"Oh, I can't wait to see what this does!!" She said that with a really happy tone. He could easily see her eagerness in every thing she did.
"What's it supposed to do?"
"Well, I can't tell you right now, it's a surprise! Do you want to see it now?"
"Why not!"
At this point, she started to instruct him about what they'd have to do. She brought him to their bedroom and they took off all of their clothes. Lastly, she proceeded to lock the door, and put the key on the bedside table.
"Alright, then! We can do whatever we want now!"
"Oh, that's cool! Why do we have to be naked, then?"
"You'll see. Why don't we watch TV for now?"
"Sure"
She then laid down on her side of the bed, legs spread wide, while him tried to find something on TV. Honestly, he wasn't really able to contain his excitement, as he thought they were going to have a great time, but did a great job so far.
In the end, he managed to find a movie channel, and started watching, even though he was lowkey hoping she'd do something like she'd done until now. He was right. She got off the bed, and said in a dominant tone:
"Ready?"
Nothing more.
She then proceeded to sit on his laps. Every second she could notice his cock growing. She started massaging, and proceeded to pick up pace. Her ability was incredible: he was already about to cum! The moment she felt that she turned around and slid his dick into her balls deep, and they fucked, for about half an hour, non stop. The weird thing was the thickness of both's fluids, which was never seen before.
"So, this is the surprise, right? "
"No, of course."
"What?"
"Just look, it's about to happen!"
As she said that, she then massaged once more, to get him to cum once again. Once that was happening, she had a taste. This time it was even thicker! And, before it got sprayed all over the place, she slid his cock into her asshole, which somehow fit perfectly, and just in time for the super thick cum to enter her. The sensations were great, for both, but in the end, he couldn't pull back out.
"Weird, huh?"
"No, that's the surprise! Well, or at least, part of it"
"What do we do now? I'm stuck!"
"Let's sleep on top of that!"
And so it was, the couple sleeped, the two hugging each other, one stuck in the other.
But, when the morning came....
