My super Ke'ai stepsister Ichika teases me by showing me that she's not wearing any underwear while we're eating. One day, my wife goes on a company trip for the night. That night, the devilish Ichika shows her true colors, suddenly giving me a blowjob while I'm sleeping in bed, and continuing to lick me even though she's on the phone with my wife. Her Ke'ai expression makes me lose my sense of reason, and I end up having intense sex with my stepsister all night long. In the morning, I wake up to a cute kiss, and she's so Ke'ai that my carnal desire won't stop, and I end up cumming inside her while feeling guilty!!
