Alison Tyler’’s latest collection of erotica is sure to put the spark back into any intimate relationship. She’’s gathered couples’’ most popular fantasies and created a sizzling, no-holds-barred series of explicit stories in which twosomes transform their deepest desires into flesh-on-flesh reality. These powerfully written stories meld the nasty and the sweet to fill a full 24 hours of sex, from early morning wake-up calls through mid-afternoon quickies to late night romps. In “Black Light,” a hidden webcam turns an intimate encounter into a thrillingly public viewing. A sexy 1970s dress and a tantalizing series of notes (“NO PANTIES, PLEASE”) lead to a satisfying reward for an afternoon’’s housework in “Disco Dream.” Featuring stories by Sommer Marsden, N.T. Morley, Jordana Winters, and Teresa Noelle Roberts, Afternoon Delight is filled with sex around the clock.
