Ben decides to choose a couple of the options there. He selects the Tail , muzzle, and fur options and puts "Tiger" after them. After giving it a second thought he then goes to the Increase Size option and selects Penis: Tiger, and then hits the submit button. Immediately he begins to feel warm all over and notices changes on his arm.
He is growing black and orange fur on his arm. The shock was pretty bad until he felt a tingle above his ass. In desperation he pull his pants off and stands in front of the mirror. His ass is covered in the tiger fur and also a tail is begining to grow.
He thoughtlessly scratches his nose and feels some whiskers but the tingling in his groin calls for attention. He looks down over his new muzzle and see a sheath forming around his penis as it grows. He also notices that some barbs are growing on the head of his penis as it slides into it's new furry home. Oddly enough this begins to arouse him and his penis begins to grow as it comes out of it's new sheath.
He had suddenly become VERY horny and he began to wonder what it would be like to jack off with this newfound penis...
