John needs to use the restroom!

"Just a second Katie", John said, “I need to use the restroom."

"Um", sure Katie answered hesitantly, "It is straight up the stairs at the top."

John hurried up the stairs his cock throbbing painfully in his tight jeans. He needed to jack off now, or he would not be able to concentrate on anything else. Katie was so hot he didn't want to blow it with her by having a huge boner all night.

He closed the door, and unzipped letting his erect cock spring into view. He had a nice big cock, and as he squeezed its fat head pre-cum oozed out lubricating it as he started to masturbate. He thought about how perfect Katie's ass was, and how he would like to put his hands under her ass, gripping it tight, as he fucked her tight cunt. His cock was fully erect and ready to explode. The shaft was thick and hard with veins popping out, and cum dribbling from its head.

Suddenly he spotted a flash of red on the floor next to the tub. It was the panties that Katie had taken off. John could not believe his luck, picking them up and put them to his nose and took a deep whiff. He could smell her pussy, and he then wrapped the panties around his hand stroking his balls with the soft fabric of the panties as he started to pump his cock again.

He started to imagine how perfect her tits must be, how firm they were, how the nipples would look all hard and erect. He could feel his balls tighten, and he brought the panties up to his nose so he could smell her pussy again as he began to ejaculate. The first stream shot from his cock with great velocity and splattered on the mirror in front of him.

Suddenly the door burst open and there stood Katie, "John are you about ready...” She trailed off as she saw what he was doing.

"What the fuck are you doing with my underwear", she yelled as she watched the rest of his cum spew into the sink. "Are you some kind of pervert?" she continued as John tried desperately to get his still hard cock back into his pants.

Katie stood there breathing hard red faced. John was red faced too from the embarrassment of getting caught jacking off with her panties.
