"...a baby?"
"Yes, in about six months. This is your first time, I presume?"
"Yes, I've never... But mom only lets the doggies use me. She says I'm too small for it anyway."
"It can only take one intercourse for the pregnancy to happen. How about some teacher at school? Or a neighbor? That had to happen at least once in the past three months."
"Oh, I mean, yeah, but... Everyone knows my pussy is for doggies, and dad makes sure my ass is well lubed every day. And I have the tattoo..."
"'Anal free use only', yes, but are you sure everyone has listened to it? There had to be someone, since you're pregnant now."
"But they know my dad! They know he wouldn't like it."
"Hmm, alright, what about your brothers, then? Or your dad?"
"Well, dad sometimes uses my pussy too, if the doggy doesn't take long enough, and he says I should have some more dick. But that's dad, right? That's different."
"Oh, sweetie, your dad can absolutely get you pregnant."
"What? Wait, really?"
"Yes, though we could run a test later, in case it was one of your brothers or someone else entirely. We should go get your dad here, though. If he decides to keep it, you will have to have much more penetrative sex than before. You're still far too tight to safely give birth at your age. A bigger dog would be helpful, or I could suggest some toys for him to use on you."
