You're a good boy

It's so tempting.

So, so tempting, as Sophie fits her body to you. So soft and warm and you have that lovely image of her: tiny, slim and sexy and toned.

Just the thought makes your hard cock throb in her hand as she cups your balls. It is so tempting to roll her onto her back and slip your dick inside her. Thoughts of fucking her in her sleep make your cock twitch again.

But no, you sigh, looking at your sleeping wife: it is wrong for her, Emma, and also for Sophie. So you ease away gently so as not to wake her, reluctantly moving her little hand away from your balls.

You're so hard you ponder having a wank in the bathroom, but decide to settle down and try to sleep despite your thudding heartbeat.

You hear a very soft sigh and notice that Sophie is now cuddling up to Emma. You smile. Sweet, the way she moulds herself to your wife, her hand moving down Emma's body, pulling them gently together.

Emma seems to respond, reaching out to touch Sophie's wrist, and you watch as the two sleepy girls nonchalantly embrace before you. Before long, legs are entwined and the two have become one. Sophie murmurs and moves against Emma in her sleep, gentle sinuous rubbing of her sex against your wife that you find very exciting: you are rock hard again.

This continues for a while. Slow and comforting for Sophie but very sexy for you to watch. Then you see Emma's hands move, starting to stroke Sophie's body at first, then urging her to move. It looks like they are both still asleep but she is now pulling Sophie to her and soon Sophie is atop her, nestled between her legs, as Emma hugs her tight and strokes up and down her body. Cupping that perfect little round bottom that you yourself covet.

You're captivated. You've often wondered about the two of them and now you are seeing it unfold before you. As if on command, Sophie moves her sex to Emma's and, making contact, starts to move gently against her, making love to her. This goes on for a few minutes, then her hand moves down between them and Sophie touches Emma's pussy. Emma arches and gasps under her breath but moves against the hand. It's hard to believe they are not awake now but they are oblivious to you if they are.

Sophie's fingers explore Emma. You can't see but judging by the reaction they are deep inside her as Emma moves rhythmically against them. Sophie kisses Emma's neck as she responds, her other hand stroking her breasts, then she moves her mouth to cover hers and kisses her full on her lips, the whole time her fingers (her hand?) moving in and out, speeding up but still loving and gentle as your wife responds and moves with her.

Emma's breathing is distinctly faster now and Sophie is matching her finger movements to her kissing but also moving her own hips to Emma, her tempting little bottom moving up and down rhythmically. Making love to your wife before you, Emma's back arched, her eyes closed, her mouth open when it's not being kissed, and she's speeding up, pushing onto Sophie's fingers.

You know Emma. She is close to orgasm.
