Khloe Kardashian has a naughty idea on how to stay close to her L.A. Laker husband Lamar Odom when he's on the road: A sex tape.

In a clip of Sunday's Keeping Up With the Kardashians, Khloe, 25, says she wants to make a solo "sexy little video" (see video, above) so he'll have a way to remember her.

Sadly, her friend refuses to film it.

"That would scare me," snipes the pal.
