I'd imagine it'd feel like fucking a wet plastic bag with her constantly rinsing her pissy juices off your dick.
Anyone who's ever actually had sex in the shower would know that water somehow makes it dryer. It's not a very good lubricant.This probably isn't very pleasurable
How the fuck? Any time i have ever tried shower sex(the exact same way as the gif) her pussy clammed up and nearly torn my dick off, and she couldnt have sex for a day or so from the rawness.
