My sister always have her retarded College girlfriends over for sleep-overs. Sometimes it makes for awkward situations, since I boned quite a few. Other times, it's like a nice blast from the past, like with Kacey. Having already fucked around with her, she was familiar with my particular fantasy. She made sure she had a nice, isolated room in which to sleep in. While her friends were trading gossip with my sister, she made sure I would visit her during the night. Seeing that cute Blonde catching some Zs, legs already spread in anticipation, made me want to slip in a quick finger. She was so horny my finger came out glistening with pussy juice. We had such a great time that night we made sure to hold our own sleep-overs.
