Bound in pain, erotic agony: a story of a 21-year-old's submission

In the dimly lit fantasy dungeon, a beautifully tanned, athletic girl of 21, her body an intricate balance of anorexic slimness and bulging muscles, stood bound in black leather boots, collar, and numerous bondage straps. Her abs were very visible, contrasting with the huge belly bulge. Her small breasts, adorned with nipple piercings, erect nipple areolas pointed out under her oily skin. The large labia framed a gaping pussy, dripping with cum, a highly detailed vagina that housed a large, aroused clitoris. Her legs were spread wide, stationary, and restrained, as a sex machine relentlessly penetrated her painfully, causing a grimmace of pain mixed with surprise and horniness.
