Tease her some more

The build up to getting to this point and leaving her on the edge felt so tantalising that you wanted to get her feeling even more aroused, knowing that it was only going to prolong that feeling she had only experienced on that night in college so far.

“Do you think you’re ready? I bet all those people out there can see you and are waiting. With a body like yours, there’s no doubt that they want me to move my hands and leave you standing here, no dress, no underwear, nothing. I bet Emma wants to see as well. Knowing her mother is getting wet from exposing yourself like this. So…” you teased, hyping it up the moment for her just that bit longer.

You still let time pass just for a moment longer than she expected before quickly moving your arm away from her chest and raising your other hand up away from her pussy to rest against her stomach, keeping a hold of her with her ass still firmly pressed against your erection.

Grace let in a sharp intake of air as you showed her off in front of the window and she could clearly see herself in the reflection, seeing for herself what she was currently showing to anyone who happened to be looking up at the window.

“Fuck…fuck” you heard her whisper, her ass moving against you as she squirmed.

The mix of your control over her and the actual pleasure she was giving to you unknowingly by her movement only made you want more. For a brief moment you considered risking it all to fuck her but you stopping thinking about that before it became too tempting, knowing it would affect your relationship with Grace if she wasn’t ready to take that step.

Instead, you pushed your hips back and aimed your cock lower, pushing between her thighs and feeling again how wet she was as your shaft slid against her.

“We can’t…” Grace whimpered, thinking you were going further but doing nothing to stop you.

“I know, I’m not gonna push inside. Look down and see. Just like this…” you explained, slowly bringing your hips back before pushing forward again.

You could see in the reflection Grace looking down and the tip of your dick pushing through between her thighs, a breath of relief coming from Grace before she pushed her legs together to squeeze you tighter.

Before you got too into it, even if your lust was reaching its peak, you looked over your shoulder to check on Emma.

She hadn’t wasted any time and she lying on the bed with her hand between her legs, fucking herself with her fingers as she watched you and her mother in front of the window.

“Emma” you said, making both her and Grace freeze.

Emma seemed to think she had been caught masturbating when you hadn’t given her orders but you didn’t care about that at the moment. Grace seemed to lock up as she realised that the thought of people watching her had at least one real person in the room to see how she was acting, one much closer and much more familiar.

“Crawl over between Grace’s legs” you directed, making sure she wasn’t seen from the window if she didn’t want to be.

With some extra directions, you got Emma to sit with her back against the wall, staring up at Grace from below and giving her a great view of you fucking her thighs. You didn’t even need to tell her to start fingering herself again but to keep her involved and make sure Grace knew she was being watched, you made sure her presence was noticed.

“How many people do you think are watching us Emma?” you asked, continuing to remind Grace of her exposure.

“I bet dozens. I’m surprised there's not a crowd down there. With how you look, I bet they all think she’s about to get fucked right in front of the window” Emma commented, knowing just what to say.

With that, you started moving your hips again, holding Grace as close to you as you could for a second longer before you pulled back, letting her see your dick poking out between her thighs with Emma sitting below.

Grace was wet and with her thighs slick with her excitement, you could easily start pretend fucking her, gliding between her legs and feeling her ass hit you every time you thrust against her. You didn't need to hide her tits from view anymore so you held onto her hips as you pushed against her, the slapping sound definitely sounding like fucking if anyone was to listen in outside your room.

“Is… there anything you’d like to say to the people watching you down there?” you asked, acting like you were sure there was someone watching.

“I…I…oh fuck I can’t think straight” Grace admitted, now pushing her ass back into you to meet your thrusts.

You continued your thigh fucking with whispers into Grace’s ear, telling her about all the people watching and how they were all looking at her. Even looking at her in the reflection you could tell she was losing it, moving her arms from playing with her tits to go down to start playing with her clit.

Before she could, you took hold of her arms and held them behind her, using them instead of her hips to give you leverage as you started to fuck her harder.

You were sure Grace had cum at least once as she shivered against you and clamped down on your cock, her wetness only letting you fuck her harder. Her moaning was only getting louder and you could tell she was ramping up to something big just as the pleasure was starting to get to you.

You wanted to carry on forever but even you had your limits even with your upgrades.

“I’m gonna come soon” you said, warning either one of them.

“Fuck me too” Grace revealed, the only words passing through your head were her ‘fuck me’ and that seemed to be all you needed.

“Paint me, cum all over me!” you heard Emma say from under Grace, no longer having to worry about where you were going to cum.

You couldn’t see her from around Grace but you didn’t care at the moment, giving Grace a few extra strong thrusts before holding her against you when you felt your climax rush through you.

The both of you seemed to only stay standing as you held each other but you felt Grace quiver as the aftershocks of her own orgasm kept her pleasure spiking.

You felt yourself recover even with your dick staying hard between Grace’s legs, your hidden ability apparently already having recharged since the blowjob downstairs and with some heavy breathes, you held yourself closer to Grace while turning the both of you, aiming to get a better look at what you had done to Emma.
