As the search for a spell to give one of them a member continues, these two mares are left to please each other in a plethora of new and exotic ways. Conventional alternatives to vaginal sex just weren’t doing it for Lyra. Bon Bon lacked the equipment for proper love-making, but Lyra still wanted to feel her inside her most intimate area. Then, it dawned on her. Bon Bon was apprehensive. She’d never heard or thought of such a thing, but she was open minded. Lyra laid on her back and spread her legs. Bon Bon first gave a few gentle strokes of the tongue, and Lyra’s lower-lips flared and dripped, welcoming what was to come. Bon Bon slowly inserted the tips of her front hooves, and slipped them deeper as Lyra uttered a long, sultry sighed in tandem with her motion. With her legs fully extended into Lyra’s slit, Bon Bon tucked her head between them and gently pushed her snout through Lyra’s lips. Lyra shuddered, her lower body jerked up as she wrapped her hooves around Bon Bon, and pulled her further inside. Lyra began to pant heavily, as her belly began to swell with Bon Bon’s form. Her body got warmer and she began to sweat. Lyra’s vulva dripped as Bon Bon’s torso slid further into her womb, all the while her belly grew bigger and bigger. Lyra’s pleasure was building, well on her way to a glorious climax. Bon Bon was in all the way to her hips by now, as Lyra could wait no longer. She sprung forward, her front legs collapsing with her rear to the air, and Bon Bon slipped straight down into Lyra’s womb. She gasped as she finally came, and her belly filled with her lover, swelling up big, round, and bulging. Her back legs turned to jelly as her body slumped forward, resting upon her big, bulging belly, and she sighed. Bon Bon quietly moved around in Lyra’s womb, getting comfy in the soft warmth of her lover’s belly. Lyra rolled onto her back, and admired the bulge of her mate inside her uterus, stroking her, feeling her form through the walls of her womb. Lyra laid her head back and closed her eyes, as she continued to wrap her hooves around her belly, and whispered, “Let’s do this again…”.
