Erotic literature

Marielou sits on her bed with the book open across her thighs, spine cracked wide. She doesn't hear the door or the two girls stepping inside. Page 142 holds her complete attention. The sentences there describe a woman being fucked against a library ladder, legs spread, her wetness leaving a slick trail on the polished wood. Marielou's lips part. Her right hand rests between her legs, not rubbing, just pressing, keeping the pulse of it. She turns the page with her left thumb. A new paragraph begins: the man pulls out, come trailing down her thigh, then pushes back in. Marielou swallows. She shifts her hips once against her own palm. In the doorway the other girls stand very still, watching the way Marielou's free hand drifts up to touch her own nipple through the thin cotton of her tank top, pinching it once, twice, in rhythm with whatever she's reading.
