A grave mistake

After that night, you two had sex every day. As Aoife said: "No matter how much you shoot inside me, I can't be more pregnant. Why don't we enjoy this chance?"

One month later, Aoife told you: "Your new teacher will arrive by tonight, so let's hold a parting party. I'll go to the river to catch some fish. Can you go to the forest and get us some meat?"

After three years of training, you had become a good hunter. In the morning, you got a dozen rabbits, five birds, and a boar. Return to the hut, you saw that Aoife hasn't come back, so you went to the river to look for her.

You found your teacher soaking in the river. She fell asleep while taking a bath.

An idea flashed through your mind. You quietly came near her, undressed and hugged her from behind.

She woke up when your penis entered her.

"Before I leave, let have fun for one last time."

She didn't respond with a passionate kiss as usual. Look like she was still sleepy, but you didn't mind to do all the hard work. You moved your hip faster and faster, your cock continuously moved in and out her vulva. However, when you felt her pussy tighten around your swollen penis and was about to cum, a familiar voice interrupted:

"Hm, what an interesting scene."

Raising your head, you saw another Aoife stood on the bank and looking at you with a smile.

Your mouth opened widely, enough to put an egg in: "Then who is..."

The woman who you were mating with answered: "I'm Scathach Spiker, a general of the Piena Kingdom."

Aoife added: "My older twin sister, also your new teacher."

You were confused. Your consciousness told you that you should pull out, but your instinct insisted on continuing.

Aoife didn't help but add fuel to the fire: "I'll tell you a secret: we have the same menstrual cycle, so I'm pretty sure she's ovulating today."

At that moment, Scathach began to move her hips and talked: "Don't pull out. Come inside me."

Her cervix touched the tip of your cock and sucked it in, that made you reached climax. Your cock shot a big load into her womb.

Scathach moaned in orgasm: "AAHHH!!!" then fainted.
