Her boyfriend had a huge cock, 9 inches long. The first time she saw him walk around naked, it made her feel really happy to have no cock.
It flopped around everywhere, hitting him in the leg all over the place. When he tried to wear briefs, his penis was squished against his pelvis. When he wore boxers, it fell into one pant leg, the tip poking out the end.
Having a penis looked so uncomfortable. Her crotch was so smooth and simple in comparison.
She slid her hand down her crotch, feeling the smooth flat skin, and she felt lucky.
