My sister got drunk and, in a hazy state of mind, suddenly slipped into my futon. Surprised and flustered by this sudden turn of events, my body reacted instantly, my cock growing harder by the second. My sister, who secretly gets off on seeing me in my underwear or catching glimpses of me changing, stares at me with intense desire. Feeling her burning gaze, I struggle to suppress my inappropriate urges, yet grow even more aroused. Overcome with heat and longing for her brother's cock, she quietly sneaks into the room. She kisses her sleeping brother's face, their lips meeting in a deep, passionate embrace. Then, she gives him a relentless, fiery blowjob, sucking him off until every last drop of cum is completely drained from his cock.
