Princess Leia's youngest son, Anakin, has a cock that's enormous. Perhaps too big. (Damn midichlorians!) So per doctor's orders, it's up to her to make sure her son is masturbating regularly to keep his balls empty and his levels balanced. Leia is a mother that's happy to take her son's... health into her own hands.This commission was for the cover of Pyro's Leia's Motherly Touch story which you can find here.
(Well worth reading, he's an excellent writer.)
