Follow and find out

You follow Megan into a closet. She turns and locks the door behind you.

"So how would you like to fuck Hypergirl and more?" she asks.

"How could I not?" you respond.

She gives you an evil grin and explains about the ring you just made up. "All you have to do is slip this on your cock and fuck me and it will activate for the next 48 hours after that you have to fuck Hypergirl in multiple holes or it won't last"

"So put it on then," you say as you drop your pants to reveal your erect put relatively small dick. Thank god I made sure to add the size enchantment to the ring, you think.

Megan gives you another evil grin and drops to her knees. "Oh great goddess of corruption, bestow on to this man the your powers through the vessel of your ring," she intones as she slips it on. It fits perfectly, and with a wave of her hand she stands naked before you. "I still have a little magic left, at least until you fuck Hypergirl, but first you have to fuck me," she says.

With an invitation like that, how could you resist?

Grabbing her ass you lift her up and start pumping into her sopping pussy, shoving her against the wall you suck her massive, amazing tits as she moans beneath you. As you fuck you begin to feel the changes. Your dick starts to grow, and you feel muscles bulging as your super strength arrives. Soon enough you feel Megan cum on your dick, it's too much, with a roar you cum straight into her pussy. Megan gives a scream as you blackout from the waves of strength and pleasure you feel from the fuck. Your last sight before you slip into unconsciousness is Megan lying on her ass quivering with pleasure and that evil grin still on her face.
