In case anyone is curious, here is what the "Big Skin Cream Love Hotel" turned out to be. The story may be a little disappointing compared to how weird/exotic/mysterious it sounded, but maybe it is of some interest and will give some impression of Japanese love hotel experiences.
Love hotel rooms often have very large "ofuro(s)", a big room for bathing with a big and deep tub for two (or more) and a very large shower area in which you soap up and wash off thoroughly before getting into the tub (the standard procedure for a bath in Japan). In a love hotel this more-or-less standard ofuro set-up will often be enhanced with various additions to set a romantic/erotic mood or for sex play. An inflatable rubber mat and a supply of oil for playing a soapland-style slip and slide game is common, as is a TV screen for watching porn or whatever, an audio system for mood music, adjustable romantic or stroboscopic lighting, jacuzzi jets in the bath and so on and so forth.
Anyway, this whole "Big Skin Cream" deal (my Japanese lady friend's name for it, btw...don't know what the hotel itself called it in Japanese) was a theme for a room in this particular love hotel. Namely it was extensively decorated with plastic replicas of erect cocks...just poking out of the wall at random, in the closet alcove to hang your clothes, handles on the faucets, an enormous one poking out of the headboard over the bed (by enormous, I mean about a meter long and maybe 8 inches in diameter) and so on. Maybe you get the idea...a phallic room theme. I had never seen one like it before, but the basic idea fits pretty well into the (enormous) range of love hotel room themes you can easily find. Nothing particularly remarkable so far.
The skin cream, or lotion, part was that in the ofuro shower area there was a whole row of these plastic erections set up to dispense various liquids by jerking them up and down with an HJ like motion. Depending on which one you used you could get liquid soap, shampoo, conditioner, toothpaste (!), lube, a couple of erotic oils (the kind that make your skin tingle/warm) and actual skin lotions. All these were labled in Japanese...so I depended on my friend to keep me from brushing my teeth with shampoo etc. Finally, there was a little ledge at the end of the row where a guy can sort of half lean and half sit to have his own cock join the line of plastic ones...for the "use" of his date. You can perhaps imagine the sort of silly and simple but charming little games and pretends to be played with these...such as the lady getting "ejaculated" shampoo into her hair.
My date for the evening, with her usual playful enthusiasm, found all of this hugely and endlessly hilarious and fascinating. I think she could have entertained herself all night. And, while I wasn't as blown away and felt somehow disappointed because I expected something more exotic/amazing (don't ask me what...no real idea), I had quite a good time too. Her playfulness is contagious. The best part was when she gave me a BJ as I sat on the little ledge, took a "pearl necklace" and then rubbed my cum onto her chest.
One more detail: my partner was riding me cowgirl style in the bed, and at one point she reached up and around the giant model of an erect cock poking out of the wall and used it to pull herself up and push herself down in addition to pumping up and down with her thighs. It was a pretty weird view from my perspective looking up at her and it. I later realized that if we had oiled up her body and turned on the strobes for illumination, the whole scene would have been like something out of an erotic acid trip.
Finally, I think she called it "skin cream" because she knows (don't think she learned it to me) that "creaming" can mean ejaculating...in fact she often calls it that.
