Topless Kylie Jenner straddles boyfriend Tyga in racy picture to mark his birthday

KYLIE Jenner decided to wish her boyfriend Tyga Happy Birthday by sharing a very racy picture of the pair.

The shot – which tops even her raciest pictures to date – sees her straddling the rapper while completely topless.

Wearing just a pair of jeans she sits atop him, while the 27-year-old puts his hand down the back of the trousers.

He has his face in the 19-year-old's chest with his eyes closed while she has her eyes slightly open as she cradles his head.

Kylie – who missed his birthday last year because they were on a break - captioned the shot: “Happy birthday baby.”

The Keeping Up With The Kardashian’s star then shared another shot from the same shoot, showing them both laughing, writing alongside it: “Irreplaceable.”

Earlier this week Kylie started the birthday celebrations early - as she hosted a surprise party with Tyga’s four-year-old son King Cairo.

She captured the moment she surprised her beau as he walked into her kitchen to be welcomed by her and his son, from his relationship with Blac Chyna, wishing him happy birthday, with balloons, food and a cake.

Little King Cairo looked adorable as he bounced excitedly on the counter and jumped into his dad’s arms.

Meanwhile Kylie has been teasing a new secret shop with a series of very racy pictures.

The most shocking snap, which was posted to her Instagram account, shows Kylie laying in bed, smoking, in a pair of stockings.

In another of the seductive shots, only Kylie’s famous pout is visible of her face as she cups her own breasts in a sheer lace bra and leather jacket.

Wearing nothing but her sheer lace bra and a leather jacket, Kylie steamed up the camera lens as she linked to KylieJennerShop.com in all four pictures.

It is not yet known what the mystery shop will sell, but it seems likely it will be Kylie’s range of lingerie and other clothes.
