Another sex tape shows Kanye as a stallion!

A stallion:  Kanye West

Perhaps, here finally is why Kim Kardashian cannot get enough of rapper, Kanye West. A new sex video just emerging shows that the superstar is a 'marathoner'. 

The rapper is facing more embarrassment as another X-rated video is allegedly being shopped around which shows him participating in a 40-minute lovemaking session with a beautiful brunette.

Kanye was "freaking out" after the first tape emerged last week, featuring him and girl who looks like his current girlfriend Kim Kardashian, and this second recording is double in length.

TMZ.com reported: "Both tapes are impressively long - the first is roughly 20 minutes and the second is more than 40.

"And we're talking constant action. Seriously, the guy takes no breaks. It's incredible."

Both tapes were made before he started dating 31-year-old Kim - who was catapulted to fame after becoming the unwitting star of her own sex tape in 2007 when her ex-boyfriend Ray J released the recording.

The 'Stronger' hitmaker has called in his lawyers to stop any footage of the tapes from being released, and it is believed the material has been stolen from his personal computer.  

With regard to the first tape, his lawyer Lisa Buckley released a statement confirming it is Kanye in the video and warning against any party distributing images or clips from it.

She said: "Your posting, advertising, marketing, displaying and otherwise disseminating the stolen screen shot and/or other materials on the tape constitute actionable violations of Mr West's rights of privacy and publicity".

World's most expensive relationship: Kim and Kanye burn N619m in four months

In just four months of dating, Kim Kardashian and Kanye West have forked out £2.5million (over N619million) on each other.

Some West African countries have not seen that much money this year.

The Mirror reported the ego-stroking spendaholics have become so obsessed with flashing their cash at each other that they’ve forked out £1.25million each on cars, holidays and other pressies.

Only dating officially since April, their romantic gifts to each other have included:

A £478,000 black Lamborghini which Kim bought Kanye for his 35th birthday in June;

A £21,000 white sapphire-encrusted gold skull statue which Kanye gave Kim in July;

Plus they’ve spent £446,000 on just getting to their many holidays in London, Paris, Cannes and Mexico by private jet or first class.

The two are reported to be very strong-willed and there is a bit of a power struggle in the relationship.

"Both Kim and Kanye want to show they have their own money and fame outside of them getting together,” a source said.

“But they’re so besotted with each other that although they’re spending so much, they barely bat an eyelid when they see the price tag or bill.

“After all, they’re both multi-millionaires at the start of a big love affair.”

As Kim, 31, says: “When I’m in love, you can’t tell me anything. I’m in love with love!”

Mind you if it all leads to a Kimye wedding they’ve still got some way to go to top the £6.3million Kim and Kris Humphries spent on their bash ahead of their 72-day marriage back in August last year.
