"Well, if that is how your body reacts, then how about you flip around and show me a more...detailed reaction.?" he said, not even hiding how suggestive he was.
You signed and flipped around, your tail finally lowering a bit, but you know it won't be for long. Sam did some stretches of your uncircumcised penis, semi-flat at the moment, our round hairy yet slightly off-center testicles, and the shaggy man bush with a nice thick treasure trail. You stopped trying to maintain your body hair, if not most of your body, seeing as it just grows back after a shift.
"ok, I'm ready to see them, that Mighty pair of yours," Sam said, putting his drawing pad up.
You begin focusing on your groin, your hand stroking your cock to get the blood flowing to that area of the body. Your bush thickens into brown fur before spreading down your groin to your balls and foreskin. Your foreskin darkens and turns leathery as you feel your cock swell with blood as it turns a cherry red and grows a few inches as expected, but it is common to see changes like that for a lycanthrope. One of the things known to people about wererats, besides being one of the weaker forms of a lycanthrope, is their sizeable rodent-like ball sacks.
You groan as you feel your testicles swell up in size, filling like helium balloons as you try to give a slow change, so your friend can get what it takes his drawing of your member as it goes from man to beast. First, they become the sides of tense balls, then they are the size of apples than overripe avocados. After that, your seed slowly leaked out when they finally became their actual shape, big round grapefruit.
"that is amazing; they can't say you don't have a pair with jewels like that," he shouts as you try to get down from the pain and pleasure of having the body's most sensitive area pulled stretched like that.
