Girth

"We should also check to see if your cock is thicker than before," Jane said. She hastily lifted her bikini over her head, allowing her perfectly round tits to bounce free.

"The gap in my cleavage can hold up to 3.2" of hard cock" she said. "Let's see how you measure up."

Sam grabbed his hefty meatstick at the base and push himself into the space between Jane's soft breast balloons. As he'd predicted, he fit like a glove, just barely pushing her chesticles apart. Big as he was, the head of his cock found its way right in front of her lips. When she spoke, it was as if his manmeat was a microphone.

"Oh my god it's perfect. Exactly 3.2 inches!" She said, looking up at him. She used her arms to push her tits together and lock him in. "We should see if you're just as thick from base to tip," she said, smirking. She bent forward, sliding her tits down Sam's pole.

As she descended, she let his big mushroom tip spread her lips wide and enter her mouth. She managed to get most of the way down, before gagging on his cock, creating a drizzle of thick, sloppy spit that ran down his veiny tower. Then she changed course, lubing him up as she massaged his cock with her rising tits.

"You taste delicious!" she said when the cock freed from her mouth. "That has to be part of the change. Cock isn't supposed to taste that good."

Jane slid her tits up and down Sam's cock, sucking him on the downstroke and pulling off on the way up for a good five minutes. With every trip, the blowjob got sloppier and titfuck got faster. Sam put his hand on the desk to keep his balance, as every bit of his big rod was tightly swaddled by soft flesh.
