Help with homework

I asked Eileen for help with my math homework. Numbers weren't sticking in my head that night. She came over. Instead of opening the textbook, she slipped her fingers under my skirt and found how wet I already was. Her touch moved slow, then firmer, like she knew exactly what I needed. Eileen leaned closer, breath warm against my ear, while her free hand traced the line of my thigh down to my foot. She lifted it gently, pressed a kiss to the arch, then let her tongue follow the same path. My toes curled. The math could wait. Eileen clearly had different lessons in mind.
