Drew walked into the locker room to change. He had just come from swimming in the school's pool and was wearing a swimsuit and a pair of flip-flops to keep his feet off the floor. Suddenly, he heard a female voice mumbling in the showers, as though talking to herself over the spray of water. He quietly snuck over, and looked into the shower area. The way the showers were set up, it used to be each shower head had a closed stall with 2 walls and a curtain. At the start of the year, some seniors in 1st period gym class had had an argument in class that had turned into a brawl in the shower area and ended with 2 seniors, in an attempt to break up the fight, had tackled the 3 fighting seniors into one of the walls. This had broken the wall, and sent it into the next one, leading a domino effect that ended with all stalls collapsing. After the rubble was cleared, it would be at least a semester before they got everything fixed, and in the meantime, only faculty and staff were allowed in the boys' shower area. Drew could not have been more thankful for that turn of events that he was in that moment. In the shower was Mrs. Weston, the school's head librarian.
She was in her late 30's to early 40's, a normally frumpy lady with a borderline unhealthy love of books who nearly always wore a cardigan, or rarely wore a school hoodie in its place. She was a bit heavyset, but with a rather large bosom that she couldn't hide no matter how hard she tried. She was wearing swimsuit bottoms, sandals, and no top. Drew saw 2 sets of clothing in piles on the far bench, and snuck over to see if he could find at least a bra size. He wouldn't pass it around school, but would keep it his dirty secret. He found one, and looked at the tag. Nothing. It was far too faded to read. After a little digging, he found the other one. He knew she hadn't seen him because she was still talking to herself. He looked at the tag, and got the same result. "Shit." He thought to himself. He repositioned himself on the side of the shower entrance near his locker, and quickly formed a plan to "accidentally" walk in on her. He peeked around the corner once more to make sure she was still unaware, and for a split second, watched the sides of her large breasts swing back and forth as she continued to wash herself. He took a deep breath to calm himself. "This is it." He though as he rounded the corner and acted surprised.
"Mrs. Weston?" He asked in fake surprise, resulting in her snapping around to look at him. At first, she forgot to cover herself, and he saw her full front, completely topless and exposed. Her breasts were larger than he expected, were round like torpedoes, and a pale white. She had faded tanlines that showed a top that only just covered the tops of her areolas, showing how close she had been to giving people a glimpse. They hung down, and while he couldn't tell if her nipples were hard or not, they seemed to point at his knees. They weren't perky, but didn't stare at the floor. They were large and stretched up and down, and were a dark pink. He could clearly see her areolas, but couldn't quite make out her nipples, at least not from a distance.
"Drew. What are you doing here?" She asked in shock, cupping her breasts with her hands so as to cover her nipples.
"Was swimming in the school's pool. Came in to wash off the chlorine before heading home. What are you doing here?"
"Was in the gym exercising. I'm trying to lose some weight this summer. There was no water in the girls' locker room, so I came here thinking I was alone."
"Well, I can already tell you're starting to lose weight, so whatever you're doing is working." He said, trying to go the charmer route.
"You think so?" She asked shyly, looking down over herself.
"Yeah. It's not much, but it's still noticeable. You look good."
"Well thank you. You're 18, right?"
"Yes, I am. Why?"
"How well can you keep a secret?"
"Locked up tighter than Fort Knox."
"Ok, good. Come here." He did as told. "Since you've already seen them now, here." She said as she dropped her hands, fully exposing herself to him again.
He looked at her large breasts and nipples, and immediately was fully aroused. Her nipples were flat against her areolas, and looked incredibly smooth.
"Can I touch them?"
"Yes, but be gentle. The hot water makes them very sensitive."
He gently cupped her soft, smooth breasts and moved his hands along them. They were soft, yet firm from the weight of them. He gently lifted each one, gauging their weight and softness. He slid his thumbs across her areolas and nipples, causing them to poke up slightly and harden. They didn't poke up much, but were rock hard when they did. He gently fondled and squeezed them, enjoying feeling them in his hands. They were the subject of the attentions and fantasies of many students, both male and female, and he was the first one to ever see them, and the only to touch them. "What size are they?" He asked.
