Kylie Jenner -- Tyga Marks My Spot (PHOTOS)

Kylie Jenner posed for famed photographer Terry Richardson while showing off a ton of cleavage ... and a conspicuously/perfectly placed stuffed tiger doll.

Kylie and Terry shot a spread and cover for the latest issue of Galore magazine. She also did an interview with the mag, and acknowledged ... "For me, age is just a number."

We'd say Tyga agrees.
