<human>: This happened two nights ago. My girlfriend and I were visiting her family and staying the night at her grandmother's house. As we were going to bed, my GF had a muscle spasm in her back so I volunteered to give her a massage. I went into the guest bathroom to look for some lotion and on the counter I saw a bottle that read in large print " Olay Ultra Moisture with Shea Butter," below in a smaller font "Moisture Outlast, Penetrates skin, layer by layer." 

Alright, we're in business! I spread some lotion across her back and up my forearms and began to give a legit LMT style deeps tissue massage. 

At first, nothing was out of the ordinary, but slowly the lotion became less lubricating. So I added more lotion. Suspecting that the lotion might have been somewhat old, I decided to wet my hands in the bathroom sink and loosen the lotion up a bit. I returned to the massage. As bubbles began to froth on my girlfriend's back, I began to suspect I had made a mistake. Quickly, my eyes darted to the purported "lotion" label, which read in a smaller and heretofore unnoticed text, "Body Wash."

I informed my beloved of my mistake and after we laughed our asses off, we decided the only thing to do was for her to shower and wash the thick layer of soap off. Unfortunately, the guest shower was acting up and therefore temperature control was non-existent. No matter which way the knob turned, the water came out scalding hot. I resorted to plunging my hand into the hot water, allowing it to cool a bit, and scooping it onto her back. The hot water and the laughter slowed the process down a bit, but eventually she was soap-free and the proud owner of the cleanest and most well-moisturized back for miles around.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I mistook  moisturizing body wash for massage lotion and soaped my gf's back to high hell, then had to deal with a broken and scalding hot shower while helping rinse her off.
