Skull fuck refers to vigorous or aggressive oral sex. The term refers to the way the receiving partner fucks the giver's head (or "skull"). A skull fuck can happen to anyone, regardless of their gender.
Porn star Johnny Toxic is credited with coining the term skull fuck in the early 1990s. He used the term as an alternative to the common adult industry terms "forced oral sex" and "brutal oral sex."
The person receiving oral sex during a skull fuck may grab their partner’s head and push their penis down the giving partner’s throat. They may then thrust their hips to move their penis in a backward and forward motion to "fuck" their partner’s skull. The receiving partner usually keeps hold of their partner’s skull with one or two hands during a skull fuck. They may also put their hands lightly around their partner’s throat to control their head.
While it is less common, skull fucking can also refer to intense cunnilingus. During this kind of skull fucking, the partner giving oral sex usually lies down on their back. The receiving partner then straddles them and rides their face, ensuring their genitals make intense contact with the giving partner’s mouth. Skull fucking with fellatio can also happen in this position.
During a skull fuck, the partner receiving oral sex usually takes a more dominant role than they usually do during oral sex. Keeping hold of their partner’s skull and thrusting their hips helps them control the depth and speed of the skull fuck. In contrast, the giving partner often stays still. A receiving partner may initiate skull fucking because they want deeper penetration during oral sex. Skull fucking can be arousing for both partners, as it makes the receiving partner feel powerful and the giving partner feel vulnerable.
The term skull fuck is a variation of the term "face fuck." However, "skull fuck" suggests more intensity than "face fuck" does. The term skull fuck can also refer to the act of penetrating someone’s eye socket with one's penis. When used this way, skull fuck is usually part of a threat against someone rather than a real sexual practice.
