Caught by her Futa Stepsister: (Taboo Futa-on-female, Gender transformation)

Samantha has always looked up to her older stepsister Gabby, almost to point of being a little obsessive. This certainly hasn't changed, even now that she's all grown up and ready to leave for college.

While Gabby is enjoying the summer sun by the pool with her college friend Mel, Sam sneaks into her stepsister's room to indulge in one of her secret, naughty habits - something she really shouldn't be doing!

But when she's forced to hide in the closet to avoid discovery, Sam finds that she's not the only one hiding something. For Gabby has come back from college with a huge secret lurking between her legs - a secret that might unlock Sam's most private dreams.

Can Sam remain hidden, or will long simmering lusts will finally boil over?
