However, since he was planning on working at the university library, he dressed comfortably yet respectably, wearing sandals, shorts, and a nice short-sleeve shirt. In fact, he reminded me somewhat of some of the grad students, especially carrying his laptop in the shoulder bag.
On arrival at the library, I alerted my supervisor about my big brother's plan to work there for the day, and possibly over the next few days as well until the heat wave abated, and she was fine with that. In fact, she even gave Eric a special username and password for the network -- until that moment, I had not known that the library had a set of rotating network logins for single-day usage, although they were really intended to be used by non-campus people doing presentations in the library's meeting rooms.
After clocking in, I went with my big brother up to the top floor, and we went directly to the private study room the furthest away from the stairwell and the elevators. I spent a few more minutes with him as he set up the laptop and ensured that he could access the network, then gave his cheek a quick kiss, intending to return downstairs.
Before I could reach the door, however, Eric stopped me. From behind, he wrapped his arms around me, his hands on my breasts, squeezing, fondling. I froze, for I was in plain view of the window -- if someone else was indeed on the same floor, I would be very easily seen, and while I did not mind that my big brother was feeling me, I did not want anyone else to know that he was more than just a big brother to me. Fortunately, his manipulation of my chest only lasted a few seconds, before he released my breasts and kissed the top of my head, but it was enough to make me want to spend the day with him, just sitting at the table and watching and listening to him work, and it took all my willpower to give his hand a quick squeeze before I left him to his duties while I went to fulfill mine.
At lunchtime, we ate in the shade of the same tree where I had so often eaten lunch on my own. Instead of talking via cell phone with my big brother, he sat next to me, his laptop bag prominent between us as if to reassure anyone passing by that he and I were "just" big brother and little sister. As we ate and chatted, however, I noticed several women and even one guy eyeing Eric with obvious interest, and I truly felt honored just to be in his presence and on the periphery of such positive attention.
In time, however, Eric had to go back upstairs, back to the private study room. Again, I accompanied him, and again, before I left, he felt me, this time by backing me against the wall, trapping me there, gazing deep into my eyes and even deeper into my soul as his hands massaged my breasts and moistened my thong.
"Please..." I whispered, wondering if my big brother could feel the hardness of my nipples through the bra and the blouse I wore that day.
"Maybe later," he taunted, giving each breast a final, harder squeeze as he kissed my lips.
The afternoon dragged on until, finally, my shift had ended. After clocking out, I headed back upstairs to the study room, finding Eric was leaning back in his chair, his fingers interlaced behind his head, a smile spreading across his lips as I entered the small room. Most interestingly, however, he had moved his chair to the one corner which could not be seen from the window if the door was closed.
