Hard as hell!

Big boy and Evelyn enter into the lab and see Biter laying on his back with his cock sticking straight up into the air. Evelyn let's out an excited squeal and runs over to the table. Biter's nuts are large and heavy looking. Evelyn gives them a squeeze and his cock jumps in response. She claps her hands and runs over to her desk and takes out a tape measure. She measures it first lengthwise and then wraps it around to find girth. She starts scribbling everything down on a clip board and then lifts her head to look at Big boy.

"Great news! It seems like everything worked. Now we don't know until we actually see him put it to use but I think this proves your not a one off. Now he's only about 12 inches long but he's 7 inches around . He very thick for his size! He doesn't seem to have quite as much fluid as you do and his musk isn't as strong but everything else seems right."

Just as she finishes her sentence the sound of voices and boots stomping start coming down the hall. Evelyn's face looks confused before recognition and then worry appear.
