Failed Panty Raid

When the college semester ended, I had to help my sister move out. After she moved out, I made sure to keep the backdoor of her apartment unlocked. She then left town and I went back and snuck in. I went upstairs to her roommates' rooms. The one that was cute had completely moved out so her room and closet were completely empty. The super hot one only partially moved out. Before I even step foot in her bedroom, I stripped down naked at her door. I then preceded to check everything out in her room. She just left her desk, chair, dresser, bed, two plastic drawers, and a stretching rack. I got excited when I saw her dresser because I wanted to steal some bras and panties but was saddened when I found out every drawer was empty. I checked the plastic drawers and all I found were sweaters, and cold weather gear. I did find some workout shorts and bra. I set the workout bra and the softest sweater I could find to the side for me to take home later. I then grabbed more sweaters and threw them onto the bed. I climbed in bed with them and started to masturbate with them making sure to cum where her head would be. While I was doing this, I was imagining slamming her down on her desk and pushing myself into her. Having her on her desk, riding me in her chair, against the shower wall, obviously in every position in bed, and even her stretching rack. After I had my fun, I put all of the sweaters back except the one I set aside to take. I left a note on her desk pointing to a condom and wrote "Let me know if you wanna have some fun...". I look back and wonder what else I couldve done.
