Juan's hand grabbing and smacking May's ass sent a wild thrill through her, making her pussy grow warm in an instant. Like so many of the things she had done with Juan, and allowed him to do, being spanked was a new experience with May. Before dating him, she had considered it offensive and demeaning. And part of her still thought of it t he same way - but now she couldn't deny how much it turned her on.<br/><br/>May turned around and was about to lead Juan towards her bedroom when she caught sight of Lena - topless in the kitchen! A confusing mix of emotions crowded through May's mind in that moment. She was reflexively jealous, not enjoying the idea of Juan admiring another girl's naked form, especially when he began to make his appreciative comments. But she was also amused, almost laughing at Lena's deer-in-headlights look and the way the girl turned and started to hurry away.<br/><br/>More than anything, though, May was horny. She had been drinking, Juan had been playing with her in ways he knew drove her crazy, and a naughty idea had entered her mind the moment she had seen Lena naked. Images of herself as the center of a threesome, serviced like a queen, flashed through her aroused mind. Before Juan, Lena had given her some of the best orgasms of her life - she wouldn't deny that much. And the idea of somehow combining the two lovers into one night of passion, well...it was almost too tempting to pass up...<br/><br/>Juan commanding words and his hands on her body directed May down the path, turning her on even more and making it too hard to think of any reason why she shouldn't go through with it. She turned back to face him as he kissed her neck, and she didn't fight him as he started to pull up her dress, revealing the black thong that disappeared between the plump cheeks of her ass.<br/><br/>His spank sent another gush of pleasure into her pussy, and her mind was made up. She was flushed with desire and a bit of embarrassment, but she whispered to Juan, "I think she might be open to...hanging out."<br/><br/>Over her shoulder, while Juan toyed with her ass and kissed her neck, May called out in a voice thick with lust and alcohol, "Come on Lena, you don't need to hide. Come out here and join us."
