"I guess we can start with dinner." Said James "Is it alright if I choose?" Sasha shrugged. "It might be your last meal, so it's really only fair that you decide." James turned to his discarded clothes and retrieved his wallet. "This should be enough. Know any good pizza places?" Sasha nodded. "Ever eat at Diablo's before?" James shook his head. "I'll call them, you just say what pizza you want." 
Five minutes later, the pizza had been ordered and the two of them were playing a video game while they waited for the delivery. James wasn't really paying much attention, as his mind was busy trying to think of a way to convince Sasha not to eat him. He figured that maybe if he made this night as nice as possible for her, and he was a true gentleman, maybe he might have a chance. 
They played for around twenty minutes until the doorbell rang, and Sasha ordered the house to unlock the door. She came back carrying a couple of pizza boxes, and motioned for James to move to the dining room. They sat across from each other, Sasha even helping herself to a few slices, saying it was an appetizer incase she decided to eat him later. James chuckled nervously, Figuring he may as well eat as much as he could, seeing as it may be the last thing he ever ate. 
"Alright, you mentioned wanting to watch a movie?" Sasha said upon finishing her final slice. "Yeah. Do you have anything good?" James asked, and she lead him to a cabinet full of DVDs. Examining them row by row, he settled on an action film and sat beside Sasha on the sofa. To his surprise, she actually pulled him in close and played with his hair with her claws as the movie progressed. "Not to push my luck." He said "But have you decided if you'll eat me or not yet?" 
"Not sure." Said Sasha. "So far on a scale of one to ten, I'd rate this date as a five. Maybe if you can raise your score before midnight, I'll consider making you my pet." Okay, James thought, I think I know how to get some extra points. He stealthily reached up and began to scratch behind Sasha's ears. She let out a small gasp, but quickly began to enjoy it, lightly tapping her foot against the floor as he continued. 
After the movie was over, Sasha looked at him and smiled. "Well, time for the last part of your request." James couldn't help but feel nervous. Half because he never had sex before, and half because she might eat him afterwards like a black widow. Sasha lifted him up over her shoulder and carried him upstairs to her bedroom. Placing him on her bed, she reached underneath it and pulled out a small box. Upon opening it, James saw that contained three small vials, each a different color. "What are those for?" He asked. 
Sasha picked up the green bottle and downed it in one shot. "Birth control potion." She said "Don't need you getting me pregnant. This one..." She picked up the pink bottle "Is a very special potion. After I drink it, it we'll have an adverse effect on my curves, while the blue one is for you. It will make your friend down there ten times as sensitive, so needless to say, this is going to be one hell of a night for you." 
James picked up the blue bottle and asked "Why are you doing this if you might decide to eat me?" Sasha chuckled "I've heard that having sex with your prey improves their taste. If I decide to eat you, you'll be all the more delicious. If not, then this will be a night you'll never forget. It's a win-win. Sort of." She downs the pink potion, and almost immediately, her hips widened and her breasts and butt swelled to nearly quadruple their normal size. 
James couldn't help but be aroused at the sight. Sasha giggled and said "Shall we have some foreplay first? Or do you just want to get right to it? I'll even let you be on top, since I don't want to risk crushing you."
