“Well what if we, ya know, try her out?” Peter asks. “I mean sure it’s you in there, but like you said her body needs be tested out. For science. Make sure everything is, anatomical. Right?”

Their dad nods, “You may be right, son. We can try something.” Peter gets excited and quickly drops his pants.

Dad turns around and looks down at his youngest son, seeing his tiny cock standing at full erection. He can’t help but laugh, “Come on, that can’t be all of it? Are you tucking or something? No way a son of mine has such a small cock.” Peter blushes and turns red, “Is that thing even 2 inches? How are we supposed to test out this body with that? It would be like trying to stitch leather with a thumbtack.”
