Her dangling earrings.
He is mesmerized, like a moth to flame when he sees the perfect beautiful earlobes of hers dangling with new colors every day. He thinks that one day would come, when he wouldn't be absolutely amorous, watching the jewelry on her in unbelievable ways. But he finds himself being wrong with each passing day. He cannot get enough of kissing the pendulous part, soft like silk, each night, each day, each moment that he can, and savors the moans he elicits in response.
