Round 2 is going to have to wait for a while.

C'mon Ash pick up. I don't know how long i can resist your sister. Brandon thought. Quickly looking over to Hannah who slowly turned back to the desk and quickly looked away before she turned to him. After ringing for a while he got the voicemail, he made sure to listen to the entire message before hanging up. She's not picking up, i'll try again he said to Hannah. Of course babe you can go again anytime she replied whilst leaning forward showing more cleavage to Brandon after having unbuttoned her shirt just a bit further.
Just before he could re-enter Ashley's number a message came back from Ken. Which displayed a small image. He didn't want to look but his curiosity got the best of him and he quickly tapped the message to look. It showed him of a pair of beautiful long brown legs spread looking out over a sunny ocean and what looks like a black haired girl between them licking her center. Wish this was you! with some heart eyed emojis captioning it. He quickly clicked it away and tried to call Ashley again.

Hannah meanwhile was looking at Brandon like a lioness does at her prey. Eyeing him up and down. Noticing that he seemed a bit nervous and anxious. She also saw a bulge forming in his pants and licked her lips at the prospect of having that for herself. She quietly got up and walked up to Brandon.
Not having any luck there big boy? She seductively whispered in his ear after he got the voicemail again. She purposefully leaned into him. Uhm...not really but third time's the charm right? he replied a bit nervously and not looking at her. As he tried again Hannah laid her head on his shoulder and pushed herself against him making sure he was feeling her boobs pressing into him.
Just before it went to voicemail again an angry Ashley answered the phone. What do you want Han?! This better not be one of your stupid pranks again! No wait it's me Bran, babe. Brandon almost shouted fearing what would happen if he didn't get to speak to her. Babe can you ask Heather what the painkillers were that she gave to Kurt? We kinda need to know. No can do she ran off with Zack and I don't know where. Plus I don't want to walk in on those two doing it. I've had enough of walking into rooms where people are doing it. And Ashley started telling what happened but with her role considerably less pronounced.
Hannah meanwhile started to feel up Brandon who became more and more aroused because of the story and what Hannah was doing, pressing herself into his back and feeling his chest and slowly going down towards his dick.
Just let it happen Bran she whispered into his ear as she untangled herself from him and turned him around.
Brandon was shocked as he was turned around and Hannah dropped to her knees. He could see the hunger in her eyes as she looked up to him. It reminded him of the look Ashley sometimes had when they started dating.
Wait Ashley!, this isn't her this is her SISTER shot through his mind, you're on the phone with her, your girlfriend.

WHAT ARE YOU DOING?! He didn't mean to shout but it happened and Ashley stopped talking and Hannah let go of his pants, which dropped to his ankles. What do you mean Bran? I just told you what i'm doing, cooling my arm because Vicky accidentally sat on it. Wait what is happening over there? Get me Hannah on the line.

Hi sis, what's up? She said in her most bubbly voice as she heard the door slam shut as Brandon left.
