DVRT-6803 - My sister-in-law, who came to stay overnight, is teasing my sensitive nipples! Mutual nipple licking led to a strong erection, and I'm enjoying NTR while nibbling on a large penis and ejaculating inside!! Shizuku

My wife's sister came to stay at our house overnight. Recently, I've been experiencing sexlessness and was thinking it might be harder to masturbate because of the buildup, but my sister-in-law suddenly started playing with my nipples. She said, "Oh, do men also feel sensations in their nipples?" While she was saying that, she was actually flicking and licking my sensitive nipples, and my erection reached its maximum. Unable to resist with my wife there, I started mutual nipple play with my sister-in-law, and now it's unstoppable! ※ This work shares some content with DVRT-068, scheduled for release around January 2026.
