Ananova:

Boffins have invented a sex toy that connects up to an iPod and vibrates in time to the music.

The vibrations get faster as the music gets louder on the £25 iBuzz, reports the Sun Online.

Ali Carnegie, of adult-store www.LoveHoney.co.uk, said the firm is already on the verge of selling out of the bullet-sized device before Christmas.

She said its inconspicuous design has been a big winner with women and claims the sex toy, totally unrelated to Apple, is perfect for giving users "big smiles on their way to work".

Jessamy Hawley, of Gadget Candy - a technology website aimed at women - believes combining two female passions is sure to prove a No1 hit.

She added: "The iPod is this era's must-have accessory, while a vibrator is a timeless addition to every girl's gadget drawer.

"Entwine the two and you've got the ultimate cheeky Christmas stocking filler."
