I have always wanted to be with a pregnant woman. For me it is both a bucket list but also an idea that her hormones have just jumped to the next level and I'm about to get used in ways that will make me want to tap out.
The other is a long wet and aggressive stripper slide. There is nothing better than a woman with large lips wrapping them around my cock and using me to get her clit off as she slides back and forth until we both have an O.
Just my two cents.
