子宮をノック
Sex where the male (or futanari) penetrates their partner balls deep - all the way to the base, with the entire penis inside the vagina or anus and only the testicles visible. Cross-section or x-ray shots often show the penis resting against the cervix, if not outright cervical penetration.
The following tags are aliased to this tag: balls_deep (learn more).
