Mike reached up to his girlfriend, now the naga of his dreams, to pull her into a kiss. Emily lowered herself slightly, but kept ever so slight a height advantage over her human boyfriend. They kissed at first, arms around each other holding their bodies close. Finally pausing for breath, Mike pulled his shirt off. He went for his pants next, but Emily grabbed him and tossed him on the couch behind her. This caught Mike by surprise, unfamiliar with both Emily's newfound strength and such aggressiveness by her. Mike unzipped his pants but Emily yanked them off before he could remove them himself.
Emily took a moment to tower over Mike on the couch, enjoying the reversal in their roles. Their lovemaking was never particularly rough, but Mike normally lead things. Emily was giving Mike his snakey fantasy, but in doing so had found other unexpected advantages for herself.
Emily lowered herself on Mike's rigid member and took a moment to stroke it with her long, snakey tongue. Mike clearly needed no help in the moment, but Emily was going to see what she could do with her new tongue. It's flexibility amazed her and allowed her to perform pleasure in ways not previously possible.
"Oh yessssss..." moaned Mike, in ecstasy over his dreams come true and unintentionally hissing his s's.
Waiting no longer, Emily slid atop Mike on the couch and slid Mike inside her. She was on top for once!
It was a new experience for both of them, Emily's tail giving her muscular control she didn't have as a human. The both of them enjoyed every moment of it, better sex than they'd experienced before.
Emily had transformed to let Mike experience the snakey fetish she'd long suspected and he'd finally been unable to deny with her new form. But now Emily was unsure she wanted to change back. But that was a question that could wait until after sex was finished.
