Mark had been in his graphics class for a couple weeks, he sat at a table with girls, all his friends none he would ever try and bed.
One day a transfer student came in, she was short, shoulder length blonde hair maybe a bit longer, she was wearing the classic "school girl" outfit. Long-sleeve button up white shirt, plaid skirt about knee length and thigh high white tights. She introduced herself as Katie and sat at their table. Mark couldn't keep his eyes off her she was so gorgeous.
Later the graphics class was delving into photography and they were learning about black room's and film and such. The school had a black room, which is the red lighted room that pictures are developed. And it also had a BLACK room where the film is taken out of its cartridge and put in a wash/formula container. All this must be done in the dark, complete darkness.
Well the instructor's rule was nobody can go in there alone, and that its two small for 3 people, so pairs of two from each group only. Mark's group had split up the chores of developing the pictures on the groups one roll of film. The other two girls decided they would do the container formula stuff when Mark and Katie get out of the BLACK room.
Today Katie was wearing a grayish tank top with a print of "Mischievous" across the front. She also wore a short black skirt.
There were stools outside the BLACK room and Mark and Katie sat waiting for another group to get done.
Mark peeked down her medium low cut shirt and saw a nice line of cleavage and breast shape inside a black silk bra. He tried to keep eye contact as they were chatting but he couldn't.
Finally it was their turn in the room. They got in, put the roll in front of them, put the tools they needed in front of them and then turned out the lights, put the occupied sign (also the lock) on and took apart the film.
Complete darkness made Mark's other sense's stand out. He smelled her, a sweet perfume, he heard her fumbling with the film. She dropped a piece on the ground.
"Oops" she coyly said.
She bent over to pick it up and her ass got placed right at marks pelvis.
