I kinda agree with this (especially the breasts) MC looks more like a Girl with a penis/ Futa, than a Sissy.
(Not really sure IF calling MC a Sissy is the correct term as this was done Involuntarily (He Still thinks He is a Boy/male)
- I am Sure that after serving 4 yrs in prison MC will walks out a Full-on Sissy slut!
And I doubt, very likely those meds the Warden are 'offering' him will make matters any better for Our MC.
About his penis,... Just because He's a Sissy Does Not mean THAT by Default he should have 2-3 in 'toy'/micro-penis.
(We have No idea what size his cock was before he started the 'meds'.
- Sure, the Fem Meds might have affected/shrunk some of his size...
but it is a Fallacy (Lie) to assume by default All Sissy's Must have a micro-penis. (just saying)
