Making a deal with Frieren

This Grimoire is the one she needs and this little elf Frieren is not going to leave without obtaining it. She has no idea what it will cost her but as she stated, "I will do anything for it". I guess in the end the shop keeper took her at her word as he lay her down and spread her lovely elf ass cheeks and mounted her pussy from behind. He was not done yet after he came in her he turned her over and slid his cock in her again to get as much out of her as he could.
