She does

Katja couldn't remember the last time she let someone get so carried away with her body like this. Robert was snacking away on her tits like a pie-eating contest and for some reason his complete happiness was infectious and she was feeling quite light headed.

For some reason she thought the right next step was to even the odds.
"Take out your dick."

"Huh wha?" The teen tried to speak around a mouthful of boob.

"Take your dick out it's only fair since I have my tits out."

"Ok!" The teen quickly unzipped himself and released his raging member.

Taking it in her hand Katja played with it, her hands seemingly moving on their own as she jerked off the teen as he continued to play with her boobs.

Katja kept masturbating in time to his sucks as he would move from boob to boob trying to cover the entirety of her tits.

Her naughty behaviour was really turning her on and she could feel how wet she was becoming through her panties. The feel of a hard rod in her hands only exacerbated her condition.
