"Ladies, please line up in an orderly fashion! How many times do I have to ask?" Sister Anne hollers above the noise of 25 giggling girls. "If you expect us to make the most of our day, you will need to follow instructions!"
We are going to the Natural History Museum today to collect information and ides for our term project. The excitement is because we get to leave the school for a day. It's a rare occasion that we are allowed off campus and we all want to make the most of it. I grab Rebecca's hand and pull her into the line. Sister Anne walks past us, clipboard in hand, checking names off the list. Our eyes meet briefly and I see the corner of her mouth pull up in a knowing smile. She catches herself, and moves on.
"So, maybe we'll meet some guys today," Rebecca whispers in my ear. "I haven't been with a guy in ages. I'm so horny."
I laugh, and whisper back, "I'd love to try it out."
The bus pulls up to the curb and we begin filing in. Rebecca and I take the one seat at the back and settle in. In morning traffic, it will probably take us thirty minutes to get to the museum. As the bus pulls away, Sister Anne stands at the front, to the right of the driver. She's talking about the rules of our outing.
Suddenly, I am distracted. I feel a warm hand sneaking up my thigh, beneath my skirt. I shift my legs slightly, spreading them to allow access. Everyone else has eyes forward, paying attention to the lecture on good behaviour expected of young women of St. Katherine's Academy. Rebecca's attention is elsewhere. Her index finger is stroking my pussy over my white lace panties. I can feel myself becoming wet as she begins pressing harder. She moves her hand to the edge of the fabric and begins to slip her fingers beneath. My breathing is quickening and I suppress a gasp as her finger flicks against my throbbing clit. The other girls on the bus are oblivious.
Sister Anne is mentioning something about our lunch hour, but her voice is far away as Rebecca slides a finger into my wetness. She is stroking my inner lips, moving my fluid over my clit. My whole body is tingling with excitement at the though of being fingered by Rebecca with my classmates only feet away. Rebecca suddenly thrusts her finger deep inside my pussy. I gasp quietly, moving my hips ever so slightly to the motion of her inside me. Her other hand is caressing my tit over my sweater, pinching my erect nipple.
The sister has now taken her seat, and the girls around us begin to talk quietly. I can hear the two girls in front of us talking about which exhibits they are interested in. The only thing I am interested in is Rebecca's finger. Her pace has quickened, sliding in and out. Her thumb is pressing my bud rapidly. I am holding my breath, so as not to pant or moan. I look over at Rebecca's face and she gives me a naughty grin. I spread my legs further and she adds a second finger to my dripping pussy. I am getting so close to cumming. I wonder if I can do it quietly.
Rebecca's fingers are working furiously inside me, when the bus driver suddenly applies the breaks sharply. I cum suddenly, calling out and shaking uncontrollably, but my cries of ecstasy are lost amongst the other girls' screams.
"Sorry about that ladies!" the driver calls out. "Someone swerved in front of me. Everyone alright?"
Everyone is fine, and we continue on our way. I look over at Rebecca as she slips her fingers out of my pussy. I shudder slightly. "That was close," she says. "I don't think you could have explained that outburst!" She brings her fingers to her tongue and begins cleaning them off.
Soon we arrive at the museum. We file off the bus and proceed into the lobby. Sister Anne is saying we are free to move about the building, gathering information for our essays, but we must all meet in the lobby at noon for lunch. Rebecca and I begin wandering toward the Egyptian exhibit.
"That was incredible, what you did to me in the bus," I say quietly to Rebecca, as she jots some notes on her pad. "Thank god nobody noticed."
"It was exhilarating, though, wasn't it?" she giggled.
We continue further into the exhibit, looking at a display of hieroglyphics. Behind us I can hear a group of people whispering. I glance over my shoulder and see three boys watching us. I smile, and turn back to Rebecca. "Hotties at three o'clock!" I hiss. She casually turns to her right and looks at the boys. I can see her lick her lips and wink at one of them. Turning back toward me, she continues to take notes. I elbow her softly in the side and call her a slut.
As we move through the museum, the boys follow us. I can feel their eyes on me as I take off my sweater and lean over to stuff it into my backpack. I undo the top three buttons of my blouse and pull my hair out of its ponytail. Rebecca grins naughtily.
During lunch, I can see the boys at a table from the corner of my eye. They're talking, with their heads bent together, glancing over at us frequently. Rebecca smiles at them and waves covertly.
We are finished eating and head to do my research. It's quiet in the neolithic exhibit when we arrive. We stand in front of a display featuring a family of four sitting around a fire, their rawhide shelter behind them.
"Hey there, girls," I hear a quiet voice behind me. I turn, smiling at the tall guy behind me. He has deep blue eyes and dark hair. He's looking down at me, a mischievous look on his face. "Where are you two from?"
I look at him through my lashes, and say coyly, "St. Katherine's". I see his friends nudge each other behind him. "Where are you from?" I ask.
