Keep the ball rolling

The sheer power and control you felt from getting them both to cum was most likely getting to your head but even with the self-awareness to notice that, you wanted to push on regardless of the problems it might cause in the future.

Emma still clung to your back as she recovered but you didn’t want to give Grace any time to do the same, knowing she was likely to revert back to wanting to be in charge if you let her do as she wanted.

“I want you to turn around and face us” you whispered in Grace’s ear hearing her rough breathing after her climax.

With you straddling her, she didn’t have too much movement but she managed to roll onto her back and look up at you, her eyes widening when she saw Emma still had her hand wrapped around your cock.

“Now, as you can see, your little massage has left me with a problem that I think needs solving so I want to give you some options. Either you can watch Emma finish what she started or you can take her place. And just know that I'm gonna let her watch every single little thing that you do to make me cum” you said, upping the ante when you knew which option she was likely to pick.

Emma took the opportunity to give you a few quick strokes at the mention of her getting you off, Grace’s eyes now drawn down between your legs again. You were quite happy to wait while she made her decision as you now got to stare down at Grace’s tits which you were almost certain you would be getting your hands on sooner rather than later.

“I’ll do it” Grace answered, no anger in her eyes as she choose that option and you could tell she had done this for her own benefit rather than Emma’s.

“Good. Emma’ you can lie down next to your Mom and relax for a while. Just make sure to watch her” you replied, letting Emma move to get a better view of what was about to happen.

Emma almost collapsed onto the bed when she didn’t have you to support her but she lay down next to her mother and you got to compare the two side by side as an unexpected bonus.

Grace had the bigger chest and that wasn’t something Emma would hold against you for admitting. She’d certainly agree with that assessment and it would be a few years before she might catch up with her in that department. With or without the KDK’s help if she were to want that. The rest showed how remarkably similar they were, the height, the toned physique, the wide hips. All showing you that Emma was going to look incredible in the years to come.

You didn’t dwell on the comparison for long as you brought your attention back to solely Grace, her eyes still staring at your crotch as she waited to see what you would do next.

Moving from where you were hovering over her legs, you went towards her, setting over her stomach and letting your cock rest in her cleavage before you grabbed the bottle of her lotion and squirted some onto her tits and your dick.

“Hold out your hands” you commanded, Grace doing as you asked without any complaint.

You put more lotion into the palms of her hands before you discarded the bottle, taking hold of her arms and directing her to start stroking you. She didn’t need much encouragement however as she was soon focusing on stroking you while you moved to continue your ‘massage’.

With her tits now coated, you let yourself reach down and grope her to your heart's content, occasionally looking over to Emma and while she did seem to enjoy watching what you were doing, you did detect a hint of jealousy that she wasn’t in your place. You could only smirk at that as you weren’t going to give up your place now that you had your hands where you wanted them.

You did get a few gasps and moans from Grace when you did something she enjoyed but that wasn’t your main goal, just getting her back into a hornier state until you could up the ante.

“I’ve been dying to do this since I met you” you commented, moving her hands from your dick to the sides of her tits, placing your dick in her cleavage and getting her to apply some pressure on you.

You had lubed her up enough with your groping and you easily slid between them as you moved your hips, getting Grace to do some of the work as she changed the pressure with her hands.

“Of course you wanted this” Grace replied, first looking at you with a smirk before she looked to Emma to comment.

She only seemed to realise the situation she was in once she met Emma’s eye, immediately turning her head away with a look of embarrassment but still not letting go of her tits as you thrust into her cleavage.

“I’m pretty sure I’m not the only one who wanted this either” you replied, reminding her of who was watching again right next to her shoulder to shoulder before you continued.

“And I am restraining myself here. There’s plenty I want to do with you that I’m holding back on. I know we started all this with you teaching me in Emma’s place but I’m sure there’s plenty left for you to teach” you said, not stopping your hips for a second as you fucked her tits.

“...I didn’t know you told her that as well” Grace meekly replied, still not looking in Emma's direction but having enough confidence to stare back up at you.

“Like I said, I’ve told her everything. And I bet you could teach her as well. Like how to perfectly get a guy to cum using your tits” you suggested, seeing Grace visually swallow as her eyeline went back down to your cock between her tits.

You had no idea what was going through her head but you could tell your words had affected her, even if she wasn’t completely sure how to react.

“...I think it’s a good idea…” Emma quietly added, getting Grace to turn in her direction with wide eyes before Emma carried on.

“What?!... You always talk about how I need to be safe even if I was to go out with Max… but anyway, why don’t you show me how it’s done” Emma said, getting nervous about mentioning conversations she had obviously had with Grace before you confessed to her.

Emma did say she had been waiting for you to confess for a while but the fact that she had been talking with Grace about it prior to that did make you raise your eyebrows. You wanted to ask her more about that but seeing if Emma’s addition would sway Grace in one direction or another was what came first at the moment, no longer having the KDK to rely on and just leaving the charisma between you and Emma left to get the job done.
