As sweet as it is kinky, Bottoms Up will propel you to pick up a paddle and share in both pleasure and pain, or perhaps simply turn the other cheek. In "The Hardest Part," Alison Tyler perfectly captures a sub in thrall to a man who knows the power of anticipation. A "Sorority Sister" bends over to please her big sister during the rush season in Dominique Dunbar's naughty tale. Zille Defeu's "Reenactment" shows how some girls like it rough (and repeatedly). For those who have an endless capacity to bare their ass in preparation for a sound smacking—or deliver the deliciously ecstatic pain to a lover—this torrid tour de force is essential reading.
