Hey! This is a prompt (or collection of prompts) that could be played together in the same story or individually if you have a favourite.

Truth or Dare.
Two stepsiblings have a bit of a flirtatious and troublemaking streak. During a stay at the family cottage, they sneak a bottle of liquor up into their shared bedroom. While the snow coats the outdoors through the window, in the warmth of their room, they sit on the edge of their bed and come up with a little drinking game. Truth or dare, and if you want to skip a dare or truth, you take a shot. If nobody skips in a round, they both drink. First one to call it quits is the loser, granting the other bragging rights and maybe even a prize. Slowly over the course of the night, they mix in questions getting to know one another with teasing dares, each slowly pushing the line further and further.

Seven minutes in Heaven:

You host a party with your friends, various girls in first year of college and one or two guy friends of yours. You didn't realize your older brother, whose house you're staying at, would be interested in playing. You certainly didn't expect the girls to be so eager to invite him to play seven minutes in heaven after everyone was good and buzzed. The rules were simple, you'd spin a bottle to determine who went into the walk-in closet in the next room for seven minutes. The pair that got to leave the closet gets to choose the next pair that goes in, etc. However, older brother ends up being a little bit popular in the game, taking one of your friends after the other, even away from their boyfriends, into the closet. The early rounds, most of the guests in the closet leave breathless, having been made out with deeply, groped pleasantly or fingered to a quick orgasm. As the night wears on, each of your friends gets broken down, until you're pretty sure they're leaving with your big brother's cum dripping out of them. Imagine the look on their faces when one of the girls calls your name and mine...

Chicken:
Well, nobody thought we'd still be living at home at this age, with school and everything happening from home for now, and money being tight, both you and I still crashed with our folks. It seemed permanent enough that mom and dad deemed it appropriate to renovate your bedroom, expanding it along with a few other parts of our small humble house. It meant we basically had to share a bed for a month.

The first night however revealed a tension in the air between us neither had ever explored before. As I got out of the shower, smelling like fresh mint body wash and my brown curled hair towel-dried and still wet, I slipped on a pair of dark red boxers and a white crew neck, and opened the door to my bedroom to see you on my bed. We looked at each other, and instantly, the dynamic felt... different.

We ended up chatting, not able to sleep. "What about a game?" I had proposed. "I'll put a finger on you somewhere, and move it. When it gets too close to somewhere you don't want me to touch, you say 'chicken'. We take turns - the person who lasts the longest without saying chicken, the most times in a row, wins."

Regardless of who wins that night, we rematch the next night. Soon we're playing in the middle of the day, under everyone else's noses, whenever we can. Soon we're not just using our hands, and hell, we're hardly saying chicken. Better up the ante...
