FNS-140 · I Lost to Her Sister's Temptation: Pantyless, Anal Cunnilingus, and a Plump Ass

the first time i went to her house, the one who greeted me was her little sister, momo-chan, with a slightly cheeky and devilish smile. she comes to bother me as if to interrupt my time with her. at night, when i came back from the toilet, i glanced into momo-chan's room, which was suddenly open... to my surprise, she was lying down without panties! i stumbled in a panic → momo-chan, who noticed the noise, glanced over here and smirked. "you were watching, weren't you? ...it's sex, after all," she said, thrusting out her plump ass and tempting me. "you're staring so much... do you like asses? ...you can lick it, you know?" from that moment on, a secret relationship between me and momo-chan began, hidden from her. at first, it was just a whim, but before i knew it, i was captivated by anal. my reason collapsed, dominated by that pantyless ass. i can't live without momo-chan's anus pheromones anymore...!
