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?
