At next Dustin makes some adjustments, so that everyone remembers him and Thea this way and that his parents and everyone was okay with the fact that he is sleeping with his foster-sister.
Dustin also wishs that Thea obeys to every command from him additional to her submissive nature, just to be sure.
Then Dustin considers rhe possibilities. It was weekend and he still got some time before dinner.
Perhaps he should go to the mall with his sister. Or he could go to the park. Or perhaps there are some other things he could try with his new powers.
But first of all he should help his sister with her 'problems'.
Cause for the last five minutes while Dustin plans out the next steps, Thea lays on his bed and, cause Dustin seems not avaible, pleased herself. The need builded up in her since her transformation and Dustin's change back and his new slightly improved sight only increased her nymphomanic desires.
Dustin notices it and begins to undress. Than he slowly begins to fumble with her bouncy breasts, knowing that she can't expect to be mounted. Slowly he uses hi tounge and fingers and moves his way down to her crotch where her fingers increased her wetness. Finally he reached her clitoris and Thea moans in relief. Then Dustin begins to prod her vagina with his dick until he finally plunged it in and starts with rhythmic movements. Thea's moans becomes louder and she reached her first orgasm very quick.
She get three others until Dustin finally cums and collapses next to her in the bed.
While he lay there and think about the future Thea is busy sucking the last drops of his dick.
