Birth Preparation: EXTREME Pussy Stretching to 8cm dilation. Watch me stretch my pussy even further! I inserted the device and inflated it up to 8cm. This time I used a vibrating wand on my clit while the balloon was stretching me inside. This gave me an intense orgasm and made my pussy wetter and helped it to dilate even more! I then slowly pushed out the 8cm wide balloon. Almost like giving birth!
