Bob told Kim not to talk again, or she would be punished again. Throughout all this he noticed her nipple clamps were gone. He found them on the floor...and attached the clamps again, this time slightly tighter. The sting was there, but she really loved the tingling her nipples felt under the clamps. Bob then got on top of her and straddled her waist. She could feel his shaved balls on her stomach, please lick my pussy or fuck me she thought. Bob picked up the tiny whip he purchased, he brushed. Her pussy was slick. Like Teflon on wet ice.The familiarity of her movements again brought back distant memories from the past. I could imagine her moans of pleasure but could not hear them over the music in the background. In a burst of passion, I unbuckled my belt with my right hand. I then unfastened and unzipped my jeans and in a single downward movement pulled down my jeans and underwear. My pulsing hard-on was now ready for adventure as I guided the tip down her soft butt crack and slick. .. oh... OHHHH!" Mark panted as Erin continued thrusting inside him, until she finally gave a final, prolonged thrust and they both collapsed onto the bed.Neither said a word as they lay enjoying the afterglow of their amazing orgasms."That was... fantastic." Mark eventually said after sometime."Yes it was." Erin said smiling back at Mark as she brushed her hand across his cheek."OH MY GOD!" Mark shouted when he caught sight of the ring on Erin's finger. Grabbing her hand and holding it, they. The magical beings bred like... well, rabbits seemed almost chaste in comparison. Every hospital in a college town now had a vastly expanded maternity ward, as Fairy females were carted in every day, bellies bulging with half-breed young. Seasoned gynecologists gaped in shock at the sheer number of offspring the females could grind out from between their fertile thighs.It was during a visit to a hospital on behalf of her mother that Nancy got the idea. While waiting in the Maternity compound.
