My best friend's girlfriend, Nanachan, has an incredibly cute smile. While visiting my best friend's place during a business trip, I got to see her again—she's been living with him. I've secretly loved her for years but could never confess because she was off-limits. When my friend was away, I discovered she felt the same way. She grabbed my hand, confessed, "We should've been together," and whispered, "Let's forget everything just for now. Come to bed." Resistance crumbled. I indulged in her fair-skinned, sensitive body, our tongues intertwining as I pounded her shaved pussy hard from behind, losing control completely while my best friend was away. We made a pact to keep it secret, and I even gave her a cleanup blowjob—this is the story of a forbidden, burning night.
