Nestled deep in your lair is an enchanted hot spring. Though deep underground, the spring appears as a serene, snowy mountain bathed in an eternal sunrise. It is here that you bring your big boobie elf slaves to birth your many offspring. You wade through the warm waters, rubbing and caressing their swollen flesh. The enchanted spring soothes the girls' labors and acts as an aphrodisiac. Their big bellies swell and bounce as your spawn wriggle within them. They look up at you as you pass, hopeful for attention, each girl fondly remembering your touch that got them pregnant in the first place. The spring is a chorus of moans and gasps. Some of the girls are already close to birth, others haven't even started labor. You brought a flock of your Harpy minions to act as midwives and ensure the health and safety of your precious busty elf slaves while you attend your lustful desires.
