Nerdy bibliothekarin verehrt deinen schwanz

You know that cute girl that works at the library who checked out your books last week? The one that gave you that half-smile when she noticed you were checking out that adult graphic novel you both knew was filled with big-titted girls getting pummeled by huge animated cocks? That same girl you thought about later that night when you covered your hand and yourself with your cum? What you didn't know was that right around the same time you were emptying your balls thinking of her, she was emptying the balls of her boyfriend at home. The little stain on that cute sweater she was wearing today?
