極限まで勃起したナリタちゃん（Narita with a maximum erection.） (Pixiv Fanbox)

リクエスト 「今までで一番太く、大きく、長く、太い乳首の勃起を見てショックを受けるナリタちゃん」 外気に触れただけで立てなくなっちゃうんだから このまま手のひらで捏ねたらどうなっちゃうんでしょうねぇ… Request "Narita shocked to see the fattest, biggest, longest, thickest nipple erection she ever had." What will happen to her if her nipples, which are so sensitive that she loses strength in her lower body just by touching the outside air, are kneaded by the palms of her hands...?
