Exhibitionist fun

“Could she really be watching?” Grace asked, the arousal in her voice coming through a lot heavier than any sort of fear about getting caught.

“There's always a chance right? What if she’s stood right outside the door watching us. We wouldn’t hear the door opening over the shower and she could even be stood in the room with us” you replied, feeling Grace shiver behind you at your description.

You knew the temptation to turn around would win over Grace sp before she could do anything about it, you turned around yourself, letting her hand fall away from your cock while you made sure she couldn’t look behind her.

“You can’t look'' you said, placing Grace’s hand back around your shaft and seeing her look surprised at your move.

In addition to your quick turnaround, you placed her hand on her hips, and urged her to turn with you in the shower, the two of you now standing with the Glass window directly behind Grace, only letting her see the tiled wall behind you while also giving Emma a side-on view.

If you hadn’t moved, Emma would have had no view of the action going on and there was still a chance Grace would look to the side to try and confirm if you were actually being watched.

Now you were in a position to stop her even if she tried but you couldn’t help but smile at the fact that Emma had been here the whole time anyway, a fact that would both scare and excite Grace in equal measure.

This was the first time you had seen Grace fully nude as well and even though you couldn’t glimpse at most of her lower half with you both being cramped together, you loved what you could actually see so far. That glances you had gotten at her breasts so far were nothing in comparison to seeing them in their full glory. You almost certainly wanted to touch her more and your hands almost instinctively reached up to fondle her but you felt that Grace wasn’t quite ready, quickly thinking of the next step you could make to achieve that goal.

“Emma could be right behind you right now and you would never know. I wonder what she would say if she saw us like this?” you asked, stealthily signalling to Emma without Grace noticing.

“Kiss her again! I want to watch this time” Emma revealed, only having seen the two of you through her dream earlier and giving you something to suggest to Grace.

“Do you think she’s gonna be excited as I am right now? If she’s actually here and she hasn’t revealed herself then maybe she actually wants to watch us. Maybe she even watched us while we were downstairs. Do you think we should pick up from before and show her the practice we’ve been working on?” you continued to ask, not getting a response but feeling her speed up the handjob.

Grace’s temptation seemed to win as she went to turn her head, making you quickly move your hand to cup her chin, with her staring straight into your eyes as you took the chance you were given. You brought your lips towards hers and pulled Grace in for a kiss, feeling her instantly respond as soon as you touched.

All thoughts about turning to look had left her mind as the two of you made out, your tongue intertwining with hers just like earlier, except this time she now had her hand pumping up and down your cock without any hint of stopping. Even your thoughts were momentarily put on hold as the kiss continued, almost forgetting that Emma was still watching as your hands finally moved towards Grace’s chest.

Your fingers grasped her tits like you had always fantasised about, only stopping when Grace pulled back slightly to stop the kiss, forcing you to come up with a response before you could luxuriate in what you were feeling.

“Don’t you think we should put on a show if she is watching? If she has been standing right behind you all this time then surely she would have spoken up if she didn’t like what she was seeing. Maybe she just wants to watch and see what her mother gets up to when she isn’t usually there to see” you teased, watching as Grace closed her eyes to try and calm herself.

The fact that her hand became more energetic on your cock showed that her plan clearly wasn’t working, forcing her to fantasise about what Emma could be doing instead of looking at you. She quickly changed her mind and stared straight back at you again, the lust evident from just a small glance.

“We really shouldn’t be thinking about this” Grace whimpered, not condemning any of your actions so far but just her own thoughts about bringing up Emma.

“Why not? What the harm in a fantasy or two as long as both of us are enjoying it?” you responded, moving your head forward to kiss her once again.

Grace once again surrendered under your control and this time she didn’t stop you from fondling her, even letting out a moan against your lips when your fingers brushed against one of her nipples. Just getting this far with her had been a dream come true and you could feel yourself getting close under the constant pleasure that Grace’s hand was giving you.

It also sounded like you weren’t the only one as you could hear Emma off to your side start to get increasingly loud. You knew you would normally feel guilty about ignoring her when she was only a few feet away but Grace had managed to take all of your attention ever since you had gotten the upper hand over her.

You couldn’t see her from where you were standing but just knowing that she was pleasuring herself was enough to rush towards a climax, forcing you to pull your head back to tell Grace.

“I’m gonna cum soon” you warned, making sure Grace knew what was about to happen.

“Let it all out for me” Grace encouraged, her hand never slowing at the news as she continued to jerk you off.

With the sounds of Emma’s moans filling the room and Grace urging you to cum, you finally gave in and let yourself orgasm, your climax rising as your first ropes of cum arched and splattered against Grace’s stomach, dripping down and leaving her covered from the waist down.

Emma must have seen the sight and pushed herself to her own release, her moans suddenly getting quiet as the pleasure took over her, still not able to see her fingers moving furiously between her legs to reach higher and higher states of bliss.

Grace on the other hand continued to coax the rest of your cum out of you, the less powerful spurts falling into her hand and coating it completely. Her hand slowed when you had nothing else left to give her, all three of you letting out heavy breaths as the situation had passed its peak.

The sounds of breathing and the spray of the shower filled the room, both you and Grace finding it hard to speak up next.

“That was amazing” Emma’s voice admitted down at the side of you, presumably having lowered herself on the wall during everything that had happened.

Her voice made it easier for you to speak up yourself but it seemed that you were a second too late as Grace opened her mouth to speak.
