When she first reached down, grabbed his dick, played with it and then asked him if she could jerk him off, Matt found himself surprised at what he felt. There was of course the arousal that he felt and that grew exceptionally strong after all that they did together so far but to his surprise there was also a feeling of relief.
Each time when he and his wife had tried to have sex in the past and it didn't work out, the day ended in a soured mood between them and the interest in being close to each other was gone, making it harder to get the desire to be close back with each time that it happened. Emma's reaction now was the complete opposite, she wanted to continue and looked for alternative ways to bring him pleasure. Matt was aware that Emma wanted to be with him and that she didn't want to lose what had just started between them, she made that clear earlier. But he wasn't aware of his own feelings and how much he didn't want to lose that either. Aside from her sexy body and how willingly she offered herself to him did he also enjoy her presence and the conversations that they had. She stimulated him in more ways than just sexually.
So when she looked at him now with those big eyes, asking him if she could pleasure him with her hands instead, it didn't feel like a disappointment to him, quite the opposite. She couldn't know it and he for sure didn't know it either until now but this reaction was exactly the reaction which he needed, it made him feel not only desired but also closer to her.
Leaning down, he kissed her for a long moment as he felt his dick twitch in her hands as if it had a mind on it's own and agreed with everything that just crossed his mind. 'Yes, jerk me off, make me cum with your hands, I want that.'
Laying down on his back, he pulled her with him so that she laid next to him and could position herself however she wanted. 'Show me what you can do with those hands of yours.'
