Only have experienced this twice in the decade or so I've been getting massages and both were after the session. One of the showers was a bit more playful, with lots of mutual touching, body contact, amd kissing. The other was more like a back / butt scrub, which was still nice. Didn't ask for either, they were just offered and no upsell. My only issue with the latter of the two experiences was the condition of the shower: not as clean as I'd preferred and way too tight to make it comfortable.
