Lying in a teenage boy's bedroom and teasing her rigid length took Gracie back to a similar time in her life, when she was freshly out and still had a lot of changes to make. Then sixteen, the girl was staying home sick from school and doing homework while listening to music on her headphones. Nobody was home for the sound to disturb, but there was something she liked about the isolated feel of it. Gracie was working on a short biology essay when a thump from the next room over had broken her out of her reverie. It must have been her older sister, Allie, taking some lucky young man home while their parents were away. The younger sibling must not have heard them enter the house while she was in her own personal world of academia.<br/><br/>They became increasingly difficult to ignore as the thump of Alyssa's headboard against the wall was followed by the faint squeaking of boxsprings and the rising din of moans both masculine and feminine. She should have done something, made her presence known, turned up her headphones, left the house, anything but what she did. Which was to turn her music off, strip down, and lie back on her bed, rapidly pumping her swollen girlhood. Gracie visualized every sound, every clapping thrust, every groan of pleasure, every shake of the bed. Her mind had to fill in some blanks, of course. Their position, Allie's nude form, the man pounding an imprint of her into the mattress, and how well-endowed he must have been since many of the elder sibling's panted adulations were about how big he was. Jerking herself with usual teenage impatience, Gracie was covering her stomach in thin spurts of cum barely a minute after starting. All told, she repeated the process three times before the pair next door finished their tryst and said their goodbyes.<br/><br/>Back in the present, Gracie knew she was at her peak and decided to finish off with her favorite memory of those days. The first and only time she heard her sister, in no uncertain terms, tell a lover to put it in her ass. The image of the very body she wanted so badly for herself being plowed in a way she could personally empathize with always set her off quick and strong, and this time she had several days worth of seed to cover herself with. After her quick clean up, Gracie had no problem sneaking back into her bedroom and enjoying a good night's rest. She was awoken, as usual, by Toffee excitedly licking her face just after sun-up.
