"Don't want to..." what she did or did not want briefly became a lost thought that simply could not be focused on properly when he had his lips on her throat. Her breath became lost too, out the window with all coherent thoughts. She hadn't ever been kissed on quite like this, never snogged a boy until she was sitting pretty on his lap.
"..go back," she finally recalled the rest of her thought and breathed it out slow, then her whole chest rising and falling with the quickening breaths. Her arms snaked about his shoulders then bent at the elbows as her chin tilted backward.
Those thighs tightened for a moment and then she shifted until she could stretch her legs out on either side, so if he leaned her back it'd be only to easy to give him all kinds of access to her body. Suddenly she felt very nervous and could hardly understand it. She certainly wanted this.. but what scared her was how much she wanted it.
