For a few weeks there was a feeling of awkwardness between us and we didn't look each other in the eye. But today it all happened again. My stepsister was going out with friends and was talking to her stepparents. Suddenly her gaze met my belly button and she seemed to freeze. My stepsister grabbed my hand and dragged me up to the room. A little unexpectedly, but I didn't mind. She immediately began to lick my belly button and caress it with her long nails. Everything was like a dream, her tits touched my cock, she sucked it sweetly. And then, her gentle hand began to tug my cock, and her other hand fucked my belly button. When my sperm flooded the belly button, she again brought her finger to her mouth and ran away. Wow, I love my stepsister.
