Tina Morgan, the teenage nerd from next door

"Oh my god!" the eighteen-year-old cried a second later when her eyes focus on your hard cock gripped firmly in your hand. "What the hell?"

Unable to cover yourself, you stare at her in shock, still holding onto your erect penis. From behind her glasses her eyes stare back, darting from your face to your cock. You willed yourself to get soft, but you were becoming so trained at being excited by humiliation that it actually felt like it was getting harder.

You'd be telling a lie if you said you hadn't jerked off thinking about her before. Despite being something of a prude, the type that wore baggy khakis and loose fitting polo shirts to school every day, you'd seen her in her parent's pool a few times in her ill fitting one-piece. Beneath the khakis and polo she was consealing a nice body.

"Uh...look Tina...I can explain..."

"What kind of pervert are you?" she asked. "You couldn't just go so that ten feet away in your house?"

"Please...let me..."

"Just wait until my dad gets home!"

"Please, Tina, don't tell your dad," you beg. "I'm sorry you found me like this, I had no idea you were even around. Lets just forget this ever happened."

"I won't be forgetting this anytime soon," she said, her eyes going back to your cock. "It's not every day I catch a grown man jerking off in front of my house."

"Please, I'll do anything to keep this a secret," you tell her.

"Anything?"

"Yes, anything," you promise.
