She had been dreading this night ever since she learned about it. The older sorority sisters called it a character building exercise, but the pledges just saw it as embarrassing. They had 6 hours to run around town, collect a phone number from each fraternity house, and then return a photocopy of the phone numbers to their big sister. The awkward part was that the signatures were to be collected on their chest.

All week the sorority sisters had been teasing the pledges, questioning them if they had enough space on their tits for 10 phone numbers, and if they had any experience flashing. It was already hard enough being looked at by so many of the frat boys as a piece of fresh meat. The idea of just standing in front of them with her tits out while one of them wrote their number on her skin was difficult to mentally prepare for. The thought of it was tremendously embarrassing, but also somewhat exciting. The plan was to travel as a group of 4 pledges, with two older sisters to be their escorts. The four pledges were not wearing bras.

They rang the doorbell at the first frat house, and were led into the living room. One of the older sisters addressed the room full of guys.

“Attention young men of the house.” The ritual announcement began. “It has come to our attention that these four pledges have been suffering from a lack of socializing. As responsible and supportive older sisters, we have brought them here tonight in the hopes of collecting some phone numbers, so that over the next few weeks they might have someone to call and ask out on a date.” The guys enthusiastically agreed to help.

“Are there any pledges here who would be willing to give their phone number and help out a shy sister?”

The fraternity had already planned for this, and had explained the procedure to the incoming pledge brothers. Four of the new fraternity pledges had been selected ahead of time. They took their seats in four chairs. The four sorority pledges walked up and stood, one in front of each chair. After one more deep breath, the four women each took hold of the front of their shirts and lifted them up to their neck. The room went silent, with all fraternity brothers frozen, eyes widened in disbelief. The collective gaze darted back and forth between the four pairs of breasts now on display, desperately trying to save this visual to enjoy again later. The 4 seated guys each had a pair of bare breasts at their face level, and it took all the self control they could muster to behave in a dignified manner. They uncapped their pens carefully, and began to write their phone numbers on the delicate flesh.

She was aware that as a C-cup she was in the middle of the range of breast sizes on display. The other three pledges were probably an A, a D, and then a quadruple D, or whatever letter the world assigned to sizes that had too many Ds. The guy in front of her was right handed, and carefully brought the tip of his pen to the skin of her left breast. The instant he made contact, her nipples decided on their own to scrunch up tight and poke forward. She clenched her teeth, trying, but unable, to wish away her titty hard-ons. He paused briefly to admire their transformation, then he began writing. He wrote his number up high, respectfully, a few inches above her areola. He was very careful to make the numbers legible, as he was hoping to see her again. After writing his phone number he started to draw the circle as he had been instructed to do. Beginning at the last digit, he slowly traced a large circle clockwise, down the side, around the lowest part, and back up to meet at the first digit. The result was a large circle, with her nipple in the center of the bullseye. The lucky guy at the next house would choose to place his number above or below the first number, and then draw another circle either outside or inside the first. The circles were not to cross, but form concentric rings around her nipple. At the end of the evening each breast would resemble a topographical map, with ring lines designating the slope of the terrain, and each elevation identified with a phone number. Those who chose to write close to the areola drew a small circle. Those who started higher on the chest traced a longer path all around her perimeter.

As he drew his circle, she looked around the room at how transfixed all the fraternity brothers were. They were silent and motionless, stuck in a boob induced trance. It felt like she had a super power. Her tits commanded attention.

When he was done she looked down at his handy work, then at him, and gave him a slight smile of approval. He was sort of cute. Not exactly handsome or hot, but might be worth a date someday. She lowered her shirt and took a deep breath. One down, nine more to go she thought to herself. Only when she started walking towards the door did she notice a wetness between her legs. The thought of baring her breasts at the next house was now one step less embarrassing, and maybe a step closer to arousing.
