IENFH-007 - Teasing my sleeping sister turned into a trap: trapped by her legs and forced to creampie

My sister came home after fighting with her husband, and seeing her sleeping so defenselessly was too much to handle. I tried to tease her, but she turned the tables on me! Even though we're family, she locked me in with her legs and wouldn't let me escape. I couldn't stop myself, and before I knew it, I was forced to finish deep inside her.
