What it is

Grow a Girlfriend is a novelty expandable polymer figure that delivers genuine comedic shock value. Start with a compact 2-inch figure, submerge it in water, and watch it balloon to 12 inches over several hours. The flesh-toned polymer is non-toxic and engineered to handle multiple expansion cycles without degrading, so the joke never gets old. See the full BDSM Australia range of Sex Coupons for more ways to spark laughter and connection.

What sets this apart is its simplicity and repeatability. No batteries, no complicated setup—just water and time. Once fully expanded, let it dry completely and it shrinks back to pocket size, ready for the next reveal. It's the kind of item that works equally well as a prank, a party centrepiece, or a standalone gag that keeps delivering laughs.

How to use a sex games, coupons and trick

Remove the figure from its packaging and place it in a container with enough space for growth. Submerge it completely in room-temperature water and let time do the work. Over 4–6 hours, you'll watch it expand gradually—perfect for building anticipation at a party. Check on it periodically and remove it once it reaches your desired size, then pat it dry with a soft towel.

For maximum impact, time the reveal strategically or set up a time-lapse video to capture the transformation. Experiment with water temperature to adjust expansion speed, or try partial submersion for creative shape variations. Once you're done, allow it to air-dry completely in a cool spot, and it'll shrink back to pocket size. Pair it with Sex Balls or other novelty items for a complete party entertainment package that keeps guests talking.

Keep the figure away from children and pets, and ensure it dries completely between uses to prevent mould or material degradation. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

After each use, allow the figure to air-dry completely in a cool, dry location away from direct sunlight. Store it in its original packaging or a sealed container to protect it from dust. Rinse with mild soap and water if needed, but avoid harsh chemicals or abrasive materials that could damage the polymer. Proper drying between cycles ensures years of reliable expansion and comedy.

Mistress Athena's training notes

Psychological transformation fascinates me, and this figure embodies it perfectly. Placed strategically in a submissive's environment, its potential for growth creates mounting tension without a single command. I've observed how anticipation of change registers as genuine anxiety—a powerful tool in mental conditioning.

The polymer's gradual expansion mirrors the subtle intensification of control I employ in my practice. Submissives become hyperaware of this seemingly innocent object, their focus sharpening as it grows. Some freeze in nervous anticipation; others become obsessively watchful. Each reaction reveals their psychological threshold.

What intrigues me most is its reversibility. After drying, it returns to its original state—a metaphor I use deliberately. Control, like this figure, can expand and contract. The lesson lands quietly but profoundly. Submissives learn that nothing remains static, that transformation is always possible, and that awareness itself becomes part of the power dynamic.
