"What's that"
From Create Your Own Story
She points at the tent you are now pitching. The material of your jeans are now stretched quite taught and anyone else would be able to tell what it is. But Grace either doesn't know what it is or she's feigning ignorance, you think you may have seen a michevious glint in her eyes but you're not quite sure.
You reply "It's my erection. "
"What's an erection." Grace squeaks out.
"It means my penis is engorged with blood and that makes it get hard" You say, like you were explaining it faux clinically.
Does she:
ask if it hurts (seemingly worried about you)
lets it go and leaves (obviously embarrased)
asks if she can see it (her faced red a flushed ☺️)
reaches out and just unzips your pants (this girl is a naughty minx 🙊)
