Honesty is probably the best policy in this case. You have learned so far that this town seems to have a such a strange obsession about preventing kids from learning about sex that it even wants you to keep information to a minimum as you are giving them sexual punishments, but it's probably safe enough with someone who has been caught more or less having sex already. It might even serve to complete her education a little. You can probably find a few things you can tell her easily enough without overstepping on anything this town would get mad about.
You take your finger out of her vagina and try your best to put on a persona of a doctor who just finished a medical examination. Having just had your penis pressed up against her entrance a moment ago, it's almost torture trying to back off from the urge to immediately fill her with your semen. However, you would much rather her be as happy as possible when you actually do it, so it's probably a good idea to back off for at least a moment.
"Well, it doesn't look like the bleeding is anything to actually worry about." You tell her. "It looks like he just partially broke your virginity. You would have to break it anyway if you want to have a boy make a baby with you, so you were going to have to do that anyway."
"My virginity!? What's that!?" Melany asks as she tries to curl up into a super tight ball in order to look at her own spread-open vagina.
Great. Well, considering this town, there's only one way you can actually approach this topic, and it's going to make it difficult to explain this correctly.
"You know about the virgin Mary and all that, right?" You ask her. "Your virginity is something inside your privates where Marcus' finger was. When it's broken, that means you're not a virgin anymore." You decide not to tell her about the fact this town also calls it your 'purity' though. With all this town's messaging, that would only make her scared.
"It is supposed to be broken by a boy sticking his penis inside, not a finger, but after it's broken then you can try to make a baby with him."
"Really!?" Melany looks up at you, suddenly brightening up just a bit. "Wait, so you mean sticking a boy's privates inside my private parts really does make me have a baby?"
She sounds like she's interested. Well then, securing her willing consent should just take one more push now. How should you approach the matter exactly, though?
