And often at the end, too

... and I've showered with many providers after a session, when the session involved massage and both of us were slick with oil or lotion or nuru gel or... whatever. We both had to clean up anyway, and this way we could scrub each others' backs... and other body parts. 
On a related subject, recently I suggested at the start of a longer session (which would include massage) that we reserve the last 30 minutes or so for a relaxing bubble bath. The provider thought that was a great idea. But when we adjourned to her bathroom to start the bath, there was no drain stopper to be found. 
Just one more thing to remember to bring with me in the future!
...join her. It can be kind of a bonding thing. I also assisted this young lady with a bubble bath before our session. I sat outside of the tub and made sure the bubbles were appropriately distributed about her lady parts, washed off, reapplied, and on and on.... 
My buns are still glowing from all the wonderful adoration and attention Thank you
It is so natural for me to want to clean up with someone when we're done... a simple 5-10 minute shower where we soap each other up and do some flirtatious rubbing is just the cherry on the cake And I love cherries! If you want to shower first just let me know so I don't get all dressed up to the nines just to get undressed and shower XOXO I actually just made a bubble bath video if you're curious what I might look like covered in bubbles.
Thanks for the shout-out. Yes..I've been known to offer some of my best b2b work in the shower. Just exchange unscented soap for massage oil and let the good times rock & roll.
