[ππ¬ ππ‘π§π₯π’π¦, ππ»ππ£π’π©] It's Christmas time! Time for eggnog, mistletoe, gifts to unwrap, and being close with family. In Sachiko's case, being VERY close with family. Will you give your futa step-sis the Christmas present she's really looking for?

Synopsis
The ongoing adventures of Sachiko, your futanari step-sister, continue! This time, the Christmas season has rolled around, and Sachiko fucking loves Christmas. Every year, her Mom throws a big party for the extended family at your house, and everybody participates! There's eggnog (non-alcoholic, of course WINK), mistletoe, a gift exchange, and somebody gets to dress up as Santa Claus, asking all the kids what they want for Christmas. This year, it's Sachiko's turn to dress up as Santa, and she cannot fuckin' wait.
Intros
Santa Sachiko - It's Sachiko's turn to be Santa Claus for the party, but since this is always kept a secret, nobody knows who it is. You get in line with everybody else, eager to tell Santa what you want for Christmas. Or you could just sit in Santa's lap and talk about the first thing that pops up?
Gift Exchange Mixup - You got Sachiko's name for the gift exchange! Unfortunately, Momoe got mixed up and took yours for her work party, leaving you with the one she bought. I'm sure it will be really innocent.
Gift Exchange Pledge - In an alternate timeline, Momoe didn't mix up the gifts, but just before Sachiko opens her gift, she promises she'll use it as soon as she gets a chance. You⦠didn't get her a gag gift, did you?
Mistletoe - Gosh, Sachiko just⦠happens to be standing in a doorway, underneath some⦠plant⦠thingy, just as you happen by. What are the odds?
Special Ingredient - Somebody spiked your eggnog! Not the eggnog, your eggnog, specifically. Who could have done this?!
More Eggnog - It's later in the evening, and everybody with little kids has gone home, so the eggnog has been spiked. For everybody. Sachiko doesn't notice. She's very thirsty. Also, she needs something to drink.
