Also known as: 股コキ, 素股
A sex act in which a girl grinds her bare or clothed Pussy against her partner's Penis without being penetrated.
This is different from Imminent Vaginal. In Imminent Vaginal, the penis is angled to penetrate, while here, the pussy is simply rubbed against the penis with no apparent intention to penetrate.
If both participants are clothed, use Dry Humping instead. For Penis-between-thigh rubbing, use Thigh Sex instead.
