The sex was violent. The sex was always violent; thrusting, pounding, pulsing desire running through them both as nine full inches of cock was forced into a hole far too small for it.
Things were better now than they were. No more petty resistance, no more snippy remarks...Kate had finally come to, and Sheldon was not entirely convinced that he hadn't gone mad and started dreaming shit up. Kate's moans in his ear, her whispered words, gave Sheldon all the motivation he needed to fill her with every ounce of come he could produce before collapsing on her chest.
They panted together, for a moment, Kate's fingers drawing little circles on his shoulders, and occasionally trying to move his hair out of both their faces. She kissed his cheek gently- a far cry from the vicious bite she'd given his shoulder when she'd come - and sighed.
"I'm fucking dreaming. I've just gone insane, and I am actually in some padded cell somewhere, humping the floor and making a mess in my hospital gown, aren't I?" he breathed, trying to calm his racing heart. His sister chuckled beneath him and ran her tongue along his neck and nipped him gently. Sheldon sighed, smiling.
"Hey, hey there," he said, softly, pulling away to look at the woman beneath him, "Don't. You'll get me all excited again, and god dammit my cock is exhausted."
Kate smiled and apologised sorrowlessly, kissing Sheldon firmly on the mouth before letting him pull out of her and lie beside her on the bed. She turned on her side to press her naked body against his, her breasts brushing distractingly against his shoulder as she made to kiss his cheek.
"I love you."
That was the only bothersome part. It wasn't that Sheldon particularly minded hearing it, anymore. He actually enjoyed it, truthfully, and not just for egotistical reasons. It was the closest thing to feeling he got, really. What bothered him was feeling obligated to say it back. Society says that in a healthy relationship, one person does not say "I love you" and have it go unreturned. It was required.
Of course...society also said that in a healthy relationship, a brother and sister do not willingly fuck like rabbits in a Viagra testing laboratory. And Kate insisted that she didn't need, or even necessarily want him to say it. She just needed to say it, herself. So, all right. So long as nothing was expected of him (except, perhaps, a constant erection), he could deal.
She was stroking his stomach, he realised when he'd resurfaced from his deeper thoughts, and getting dangerously close to what teenage girls liked to refer to as his "treasure trail;" the line of dark, thick hair leading down to his pubis. He smacked her hand away, flattered but tired.
"I mean it, Kate. I'm fucking wiped out," he said with regret. He couldn't help but be amused, however...he hardly thought that one day, he would be pushing his reluctant, prudish sister's hand away from his crotch because he'd come too many times that night.
"All right, all right," she conceding with half a resigned smile. She kissed his shoulder in a disgustingly endearing way, draped her arm over Sheldon's chest, and relaxed, eyes shut. Shel allowed himself a vague smile as he, too, allowed sleep to creep up on him.
