Stretchy Tailhole-
"His fuckhole was modified to have a tight and
flexible ring, self-lubrication and cleaning
properties, and increased pleasure and nerve
sensitivity. Such an expensive modification
allows for his primary sex organ to be prepped
for use and abuse of any scale at any time."

Numbed Dicklet-
"In contrast with his height, Zachary
decided to have his little 3 inch cock
numbed and feminized to enhance and
focus on pleasuring his other parts,
fitting a submissive slut like him."
