John slithered into bed with Kelly and wrapped his tail around hers.
"Snake tongues are fun" said John "but what you really want it is a penis in you, don't you?"
Kelly looked at John. "How did you know?"
"Because I'm craving cock too" admitted John. "I'm only going to be a female lamia for a few days. I'm really curious to know what it's like. Besides, the only other way to give you what you want is either a sex toy or me going 48 hours without sex so I transform back to my old form. And I'm not ready to go that long yet."
"We just have to be sure you don't get pregnant!" warned Kelly. She got her smartphone to text Henry.
"Wait, let's make it really enticing" suggested John.
Kelly held out the smartphone as far as she could before taking the photo of the two lamias kissing and groping in bed. She sent it to Henry with one word: "Hurry."
