As they were kissing, Mackenzie felt Alex's hand slide down her back and under her skirt. He reached for her panties, grabbed the vibrator and seemed to insert it into her, pumping her with it. She moaned against his lips loudly as he fucked her with the vibrator while pulling her to his room. The door was kicked open with no problems, and Alex tumbled backwards over his bed, pulling her on top of him, deepening their kiss. He only broke it for a while to give her her orders.
Upon hearing them, Mackenzie straddled Alex's hips and began to rub herself on his length. His pants and her vibrator stood in the way, adding friction to her humping. As she did so, she smiled down at him as she began to unbutton her blouse slowly. When she was done, she slipped her blouse off her and threw it aside. Her full breasts were cupped in a black sheer bra, her nipples already hard with arousal. Reaching her hands behind her back, she unclasped her bra and slipped it off, releasing her breasts. Leaning downwards, she grabbed the base of Alex's shirt and pulled it over his head, licking slowly from his navel to his chest as she pulled. Now, for the bottoms.
Sliding off him for a while, Mackenzie stood beside Alex's bed, backfacing him. She unzipped her skirt from the back and deliberately wriggled her ass as she pulled it down off her, bending forwards so that Alex had a good view of her ass and her pussy from where he was lying. Stepping out of her skirt, she quickly pulled off her pantyhose, but left the thong on. Going back to Alex, Mackenzie undid his pants with her face as close to it as possible, sniffing his manhood. She pulled it down, smiling at the bulge in his boxers. Throwing his jeans aside, Mackenzie straddled his boxers and began riding it again, rubbing her vibrator along herself and him at the same time.
"How do you like that?" whispered Mackenzie in his ear as she rode him. Finally, she got off to pull down his boxers before straddling him again. "Tell me when you want me on you."
