Think of this story as taking place in a parallel dimension where everything is the same as our world except for... The Pin.
Heather Johnson and her mother were casually walking into the supermarket early Saturday morning.
"Mom, we don't need to get a cake. I'm not a kid anymore."
"I know, honey. You're eighteenth birthday is the most important day in a girl's life. You're officially a woman now. But everyone needs a cake for their birthday no matter how old they are. Let's stop by the bakery first. Since you're all grown up, you can help me pick one out."
As they approached the bakery, Heather recognized the man looking over the pastry selection. Even though he wasn't wearing his normal attire of a T-shirt and sweats, it was definitely one of the gym coaches at her high school, Paul Richardson. Heather always wondered how a gym coach could be so out of shape. The way he was ogling the bear claws behind the glass gave her a clue.
Paul noticed the motion of someone approaching and looked over. "Hey Coach Richardson," said Heather.
"Why hello Heather," Paul replied. He turned to her mom. "Maureen, good to see you too."
Heather's parents had known Paul for years, as he had coached their older son, Andrew, in basketball.
"Hi Paul," replied Maureen. Since Paul noticed Heather looking at the cakes, Paul asked, "Shopping for someone's birthday?"
"Yes, in fact today is Heather's 18th birthday today," said Maureen.
"Wow! Congratulations Heather!" responded Paul.
Paul's cock jumped at this news. In fact, it caught his attention enough for him to turn his whole body away from the pastry display. Now he was ogling Heather just as he was the bear claws before. And for good reason. Heather was very pretty, like her mom, and had a tight body only an 18 year old could have. He started at the floor and worked his way up: Skinny, tanned legs; perfectly shaped ass; flat stomach; and best of all she inherited her mother's C cup tits. They looked huge on Heather's small frame. He was tracing the lines of her bra under her shirt when he heard Maureen quickly say, "Well we have lots to buy. See ya."
Paul woke up from his trance. He quickly realized he was lost in lustful thought and the silence must have been awkward.
"Oh..uh..one moment Maureen. I see you are wearing your pin. Can I get a quick blowjob?"
