・ナリタちゃんの弱点メモ
勃起前の乳首は非常に柔らかく、その状態で強制的に引っ張り出すことで最大級の性感を与えることができる。
勃起前に比べて掴みづらいので、大きな手と強い握力が必要。
Note on Narita's weakness.
Pre-erect nipples are very soft and can be pulled out forcibly in that state to give her the greatest sexual sensation.
They are more difficult to grasp than before erection, so large hands and a strong grip are necessary.
