Step-by-Step Guide
The receiving partner lies face down on a firm surface with their hips slightly raised — a thin pillow under the hips creates a subtle downward angle for the penetrating partner.
The receiving partner can keep legs together for tighter sensation or slightly apart for easier entry — the prone position naturally compresses the vaginal canal.
The penetrating partner kneels behind and enters at the slightly downward angle created by the hip elevation, targeting the G-spot through the anterior wall.
Use a grinding, bumping motion rather than thrusting — the penetrating partner grinds their pelvis against the receiving partner's buttocks, creating rhythmic pressure waves.
The receiving partner can push back slightly with their glutes to control the intensity of each bump, or remain still and let the penetrating partner control the rhythm entirely.
Maintain full chest-to-back body contact throughout — the Speed Bump is about the grinding rhythm and full-body connection, not deep thrusting.

Common Mistakes to Avoid
Even with the right technique, small errors can reduce pleasure or increase injury risk. Here are the most common mistakes couples make with the Speed Bump position:
Thrusting instead of grinding
The Speed Bump is named for its bumping, grinding motion. Sharp thrusting misses the point and reduces the rhythmic, wave-like G-spot stimulation that the grinding creates.
Hips too flat without elevation
If the receiving partner's hips are completely flat, the downward angle is lost and the G-spot contact diminishes. A small pillow under the hips maintains the correct angle.
Receiving partner lying completely rigid
While the prone position is passive, the receiving partner should use their glutes to subtly meet each bump. Lying completely rigid reduces the rhythmic feedback.
Neglecting the full body contact
If the penetrating partner lifts their chest off the receiving partner's back, the intimate, grinding feel is lost. Stay pressed together for the full Speed Bump experience.
Variations to Try
Once you've mastered the basic Speed Bump, these variations can add new sensations and keep things exciting:
Add a Pillow
Place a pillow under the receiving partner's hips to change the angle of penetration and enhance stimulation.
Incorporate Manual Stimulation
Use hands to add clitoral or other external stimulation during the position for enhanced pleasure.
Slow Down the Pace
Switch from thrusting to grinding for a more intimate, sensation-focused experience.
Try Different Surfaces
Move from the bed to a couch, standing, or against a wall for different angles and experiences.
