Robin and the Warlock Hex

Robin has really done it now! While sneaking around a Wizard's room she comes upon a Hex potion that she decides to steal but drinks it once she gets caught. Uknown to her it's really a hex that makes a huge cock grow out of. The only way she can get rid of it is if she cums 100 times! So she gets right to work and plowing everything in her sight! Can she use this giant cock for the good of the world?!?
