Liz is so aroused she begins to stroke herself

While Josh was lost in thought, Liz uncounciouslly began Running her hand over her semi erect cock. This was the first time she felt this sensation and began to get lost in the lust, eyes rolling back in her head. Her other hand ran up her taught thighs to her now full B cups, playing with her nipple.

A animalistic moan began to come from her the back of her throat.

The moan caught josh’s attention and for a moment he couldn’t believe what he was seeing. The silhouette of his toned and curvy sister. One hand fondling her new breasts as the other strokes her now full hard cock.

Her cock at full mast was now 9” and as thick as a D battery. It was so engorged the veins looked almost concrete.

“Liz... what are you doing” Josh managed to stammer.

Liz partially snapped out of the pleasure, but she no longer felt as much shame as she had when her body began to change.

“Oh sorry brother, is this what having a cock feels like all the time? How do you deal with all this pleasure and pressure? I feel so backed up.”

That’s when josh noticed her balls, hanging low, each the size of a golf ball. They were oscillating on their own from what seemed to be a huge amount of new cum being circulated.

“Uh well, actually .. I do what you were just doing. It’s just uncomfortable to see my sister doing it.” Said josh.

“Why, because you know your cock could never satisfy a woman’s half as much as mine” said Liz in an uncharacteristically assertive town.

“I’m sorry Josh” Liz immediately stammered. She was confused by her emotions and what she just said. “I don’t know where that came from, I’m just a little lost right now, I don’t think that. All this pressure is making me act funny.”
