Brad celebrates New Years alone and depressed in his room until he receives an unexpected visitor after midnight.Excerpt; "Why aren't you sleeping already? You look exhausted" he asked, as she propped her cheek on her hand, pancaking her fine features slightly as she settled in and made herself comfortable beside him. Catching a glimpse of completely inappropriate cleavage as she shifted, Brad tried to ignore the smell of strawberry shampoo that accompanied his freshly scrubbed sister out of the shower. "I miss my old bed" she said with a sigh, bouncing lightly on the old, tortured springs of Brad's inherited mattress. "You have a new one though!" he exclaimed, mildly indignant. Their parents, currently away in a neighbouring city celebrating New Years with friends, had only had enough money at Christmas to buy one of them a bed. Big surprise, his sister had gotten what she wanted. Kristine always seemed to get what she wanted. She shrugged. Typical."How was the bar?" he asked, trying to decide whether to shut down the laptop or not. He didn't want to move the device and reveal the half-mast he had downsized to and the damp spot on the front of his boxers he could feel was there. On the other hand, he also didn't want to boil his balls. He was stuck. He could only hope his sister would leave and soon. She giggled as she rolled onto her back and closed her eyes, enjoying the spin of the world behind her eyes. "You know, the usual. Boy bought me drinks. I danced with my girlfriends. Boy bought me more drinks, so I danced with the boy. Boy wanted to take me home, and my friends dragged me away before I did something stupid" she said, giggling cheerfully. Brad glanced at her, running his eyes over her long, athletic legs, and her attractive features. She was lean and flexible, but curvy as well. Objectively beautiful, as he had once put it in the past. She also spent many hours in the sun and in the water. The nearly uniform tan covering her body explained this. "Why didn't you go home with him?" Brad asked, trying to sound bored and uninterested. "Don't you ever get tired of just sex?" Kristine asked in return. Brad was silent as he considered the question. "No. God no" he said, finally. Kristine made a face as her eyes popped open, looking at him once more. "Yeah, me neither" she admitted. "Getting tossed aside like a used sock gets old pretty fast though", she continued, draping a forearm over her eyes.......her pelvis automatically following his as she followed back him down to the mattress, pressing firmly all the while. He could feel his erection throbbing with confused satisfaction as it was sandwiched between their warm bodies. They watched each other, both breathing hard and looking for some sort of indication for what had just happened. Their panting was the only sound breaking the delicate silence.Finally, without real thought to the consequences, Brad gently moved his hips against his sister's warmth, and his heart raced as she subtly pulsed back against him. He repeated the gesture, a little harder, and was rewarded with a similarly harder reaction. The mattress squeaked as they moved, and he chanced a quick glance down to where Kristine's mound was now wrapped around the straining material of his underwear. They rocked together again and again, with newfound and sudden urgency. He became painfully aware of the squeaking sound of the bed as their hips continued rolling and grinding together. Her soft sighs perked his ears, and the growing wetness between them made the thin material of his boxers a transparent, clinging affair.
