She, seemingly hesitantly at first, placed her hands on his chest; then as if spontaneously gaining courage, pressed firmly until he followed the momentum and laid back, looking up at her.
His body was tense beneath her, as this was an uncharacteristically physical gesture for her, but she ignored this response, and leaned forward to whisper in his ear, "Put your hands in my hair, and pretend that you love me."
Gingerly, he rose a fraction to escape the utterly vulnerable position she had placed him in, both physically, and with her words. He sought her gaze and explored the depths he saw there; the pain, longing to be held, desperation, and something else he couldn't place. Before he had the chance, she averted her eyes, and he was desperate to bring it back. He wrapped his arms tightly around her, and felt her stiffen before relaxing- almost melting into him. Taking one hand, he weaved it into her hair, combing backwards through the strands, gently forcing her to look up at him once more.
They had somehow moved such that she was now straddling him, her thin dress splayed around them, covering what was beneath- a rather impressive erection, and her crotch which was unconsciously grinding against it, sans clothing, since she hadn't bothered to replace her panties after their swim.
Placing both hands in her hair now, seemingly reassured by whatever he saw in her eyes, he gently massaged and brought her closer to his lips, so that she was almost lying on top of him, trying purposefully to ignore the need pulsing through his veins (and other areas) to strip off his jeans and push into her very naked lower half. He stopped himself not because they were at a public beach, because that had never stopped them before, but because she wanted to feel loved.
Probably without the aid of his overeager cock.
So instead, he pressed his lips to hers, trying to convey every real thing he had felt for her since they met, trying to push it into her, to make her feel it, breathe it, live it. She had wanted artificial love from him, to 'pretend', but he couldn't do that. He couldn't love, either, which is why she had added the qualifier to her request, but he wasn't going to give her something false, no matter how much she believed he was right now. He was never duplicitous, even under instruction, and it was both a point of pride with him, and also one of the reasons she was with him. He would never lie to her, and nor she to him.
That's why they worked so well together. Occasionally they would misunderstand each other, become moody, or spiteful, or not know what they even wanted let alone be able to convey it to each other, but they never had any big problems, because they were always on the same page- or at least the same chapter (she was a fast reader).
Focussing entirely on her now, and the weight of her on his lap, that somehow erased any weight the world had placed on his shoulders, at least for the moment, he put all of his reverence and care for her into that kiss. He worshiped her with his hands in her hair, down her back, and with his lips and his tongue. He dreamt of the way she tasted and took the opportunity to indulge in her. He knew the moment would end, and didn't want to let go. Usually, she responded with fevered vigour to match his ardour, but tonight she seemed content to be held safely in his arms, and feel loved by someone, anyone. He was as attuned to her as she was to him, in such a short time, he never knew this kind of connection was possible for him.
