To make the scene feel real, focus on more than just the action.
Lingering eye contact or a hand that stays on an arm just a second too long.
The most compelling scenes usually start long before the physical contact. In this specific genre, the tension often comes from a shared history, a "forbidden" element, or a sudden realization of mutual attraction.
Gentle, exploring kisses that test the waters.
Focus on urgency, heavy breathing, and more assertive body language.
