I was content just to snuggle and hug the night before we left Devil's Tower, but I had hoped for a little more action when I woke up with morning wood. No such luck, as Mom was already out of bed and breaking camp. I think she was trying to build up some sexual tension and anticipation, but I was already near peak on those two accounts.
Still, I played along and brought in the chairs and rolled up the awning. I tried not to think about the day before, which was impossible. I couldn't take my eyes off of her body as she went about cleaning up, bending over, or tiptoe reaching over her head, every move brought me a glance of her belly button or the shape of her boobs under her loose shirt, braless, her ass and legs in her tight shorts, her neck, and that still visible hickey I put there.
Once the RV was buttoned up, I pulled us around by the septic dump, then pulled over and plotted our course for the Tetons. I-90 to Buffalo and then leaving the interstate, it would take us all day to get there at RV speeds. We didn't have a reservation at Tetons, so figured we would have to call around to a nearby campground, hoping for the best.
It took a little more than half an hour to get to the interstate at Moorcroft. By then, Mom said, "I really have to pee." and started to get up and go to the back.
I decided that I wanted in on the game of anticipation, so I put my hand on her shoulder and said, "Wait, not yet."
"What's wrong?"
"Nothing's wrong. I want to play a game."
"Can't it wait until I go pee?"
"No," I said, "that's part of the game." I was making this up on the fly, but it worked.
She was curious enough to listen.
"What's the game?" she asked.
I picked up my full liter water bottle from my cupholder, unscrewed the top, and placed it in the holder on her side. "We're going to play 'Never Have I Ever."
I had her. She looked at me and her eyes flashed, and she bit her lower lip.
"Who starts?" she asked.
"I do. But not so fast. The next rest stop is in 80 miles. I'll pull over there and you can pee. And for every ten miles, I get to ask you a question."
"When do I get a turn asking?"
"You don't get a turn."
"Why not!?"
"Because I'm already hot and bothered. I need you to catch up."
Another lip bite, and a glance at my crotch. "So, in 80 miles, I get to pee. Ok. But what do you get?"
"I'll tell you when we get there. You'll have to trust me."
"Oh, I do NOT trust you!" But she didn't say 'no'.
I gave it another mile before I said, "First question: Never have I ever had sex with a teenage boy."
"That's not fair. I told you about my high school boyfriend." She complained, but she picked up the bottle and took a swallow of water. She didn't seem to be too desperate yet.
As the next ten miles rolled by, I could see her start to squirm. She pressed her legs together. She kept looking out the window at the mile markers.
"Next question: Never have I ever fantasized about my son fucking me."
She tried to just take a little sip, but I gave her a look and she tried again and took a proper swig. Just under seventy miles to go.
Ten more miles and she was pressing her thighs together. "Next question: Never have I ever leaked my juices on my son's cock."
She lifted the bottle and stared at me as she swallowed. She knew that she would be drinking every ten miles, but it seemed she couldn't wait to hear what I would call her out on next. It wasn't clear to me that all the squirming was just because she had to pee. And that was good, because my final demand would require that she be as horny as I was.
Still fifty miles to go when I said, without my eyes even leaving the road, "Never have I ever licked my juices from my son's cock."
She drank. Then she pressed her hand between her legs and applied pressure.
Forty miles to go. "Never have I ever swallowed a teenage boy's cum." That was only true if I didn't count tasting and swallowing my own, but she didn't challenge it. Her mouth opened as if she were remembering what it was like to suck her boyfriend's cock, how he tasted, and how he squirted onto her tongue. We were halfway to the rest stop, and she tucked her legs up in the seat. She no longer looked out the window. Her focus was on her own body and controlling herself.
I had figured out my last three questions miles ago. After another ten miles, I risked asking one I genuinely didn't know the answer to: "Never have I ever been fucked in the ass."
The question shocked her. She looked over at me with her lips parted, but she didn't pick up the bottle. Still, the next ten miles did their work, and she was really fighting to hold it in, while also rubbing and stimulating herself as she pressed down on her crotch. She moved one hand under her shirt and began playing with her tits.
Regardless of how she answered the previous question, what I really wanted to know was the next one. After ten long miles, I said, "Never have I ever fantasized about my son fucking me in my virgin ass."
She didn't' move at first. Then she shyly picked up the bottle and took a drink.
Only one more question, and then the rest stop would come up in a little less than ten more miles.
