A grin appears on Stella's features when Ari shivers underneath her touches. The soft sound he let's loose is music to her ears.  She makes him work to keep her lip locked, breaking away here and there only to be recaught with a bit more energy from him the next time around. Glancing down at his manhood, she decided to drive him crazy. Keeping her arms wrapped around him for stability, cloth still hand, she rubs against him, listening for another sound. She can feel him becoming hard. Since she didn't get to explore and learn how to please him as well as he pleases her, she's certainly going to do so now. She keeps one arm wrapped around him, keeping him close, while her other appendage she moves to gentle rest his member in the palm of her hand. With her thumb, she makes gentle circles, smiling at the almost instant groan that he lets loose.
