Sarah lay in her bed, staring at the ceiling for over an hour after Gideon left. The sex hadn't been completely horrible, but she was definitely still on edge. Earlier when she had seen Gideon in the kitchen door through half closed eyes she had thought that being with him would be more like being with, well, like being with Seth, sweet and gentle, loving. But her brother and her father were two very different people. She rubbed her wrists, still a little sore from being held so tightly and felt a tingle of arousal low in her belly. She slipped from bed and into her bathroom, cleaning up from Gideon, then pulled her pajamas off and slipped into a robe before quietly creeping down to her father's room. She entered silently and removed the robe at the foot of the bed before sliding in next to her father, completely naked. He awoke instantly and pulled her close, kissing her for a moment.
"Sarah, baby girl, you know we can't."
"Gideon knows, Daddy. He saw us in the kitchen. He was shocked and left pretty fast." She took a deep breath. "Then I let him know that I knew he was there before we went to bed, and he got a little drunk and came to my room. I'm sorry, Daddy."
Seth cuddled her for a while, stroking the smooth skin of her upper arm. "Was it good?"
"He wasn't really thinking, Daddy. It was a little rough, and well, I'm still kind of horny. Please, Daddy?"
Seth slipped a hand between her legs to play with her clit while she pressed her body tighter to his. "You never did really answer my question, baby."
"It was different. He wasn't as sweet as you are."
"I'm sure it was a shock to him, Sarah. And he didn't have all of the fantasies I've had about you over the years." Seth continued to play with her clit, watching her face for the signs that she was nearing orgasm. When she was on the brink he stopped and kissed her forehead. "Go to him, baby girl. Ask him to take care of you properly this time, and leave the door cracked. I want to peek in on you. Maybe I'm just a perverted old man, but the thought of seeing you with someone else is exciting to me."
"I love you, Daddy," she whispered before kissing him deeply.
"I love you, too. Now go seduce your brother."
Reluctantly slipping out of bed, she gathered up her robe and slipped it on, then crept back down the hall to Gideon's room. She opened the door as quietly as possible, and left it ajar behind her so Seth would be able to watch. Her robe came off again, but this time she left it in the floor and walked silently to her brother's bed. He was laying on his back, and she thought maybe he was still awake. When she tripped on one of his shoes and stumbled, falling against the edge of his bed, he popped up, his chest bare and eyes bleary and unfocused.
"Sarah, what's wrong?"
"I'm naked in your bedroom, Gideon, what do you think is wrong? I'm still really horny. Maybe you can't keep a girlfriend because you aren't that great of a lover." She squeaked as he grabbed her arm and pulled her towards him, rolling quickly to pin her lush body beneath his.
