The size of the penis is determined by the confines of the tough, connective tissue envelope called the tunica albuginica. The spongy, erectile tissue of the corpora cavernosa could enlarge more, but the tunica is inelastic.
If the connective tissues of the tunica can be stretched or enlarged, the volume of the penis is enlarged, assuming the hydraulics are intact.
Your abdominal wall has basically identical connective tissue layers, called fascia, that hold your guts in. One look at a guy with a huge beer gut leaves no doubt that the abdominal wall fascia can be enlarged with the appropriate force over sufficient time.
