Frisk felt Sans almost pull out, the fill her full again, there was no denying that she loved the feeling. Every vain, and pules she felt touching every part of her. He felt perfect, fitting her very well. She kept pushing back against him, even when he started to thrust harder into her. Though after awhile he was moving to fast, she couldn't keep up. So she just let him have her, laying there while he please her and himself. Her eyes half lidded, she wanted to close them, but the look on his face was just full of pleasure and lust as he dove in and out of her. She welcomed his finger in her mouth, closing her lips around it she started sucking and rolling her tongue around it. Moaning onto his finger, she couldn't hold back any longer, his first load filling her was just what she needed, it was so hot inside her. Her pussy tighten around his cock, milking every bit of cum he spilled in her. Her eyes rolled back in her head, her body shivered with her third orgasm. Each one was better than the last, this was all she dreamed of, but better. He gave a few hard thrusts, making her yelp a little. Not from pain, just by the force of them. Once he was done, she felt his face on her back, and felt the warmth of his cum dripping down her inner thighs. Her first though once her mind was clear enough was that they didn't use a condom or any protection. She panicked for a moment before she remember that monsters and humans can reproduce like this. She sighed and smiled, enjoying the moment again. "Thank you..." She laughed. She thought about his offer, she wasn't done yet. "I sure I can keep going~ What about you? Any fantasy's about me you want to try. This is our night~" She purred to him, wiggling her hips a little at him.
