Fenrak was feeling hard pressed to avoid making small sounds of pleasure, yelps mostly. As she let out her pleas for more it was too much for him, she was very comely indeed, and her willingness combined with the bouncing movement, the sheer<em>tightness</em>of it all was creeping into his thrusts. He lingered at the end more, he leaned further into each little movement, and most of all, he started yelping a tiny bit every time the massive head of his cock would embed itself in his womb, and he would have to free it by yanking back hard, making that wet popping noise as the knot exited her nether lips. He growled and every thrust was more brutal and jerky, he felt it building in his member, the begging for sweet release into his new, not-so-fragile breeding tool. He let out a bark and his cock swelled beyond it's already ludicrous proportions, actually stretching his womb when he pulled out and slammed in as hard as his large and wiry muscles would allow. He felt intense pleasure at his first truly pleasurable cum, more than the last time being let out. Her stomach bulged strangely as the swollen cock blocked all release, the gallons of cum jetting into her stuffed womb. He pulled out and panted, thrusting one more time for good measure, letting a massive strand flash onto her breasts and face as he pulled the knot free. She was well and truly filled with cum, sure to be pregnant. "It will only be minutes before my demonic seed burrows into your all too fertile womb, an hour before your stomach swells in the final stages of pregnancy, and a few more to actually release my clutch, I think you'll enjoy their swarming when they release, maybe they'll even have their way with you, as they feed from you." He laughed one more time. "I'll see you in four hours, to give you your next litter." He bounded off, intent on the village, even as Sigyn would feel just the sensation he described, the sperm aggressively fighting their way into the walls of her womb, a strange and unpleasant sensation.
