Thinking about... A young Ephraim and Eirika coming of the age of puberty. They become curious about the differences in each other's bodies. They've seen each other naked before, but before now they didn't pay much attention to it.Ephraim is braver, touching Eirika, and she lets him nervously. Her breasts have started to grow. Right now they are tiny, sensitive mounds. She sqeauls when he squishes them.
They look at each other's genitals, notice how different they are. Opening Eirika's labia with his hands, Ephraim figures out one goes into the other. He feels enticed, entranced by the small pink hole. It's tricky to get inside though, still so small himself. It hurts Eirika at first, but she gets used to the shallow filling.
Not really being aware of sex, they just stay close to each other while connected, sometimes thrusting by insticnt, but otherwise laying still, enjoying the warmth. Ephraim cums eventually, neither knowing the risk of doing so (nothing actually comes of it though). As he always has, he rubs Eirika's face to make her feel more comfortable.
I also imagine a scenario where their father Fado finds them, but doesn't enter the room. He is unsure what to do about his children being this curious, and worried interrupting them might traumatize them. Perhaps it's time to have the talk after all, but how would that make them feel, after doing this? A vexing situation.
