During the night Larry woke Heather up several times for his pleasure. He felt like a teenager again himself. He couldn't get enough of her and it excited him. He couldn't even feel this way with Linda anymore.
Larry got Heather up to join him for one more round in the shower before he left for work. He left for work more relaxed than he'd been in years. Heather had come downstairs after her Dad had left for work to fix herself some breakfast.
She heard a peck on the kitchen door. She knew before she even opened it that it was Kelly. However seeing Kelly's older brother Keith standing there with her was a surprise.
"Hey girl, how was your night?" Kelly said with a giggle. "We thought we'd come see if you wanted to play in the pool before you have to go to work. Keith is on leave for two weeks and I'm trying to find him things to do."
"Well, I was about to make some breakfast." Heather said. "I guess we can play for a bit." She wondered why the siblings were looking at her like they knew something. "Let me just go change into my swimsuit.
Heather ran upstairs and shut her door behind her. Quickly stripping, she was caught off guard when her door opened and Kelly and Keith walked in. "Kelly, what the fuck? I said I'd be right down." Heather cried out, trying to cover herself.
"Oh, but my dear friend, I'm guessing you don't remember that when we Skyped yesterday, you forgot to turn off your webcam. I watched something very interesting last night. Wow, Daddy sure did love fucking his virgin daughter, didn't he?
That's okay Heather because I've always wanted to play with you. I bet you didn't know that did you? That's okay, because today you're going to play with Keith and myself. I mean I know you don't want that video to get back to your Mom or your Dad's boss, would you?" Kelly giggled.
Kelly took Heather's face into her hands, bringing their mouths together. Kelly kissed her the way she'd always wanted to. Soon their tongue's were dancing together like they'd been doing this for years.
Keith got behind Heather, wrapped his arms around her and cupped her breasts. Kelly pulled away from Heather's mouth as Keith offered Kelly, Heather's breasts. Kelly took one perky nipple into her mouth at a time. Heather moaned.
Together, the siblings got Heather on the bed. Kelly wasted no time sliding her tongue into her friend's already used pussy. She licked, sucked and nibbled her best friend. Kelly was in heaven. In just a few minutes she had Heather screaming her name and clenching the bed sheets.
She brought her face from her best friend's pussy and kissed her brother deeply. "Now Heather, I want you to eat my pussy. Keith is going to fuck you from behind while you do."
