Navi knew about sex from what she'd read online; she knew what organs went where, and even roughly why orgasms occured. She just had very little idea as to what brought them about. Alec was starting to give her ideas.
His kiss sent bolts of electricity down her body, making her knees shake a little. She clung to him for stability, and partly because she wanted to feel his skin against her own. It was almost too much for her to handle, the sensations moving too fast in her head, like butterflies just eluding her grasp. Instead of trying to process all the information as it arrived, she tried coasting on it, and just picking up whatever bits she could hold onto, how Alec tasted as dark and delicious as he looked, how his hands moving lower down her arms made her shiver and melt at the same time.
She took one of his hands and placed it on her breasts lightly, breaking the kiss to look up at him. "Just with you," she murmured, her promise implicit. She wouldn't fly away from him when they were done. She had his word now.
