The next hour and a half were excruciating. The longer I waited the hornier I got thinking about what was happening, what she was doing to him, what h... might be doing to her. I went into the bedroom and pulled up one of her favorite videos and stroked myself until I was about to cum then stopped when I heard the door open. I pulled the sheets up on the bed and just lay there like nothing was going on. She walked into the room and said nothing as she began getting undressed. I finally asked. Three more cuts followed and then as Stacy took a rest. I took the opportunity to massage Zack’s bottom, which was by this stage reddening and nicely marked. Rest period over, Stacy picked up the birch, I suggested that the next six cuts be delivered in one rapid burst. She delivered them skilfully, Zack’s body arched and while it was clear that he wanted to scream out, his pride stopped him. We then took time to admire Stacy’s handiwork, Zack’s bottom was scarlet and a number of angry welts. He unzipped his pants and exposed this huge, fat cock. It was the biggest one Id seen and much more fun looking than what my boyfriend had going on. I wanted that cock, all the way inside me, NOW. I straddled him as he shoved it up into my waiting entrance. He rammed that entire giant pole into me in one full thrust. I rode him so hard and fast. He fucked me as hard as he could with that big glorious dick of his. I was so hot and turned on, Id never cheated on a guy, but this was exquisite,. She looked straight into my eyes and said yet again in her sultry alluring voice-“I want to give you something….show me your hand”….just then, a tata safari came out from the mail alley to pull up into the parking slot nearby…she quickly kept something in my hand and asked me to keep it in my pocket at once….she started her car once again and drove out in a hurry….So much had happened in the previous one hour that i was struggling to get a hold on it….i peeped down a luscious busty cleavage.
