She brings Michael home, where she has set out two glasses and a bottle of champagne. Pouring the bubbly, Verena struts to the living room, where she gives Michael a longing look before passing him his drink. They toast, and then a moment later Verena has set her glass down and pulled Michael in by the tie for a kiss.Leading Michael by his tie, Verena takes him to the bedroom where she pulls her dress down to pop her full breasts from the bodice. Her nipples are already had as Michael kneels behind her and helps her peel her dress the rest of the way down. Crawling onto the bed, Verena lets Michael relieve her of her high heels. Michael doesn't waste any time; he takes advantage of Verena's position by diving on in for a taste of that meaty pussy.Verena wants to enjoy Michael's fuck stick, but now that Michael has had a taste of that puss he's not about to stop. They compromise, with Michael getting onto the bed and pulling Verena on top of him. Leaning forward, Verena wraps her hand around the root to pull Michael's dick in for a blowjob that completes their 69.Eventually, Verena climbs off of Michael's face and arranges herself so she can just blow her boyfriend without any distraction. She loves the feel of Michael's big cock in her mouth. As she's sucking, though, Verena can't help but wonder what it will feel like to have the D buried inside her. She decides to find out, swinging herself on top and mounting him in reverse cowgirl.Verena gives riding Michael her all, thrusting her hips in a sensual rhythm that leaves her twat dripping wet. Falling onto her side, Verena pulls Michael close so that he can slide into her as he spoons from behind. That deep penetration hits all the right stops as Michael captures Verena's lips in another carnal kiss.Rolling back onto her hands and knees, Verena watches over her shoulder as Michael settles himself behind. Anchoring his hands on Verena's hips, Michael slides all the way inside. He holds nothing back, delivering a proper pussy pounding in Verena's cream filled fuck hole.As she reaches the end of her endurance, Verena rolls onto her back where she can watch as her big dick boyfriend gives her one last climax. As soon as her twat is pulsing with orgasmic bliss, Verena resumes her blowjob from earlier. Michael rewards Verena's diligence by popping his load all over her face to give her a big cumshot to play with.
