Would you rather get a blowjob from a mermaid, i.e. human upper body and fish lower body, or sex with a reverse mermaid, i.e. fish upper body and human lower body.
For the sake of comparison, they will be the best blowjob/pussy you'll ever get, the human half will be beautiful to your standards, you can cum anywhere you want, the encounter is consensual, and she has the personality that suits you best.
Human upper half. I'm a boob guy, having a nice set of firm juicy tits is important to me. Also, the human upper half means that I don't just get blowjobs, but also handjobs and titjobs

Mermaid because 1. a fish top half would be disgusting and 2. good head is always better than good pussy
