Trained by his Futa Stepmother: A Taboo Futa-on-Male Story (His Futa Training Book 1)

Colin is thrilled to be dating his adorable girlfriend, Cammie. But with the physical side of their relationship progressing, he's worried that that he'll prove too inexperienced and unskilled to please her the way he wants to. But when he turns to his stepmom for advice and help, he gets far more than he bargains for. While Sarah is more than happy to train him, her methods will turn his world upside down.

Now, thanks to a strange potion, Colin has a warm, wet secret between his thighs and his stepmom is sporting a gargantuan new appendage. But, then again, what better way is there for an eager young man to learn what women like?

But while Cammie is delighted by his newfound skills, Colin quickly finds that his stepmom's training program is going to be way more intense than he ever could have expected.
