Tantra which is an ancient yoga gives a couple 18 hour orgasm

According to Melanie and Scott McClure they claim that love-making to breathing, dancing, and the weather condition can cause them to orgasm. They proved this by sharing a video where their bodies were quaking intensely from an orgasm which resulted from them hugging. They say they can even orgasm without touching at all and one of them can reach orgasm simply by watching the other orgasm. They even sometimes have orgasms with friends. 
“Melanie and I can even have orgasms with friends we’ve never had sex with but whom we practice Tantra with. A few months ago, we went camping with two friends and we were all having orgasms from the lightning bolts outside," Scott said.
