Maud Pie is a strong mare, but not strong enough to overcome her own biology when her overwhelmingly strong earth pony heat hits on a visit to her family farm.

Igneous Rock is a strong stallion, too, but what stallion could resist the scent of a mare in heat, or the mare herself just begging for a foal, and offering herself up to him?

Even if she's his own daughter?

Can Igneous resist the urge to mount his daughter and breed her like the mare in heat she is, or will instinct win once more? Hell yeah it will!
