Couples quartet do yoga and then a sexual exchange.

They were a group of friends who always got together to carry out any activity they could think of, the last idea had been a yoga group, they would do it every morning in the hope of improving their health and elasticity, however when the time came they could all notice that there was a strange tension. As if everyone was anticipating something that no one could decide to start. It all started when Elisa's thin blouse slipped off and exposed one of her breasts, and everyone accepted that this tension was a sexual desire that would not be satisfied until everyone was naked.
