Write the following as a 1400 word story. Yae Miko and Beidou are staying with Aether in his Serenity Teapot. Beidou walks into Yae's room and sees Yae bent over, her face buried in a pillow with Aether taking her from behind. Beidou could hear Yae moaning into the pillow as her butt jiggled from each of Aether's thrusts. When Aether saw Beidou he pulled out of Yae in surprise, letting Beidou see his enormous hard cock swinging around. Beidou's eye's winded in shock at Aether's size, it far surpassed anything she had ever seen before and she wondered how Yae could even fit that in her pussy. Yae let out a sound of disappointment into her pillow and shook her butt, Beidou watched as Aether quickly obliged and thrust back into her. Beidou walked over and sat next to Yae on the bed, interested in watching this thorough pussy pounding as Yae was fucked silly. After several hours Yae was completely spent and Aether pulled his member out of her, his cum leaking from Yae as he did so.
