Teaching two shy twin sisters

As you walk out of your last class, you see two cute girls waiting for you. You've never met them before, and both of them are very petite and wearing pink dresses and skirts. They look almost identical, and you suspect they must be twins.

When they see you, they both blush nervously but step a little closer to you.

"Hey girls," you say smiling at them, wondering what they're interested in and why they're so nervous.

"Hey... I'm Ella and this is my sister Emma," one of them says looking down slightly. "What's your name?"

"I'm Nathan, nice to meet you both," you say. "How are you?" They look even more nervous now, making them even cuter, and you can't resist checking them out a little.

"We're doing okay, thanks," Emma says quietly. "Do you maybe want to come to our house to study with us?"

"Of course, why not," you say, surprised but happy to hang out with such hot sisters. They look relieved, and it seems like they were worried about you rejecting them. You can't imagine why you would though.

"Thanks Nathan," Ella says, both of them super excited. "You can walk home with us!" You hold both their hands softly, and they giggle shyly but smile.

"I'm definitely gonna have to have some fun with these girls," you think to yourself, and you wonder if that's what they're actually looking for.
