Taking in the situation

Before either of them spoke, Emma made sure her line of sight never strayed from her mother to make sure she didn’t miss anything, but Grace didn’t have the same thought.

With her looking around at the current state of the car, Emma on her knees with your dick pressed against her face, her looking askew with her top bunched up to her waist and her hands dangerously close to touching your cock and also Emma in the process, it seemed the entire situation made her reconsider how she was reacting.

With a sigh, she was the one to break the silence that had formed with you awkwardly stuck in the middle.

“Look, I don’t mean to be harsh on you two but I shouldn’t have to worry about you sneaking off every time my back is turned or you doing something like this when I give you a moment to be alone together” Grace said, starting with a more authoritative tone and relaxing more as she went on.

“And I know the both of you will try and turn it back on me as well. I’m not blind to Max’s stares. I’ve been used to men looking at me for years but I’ve been catching yours as well Emma. Don’t think I didn’t see you in the changing room before” Grace continued, you realising how she must have seen Emma earlier when she was letting you get a look at her with the beholder effect.

“So the point of me saying all this… I think you don’t mind my presence and from what you have told me you might enjoy it so I think I’ll be a little less restrictive on what the two of you can do together while I’m with you. I’d rather you do it where I know you aren’t getting into trouble.” Grace explained, the argument she was making usually being made about **** and drinking rather than blowjobs and sex.

Due to how your hands were positioned, you could faintly feel her heartbeat and she was definitely still being affected by the kiss earlier to suggest something like this, her heartbeat not at a resting level but not fully racing as her suggestion most likely catered to some of her own desires as well as your own.

“Any questions?” Grace finished off with, looking at both of you in turn and forcing Emma to take her mouth away from your dick in order to reply.

“Why? I mean I think this is great but your phrasing it like this is all for our benefit and you aren’t enjoying all this as well” Emma queried, knowing Grace’s feelings even without having to rely on her heartbeat like you currently were.

You still got to see that Grace was continuing to act composed but her body was betraying how she looked. She did take a few seconds longer than you would have thought to say her answer which seemed to give Emma another hint as well.

“I-I’m just okay with this that’s all. See I knew you would try to spin it on me” Grace replied, the shaky start not helping her out.

“Alright, prove it” Emma said, not believing her mom for a second.

“What do you…” Grace started to reply before Emma cut her off.

“Max, check how wet she is” Emma suggested, going straight to you instead of asking Grace to prove it herself.

“I-I don’t think that’s really necessary” Grace replied, now fully on the defensive but still not making any move to remove herself from your hands in order to stop you.

“Why not? You said you weren’t doing this for you right, so you shouldn’t have any issue with him checking” Emma said, adding more to her argument and even starting to work her hand up and down your cock as she got more interested.

It seemed that there were certain times where Emma got the urge to be more dominant when you were with other subjects but she never seemed to be that way with you, always defaulting to a more submissive role with you. You didn’t want to dwell too deeply on it in the current situation but the word ‘switch’ came to the forefront of your mind.

Before Grace said anything else in her flimsy defence, you brought a hand from where it rested below her chest and slowly traced your fingers down to the waist of her jeans and then into her underwear.

She made no attempt to stop you and even parted her legs as you did so and the evidence was quickly made apparent when she let out an intake of breath and your fingers felt the dampness of her crotch.

“It’s just because Max has his dick out…” Grace said as the only excuse she had left, letting Emma know the result before you even had to tell her.

“And was the same when you watched Mary go down on him in the taxi? From what I heard you seemed to enjoy Max’s fingers that night as well” Emma questioned but no further reply came out of Grace for the moment.

The role reversal was something you would have never expected between the two of them but as Emma continued to keep stroking you, you felt your confidence increase and you knew you had to join in with making Grace get more involved with the experience.

Last night had been all about just you and her with minimal contact with Emma but in the current state she was in, it felt like now was the perfect time to try and push them boundaries.

“You did seem to be looking at the both of us a lot while we were sat back there. Maybe there was some enjoyment on your part. There’s no shame in admitting it…” you started to explain, taking your other hand to guide one of Grace’s towards your cock, it having already been resting in your lap but now you wanted her to join in with Emma, placing her hand over Emma’s so the same rhythm was kept.

“...there's no harm in it either. Sometimes we just need to let other people show us what we truly want to do. What you truly want to do” you added, letting go of her hand and having her continue her stroking alongside Emma.

Emma’s hand was the only one still touching your cock but you didn’t care about that at the moment, just looking down at what you had got the both of them to do together was already enough for you to consider this a huge step forward.

With a hand free, you moved it down to the other side of you where you could just about touch Emma’s arm, giving her a small pat as if to acknowledge what was happening while your other hand now started to move inside Grace’s panties. Grace let out a light moan of pleasure in your ear as your fingers dipped inside her and while you had hoped that would also catch Emma’s attention, it seemed something else had come to her mind.
