Let them have their fun.

Well you are hornier than you've ever been. And you really don't like the sound of them casting some spells on you. You nod to the girls and show yourself to the girls. Your body is burning up as you see them women taking you in. From your blush to your tits. You can feel your nipples almost quivering. You know they at this point would be able to cut glass. Your slit is not one to miss out on the embarrassment as it keeps twitching and aching over and over again.

The three women quickly disrobes as they stand naked before you. Their bodies are clearly what you would describe as absolute perfection. They all withdraw their wands and you lock in place. "B-but i thought you said if i did this you wouldn't curse me." You stammer, clearly feeling some kind of betrayal. The leader of the gang seems to laugh a little. "Oh aren't you cute! These aren't for you" and with that they all three put their wands to their groin and mutter:"evig em a kcoc". The result is immediate as you see a rather large cock spring forth on each girls mound. "These are" she finally laughs as the transformation is complete.

Though scared you can't help but feel that, a spell like that could be useful later, and you mentally add it to your spellbook for later use. As you do so the girls have gotten quite close to you.
