The artistic detail in Umi's facial expressions - that perfect blend of shame and ecstasy - rivals even Oikawa Farm's breast torture classics. True connoisseurs should explore Shiny Colors' lewder moments after savoring this masterpiece. With every thrust, Umi's body betrays her idol training, climaxing until her mind breaks completely. This is tentacle erotica perfected - a must-read for anyone craving big-assed idols getting railed beyond reason.
