女性が快楽に夢中かつ無防備であるのがわかりやすく、とても好きなシチュエーションです!目が見えないのが難点ですが、舌出しやポーズ、震え、汁などの表現を使い、エロさを補強できます。
Dear Patron.
I like this situation very much because it is easy to see that the woman is engrossed in pleasure and unprotected! The drawback is that we can't see her eyes, but you can reinforce the eroticism by using expressions such as tongue sticking out, posing, shaking, and juices.
