand out due to LGBT themes and how arousing I found them):

-I was in a hotel room with an ex-gf, I didn't touch her or anything, we were waiting for two men she knew but I didn't, and for some reason when they arrived I didn't get a good look at them. Next thing I know, me and my ex were naked, on all fours, side by side in identical positions. She was already being fucked by one of the men, a blond (me and my ex are Hispanic) and very muscular guy fucking her ass , she squealed while she was being fucked. I knew I was going to be fucked too, I tried to at least take a look at the man who was going to fuck me, I managed to see he was a very muscular black guy, broad-shouldered, and then I felt his huge cock
enter my ass, and soon I was squealing like my ex. I could hear the men chatting, I couldn't catch what they were saying but the tone was very casual, they weren't panting despite how hard they were fucking us.

-I dreamed I woke up in a woman's body (slim, dark-skinned Latina), surrounded by several men who explained it was like a medical experiment, and after some hesitation they said I was pregnant, I just asked how far and they said it was like I'd just gotten pregnant. A man (light-skinned, muscular, clean-shaven) was assigned to act like my husband for my new identity, it had to be kept secret that I wasn't a woman before. We moved to another city and he went out to work while I stayed as a housewife and cooked for him and so forth. I learned about makeup and dressing like a woman (I always chose to wear dresses). One day, when the pregnancy was just starting to show (physically and also in that I was very emotional due to hormones), he casually mentioned that sex was part of our roles, I nodded (I wanted it but I was very nervous), I sat on the bed, I was wearing a yellow summer dress, I took off my shoes (black, low heels) and glanced at my (smooth, shapely) legs, I told myself I had nice legs, and smiled at the irony that even though I was pregnant I was really a virgin as a woman, and was about to start undressing (my plan being to strip, lay on my back and spread my legs for my husband and let him take over) when I woke up.
