Aphrodite narrowed her eyes, but allowed Peitho to turn her head anyway. However, she was the one to lean in, taking ownership of this kiss.
Really and honestly, Peitho was the one who should be taking the lead here. This encounter was all about lust, about sex, and that was legitimately Peitho's realm. Aphrodite might have been the goddess of desire, but she was also the goddess of love... and there was none of that here.
However, Aphrodite had one key advantage here: she was one of the Twelve Olympians. Her pride in her position in the pantheon, and just as a celestial being, would not let her kowtow to Peitho, no matter how much she technically should.
She pressed Peitho against the door of the car, kissing her firmly, but not quite roughly (Aphrodite had far too much class and grace to be rough this early in the piece. They were still in the cab, for pity's sake). Her hand slid up Peitho's side, leaving no doubt that she intended to control things, for now at least.
Perhaps she might let Peitho take her turn at some point. It had been some since Aphrodite had been... dominated, in a satisfactory manner. The paltry attempts of her last lover, a mortal male, did not count: Aphrodite had been barely stifling her laughter the whole time he had been attempting to dominate the goddess of love.
