[Gold Plan]
Blindfolds and hand restraints are lighter forms of SM play, so if you're in a relationship with a partner, you might go along with it pretty easily, especially in the early stages. However... engaging in a threesome or more is not something most people get to experience often, right? Haha.
拘束プレイのいろいろ
目隠しとか手の拘束は、軽めのSMプレイなので 付き合い間もない恋人同士なら、ノリノリでやってしまうでしょうね。ですが・・・3人以上の複数プレイは、そうそう経験できませんよね?w
