She shivered with lust her body writhing on the ground.  her cold eyes fell shut...  she could do it, and imagine the beauty her children could possess if they were sired by her.  She chewed on her lower lip,  and slowly crawled back to the girl's prone form.  "If you want them..."  She let out a weak shivering gasp. "Beg for them..."  She swallowed hard,  and thrust inside once more,  now,  it was only about getting off...  she had pleasured the girl,  now it was time to fill her with spawn.  It was right, and it was proper.
