How they compare
Both are among the biggest places for step-family roleplay, but they're built differently: Family Strokes is a dedicated network for the theme, while Adult Time is a huge streaming service where it's one genre among many.
Family Strokes bundles 11 series and more than 6,000 scenes, including PervMom, Sis Loves Me and Dad Crush, with new scenes every week in 4K. The scripts are light and often comedic, and the format repeats. It's $32.99 a month or $149 a year, streaming only; right now its Trick or Treat offer takes the first month to $9.95 and the first year to $99.95 (renewing at $149).
Adult Time costs about the same, $19.95 a month or $143.40 a year, but covers 60,000+ episodes from 400+ channels. Its step-family content is more story-led, from Pure Taboo's darker dramas to Mommy's Boy and Mommy's Girl, and you get every other kind of porn as well. Its $2.95 trial renews at $29.95 a month, so skip it if you know you'll stay.
