I love nuru massages, but the stuff is water based, so after it cools off, it leaves you shivering as it evaporates off your body.

 
But one beastly hot and humid day, me and a friend did a nuru massage on an outside deck, putting down an air mattress covered with towels,   When the nuru evaporated it left us feeling cool and comfortable and we really got into things.

 
It was one of my all-time great sessions.

Ages back I had a date where she focused on oral temp play. Sometimes should would have an ice cube or ice cream when she provided oral. Sometimes she will fill her mouth with warm tea. Alternating sensations without knowing which was coming was exciting.
