This is old movie with Alex. Usually Alex was never permitted to smooch woman higher then knees. But he was a good boy and can be rewarded. Of course he cant pretend to kiss Elena without clothes, but kiss her panties is good enough for him. So Alex kisses Elenas panties and smells her aroma, aroma of the real woman! However the slave is unexperienced, because he never kisses woman, even in panties. And Elena teaches him, she grabbed him by the hairs and hit him with a whip. After that lessons she hopes that Alex can be good in panty kissing too.
