One of many that can turn me on is the thought of a young person performing on the piano in the nude.
It would suit a music student. There are great similarities between classical music and sex. Both can be very sensual, gradually build to a climax and after orgasm gradually subside back to a state of calmness. The performer would express the music through his or her bodily reactions and would ultimately return back to the starting point. The pianist would have a partner sitting alongside them, a partner of the opposite gender; their job would be to fully express the music's ebb and flow through their bodily movements, A pianist like Yuja Wang constantly moves with her music, her bottom moving with the sound, sometimes even lifting off the seat without inhibition. It would be her partner's primary function to help her sexual reaction to her music - his bare thigh pressing against hers, when her hand is free, facilitating contact with the eve-increasing size of what is protruding between his legs. As the music moves to its climax their organs do so as well , judging their timing with the music's own flow. The crash of the dissonant , climactic chords would be their cue to take their bow, facing the audience and let them clearly see as well as hear the crucial moment of climax. Boy and girl would take their bows without shame ; rather with a sense of achievement and liberation.
