In college, I had the good fortune of having two of the younger sisters of friends. The first was my sophomore year roommate. I had met her sister several times when we were freshmen. She lived in the city where we went to college and was planning on coming to our school when she graduated high school, so she came up to visit and hang on on campos. She was slender, short but with perfect perky b cups. Long beach hair, pouty lips and amazing dark eyes. I usually don't go for Italian/Mediterranean types (I prefer blondes and redheads) but she was gorgeous. We flirted a good bit but never came close to doing anything, and I wasn't really interested in pursuing a high school girl.
The following year, her brother and I roomed together and she moved into the same coed dorm we were in. One of the first weekends of the year, her brother was at his parents house and she needed a lift to the store to get some supplies for her room. I was happy to oblige. We spent the afternoon shopping, laughing, having a great time. When we got back to her room and unloaded her bags, I knew I had to see what could develop so I invited her to a party I knew about that night. She instantly said yes.
