Write a 1200 word story about Ahri and Sona from League of Legends. Ahri, Sona, and I are roommates.  Ahri and Sona dared each other to model bikinis in front of me. Ahri and Sona were very curvy women with the biggest breasts I had ever seen, so I was eager to help them. Ahri wore a tiny thong bikini and Sona wore a sling bikini a few sizes to small. Sona turned around and shook her butt, the best part of her sling bikini was that the back strap went right between her butt cheeks. Ahri saw the way I was looking at Sona butt, and she was not one to be outdone. Ahri stood next to Sona and pulled the back of her thong bikini up between her butt cheeks as much as she could. It was getting harder and harder to hide my growing erection. Ahri and Sona were bold, they did everything they could to show off their butts, they were practically twerking in front of me.
