After assuming control of Jen's body, Sam got a terrible idea for how to take advantage of the curse that she twisted to her own advantage. She went home and looked up the mailing addresses for many supermodels and celebrities and sent letters to these addresses. These letters were personalized to the recipient, with each one stating in big bold print "You are not " followed by the name of the targeted celebrity. In doing this, Sam ensured that the letters would be true if they were opened by the celebrity's publicity team, but would be a lie if the celebrities themselves were to personally read them.
Although these letters were nonverbal and indirect, the fact that they contained untrue information written by Sam was enough to trigger the curse. Of course, not all the targets would fall for this trap and would instead have their staff members read it and discard it, but some of the people she wrote to ended up reading the letters personally, and became a part of Sam's growing cabal of cocks.
The plan would not stop here, however, as Sam would then be able to force her celebrities-turned-penises to spill all of the credentials of their bank accounts and, more importantly, their social media accounts, which would allow Sam to impersonate her dicks and tell more lies to other powerful people, adding them to her roster. This would also give her another chance to try and absorb some of the celebrities that didn't read her letters, thanks to there now being direct communication.
For now, though, Sam has already absorbed 5 people using her letter writing scheme, and some of them are none too happy with their new situations...
