Take the ass, the Arc way

Jaune knew which hole he'd be using.

"Yeah, I wouldn't want to take your virginity away before you meet your special someone. But I like using the ass anyway" Jaune reasoned to himself.

Jaune looked to the bag of groceries he had. To do anal, you had to have lube and a lot of prep work otherwise it just hurts. But since Blake had Aura, he didn't need to worry about tearing her anal walls. But he still wanted lube to fully enjoy Blake's ass which was formed in the perfect globes due to her gymnastics fighting style

The tactician in him however, found a bunch of creative solutions. He looked to the ingredients that he could use as lube. There was:

• Coconut Oil, great for your skin as his Eldest sister Rouge taught him. His cock stiffened more remembering the boob-job she gave him using coconut oil. Now that he thought about it, Yang kinda looks Rouge, but with longer hair and less curvy.
• Whipped Cream, Slippery and makes for great blowjobs: He couldn't forget how he tricked his youngest sister Violet into sucking him off by blindfolding her and playing "Guess the food" as he sprayed whipped cream over his cock. She guess the taste right, but never the food and being super competitive, just kept licking the whipped cream off his penis over and over. She never guessed what she was tasting.
• Heavy cream, he knew how to make butter. All he needed to do was churn it in a vat.
• Butter, in his home country, butter was everywhere.

There was a whole lot more he could use, they were in the middle of the woods and the building has a place for him to stay the night so he had plenty of time to enjoy Blake's booty.
