To him, it meant nothing. The passing of their lips, his body on the other's, the sound of moans in the background.
It was just an experiment. Nothing more.
So one night, he confronted him about it, the sitarist pinning him on the bed, everything was hot and sticky. Looking up, he said…
"You know this means nothing, right?" And it wasn't a question.
Demyx gave him a sly smile and answered. "Of course. Nothing at all. What else would it be, Zexion?"
Zexion pushed him self up with his elbows and brought his self closer to Demyx's shoulder, because a scientist must always make sure their subject never gets out of hand.
"Nothing at all." And he proceeded to bite down on the other's shoulder and let the moans drown out anything else.
Because it was just an experiment, that's all.
