Your sister

...your sister is standing behind you.

"Well, this is lovely dovely." she said in a suspicious tone.

"Oh, h...heyyy sis, didn't see you there..." you respond with your whole body stresses out and begins to shaking.

"Babe, I didn't realize you have a cute sister." your teenage mom replied.

"Oh he didn't tell you about me?" you sister asked as she's pointing at you.

"Well, no... but I think he's too embarrassed to talk about you." your teenage mom answered.

"Yeah, I guess you're right, plus he didn't tell me about you either, I guess he's such a pussy to tell me about his beautiful girlfriend." your sister replied as your former mom and your sister laughed as they tease you. "But come to think of it, you look familiar. Have we met before?"

"I guess so..." your teenage mom replied.

As they both look at each other closer, you've been thinking if your sister finds out about her, she might be freaked out and scream. "Hey, sis. I've been thinking me and my 'girlfriend' here is about going to the date, if you're free would you wanna come with us?" you asked your sister to come with you as you realize you mess up.

"Okay, sure why not? And beside, I just wanted to know about your girlfriend, she seems quite interesting. " your sister replied as your teenage mom's happily smiles.

"That's great, babe. I also want to getting to know her too." your mom said as she and your sister both are holding hands. "I just hope we're going to be a bestie."

With that, you and both girls are hoping 'your car' and drive off. After that...
