The next morning Weiss and Ruby were sleeping when they heard a knock on the door. Ruby got up and slipped on Weiss' shorts and a hoodie and answered the door.
"Huh Weiss I thought you were in bed." Ruby said as she looked back to see Weiss still in bed and this other person whom looked just like her standing in front of her.
"One moment please." Ruby said as she shut the door.
"Weiss there is someone who looks just like you and is absolutely gorgeous standing outside our door." Ruby panicked as she shook Weiss' shoulders.
"Looks just like me huh. Oh shit that's Winter." Weiss yelled. Weiss grabbed clothes and jumped into the bathroom to shower.
"Ruby let her in distract her." Weiss said.
Ruby went to the door and let Winter in.
"So you're Weiss' sister I've heard a lot about you. Weiss is in the shower she'll be out shortly." Ruby said trying to start conversation.
"So you're Weiss' play thing." Winter said.
"No not exactly we're dating." Ruby said.
"She doesn't use you just for sex?" Winter asked.
"Um no we've been dating for a few months now and we just had sex for the first time last night." Ruby said.
"Well then I guess I could say she's pretty lucky you're quite attractive." Winter said putting a finger under Ruby's chin.
Just then the door of the bathroom swung open.
"Winter!" Weiss yelled still in a towel.
"Hi baby sister." Winter said.
"She's not a sex toy." Weiss said.
"Awe but she's hot." Winter said.
"I know she is but I love her and I don't use her." Weiss said sitting next to Ruby on the bed.
"You love me." Ruby gasped.
"Yes of course." Weiss said.
"Awe I love you too." Ruby said and locked lips with Weiss.
"This is sweet, let's have a threesome." Winter said.
"No." Weiss said
"Sure." Ruby said at the same time.
"Are you serious?" Weiss said looking at Ruby.
"Yeah why not it'll be fun, it won't be weird she's your sister." Ruby said.
"That's exactly what makes it weird." Weiss said.
"No don't think of it like that it's just for fun I have more than one hole for you two." Ruby said.
"Your serious." Weiss said blushing in disbelief.
"I guess I'm ok with it." Weiss said.
"Are you sure because if you aren't then we won't." Ruby said.
"Yes but keep it down it may be Sunday but there's still people here." Weiss said.
"And no kissing Ruby, Winter she's mine." Weiss said.
"That's fine though I would have loved to." Winter said.
Winter removed her clothes what seemed to be at light speed, and Weiss dropped her towel. Looking at the two sisters Ruby became nervous as she thought she saw a lightning bolt come between their eyes looking at each other.
Ruby slid off her hoodie and shorts.
"Jesus Christ you're huge." Ruby said as she held up Winter's still limp dick.
"Twelve inches when I'm at my best." Winter said.
"Well maybe this will help." Ruby said as she bent over the bed.
"Come here Weiss." Ruby said.
Ruby had Weiss in her mouth while Winter entered her. Winter entering Ruby made Ruby moan onto Weiss. Ruby was going insane from the pleasure. Winter then flipped Ruby over and pulled her close till their breasts were pushing together, and Weiss came up behind and stopped at Ruby's entrance of her ass.
"It's tighter back there and may hurt a bit."Weiss said.
"Just be slow." Ruby said through moans.
"Well it'd be easier if Winter would take a break for a moment, and she better still be as tight as she was last night or I'll be pissed." Weiss said.
"Well I'm sorry your girlfriend is to wittle for my size." Winter said.
Winters thrusting caused Weiss to forcefully enter Ruby's ass making Ruby moan extremely loud. Weiss covered Ruby's mouth and Ruby's eyes rolled back as far as they could.
"Oh man are you lucky baby sister, you've got yourself a little sex fiend here." Winter said.
"What do you mean." Weiss said.
"Well instead of feeling pain she went into pure pleasure." Winter said.
Weiss started thrusting and Ruby stuck her tongue out from pleasure.
"Oh I'm gonna cum." Winter said.
"Me too, you better not finish inside her." Weiss said.
"Ugh I'm not an amateur baby sister." Winter said as she pulled out and came on Ruby's tits as Weiss pulled out and came on Ruby's back side.
"Sorry winter my ice princess tastes better." Ruby squeaked before passing out on the bed.
"Ha." Weiss said.
"No matter I made her cum three times." Winter said.
"But one was from you when you stuck it in her ass, damn you're an animal baby sister." Winter said.
Weiss just gave up at that point and laid back down with ruby covering both of them after wiping down Ruby with Weiss' towel and started to drift to sleep.
"Welp I've got part of Dad's company to run, this was fun. Till next time." Winter said as she left.
"Weiss I just want you to know this doesn't change anything, you're still the only one for me babe." Ruby said as she kissed Weiss and went back to sleep.
Weiss was ok with it since at least if anybody it was her sister and drifted off as well.
