四十八手 理非知らず
本来は女の両手、両腿を縛ってから無理矢理犯す体位。膝を曲げた女の脚をそのまま抱え込み、自由を奪った状態で責める。別名、理知らず。
Originally applied to an unwilling woman. Her hands and legs are tied with ropes. The man stands on his knees, holds the helpless woman's bent knees, forces himself on her and successfully rapes her. This play can be enjoyed with or without bondage.
