"R-right..." Eiric nodded slightly, slowly getting up and watching her bend over. He licked his lips as her skirt rode up, slowly revealing more of her until he finally saw it, her beautiful pussy. "Oh my...." He stared for a few moments, then slowly moved around to walk behind her, though he had to stand over 4 feet away to give enough room, leaving him halfway across the living room with the tip of his cock nudging against her. "Ok...here I go sis...I'm gonna take it slowly ok? Just say when you want me to stop" He hesitated for a moment, then gently pressed the tip of his cock against her lower lips. He shivered and groaned, then with a bit of resistance, the large head of his cock slipped inside of his twin sisters body.
