He shouldn’t have imagined her lying naked on his bed. She shouldn’t have imagined his devilishly handsome face between her legs. But it was too late. Kiara began noticing Ethan's washboard abs when he hopped out of the pool, dripping wet after swim practice. Ethan began gazing at Kiara’s golden skin in a bikini as a grown woman instead of the girl next door he grew up with. That kiss should have never happened. It was just one moment in a lifetime of moments, but they both felt its power. They knew the thrumming in their veins and desperation in their bodies might give them all they ever wanted or ruin everything if they followed it. Kiara and Ethan knew they should have never kissed. But it's too late to take that choice back, so they have a new one to make. Fall for each other and risk their friendship or try to forget one little kiss that might change everything. PREVIEW: “If you don’t want to kiss me then... let’s swim.” “Yeah, sure.” “Naked.” “What?” “I always wanted to try skinny dipping. And I really want to get out of these clothes.” “What if someone catches you... me, both?” “We will be in the pool, Ethan. And no one can see us from the living room.” I smirked when I said, “Unless you want to watch me while I swim, you can stay here.” His eyes darkened, and he looked away, probably thinking the same when I noticed red blush creeping up his neck and making his ears and cheeks flush. Cute. “Come on, Ethan. Don’t be a chicken...” “Fine.” His voice was rough when he said, “Remove that sweater first.”
