He struggles to keep his usual cool

Felicity has a moment of panic as she realises Grace has somehow got her outside into the store, feeling even more exposed in this lingerie than she felt when she was half undressed earlier. She takes a quick look around, convinced that the store will be full of people suddenly, all now staring at her body that is very much on display. She let’s out an internal sigh of relief in finding that no one except him is still there.

He looks up from his phone and in her direction, and Felicity is excited to see a look cross his face that is so unlike the usual casualness he has displayed so much since they first met. Instead there is a brief moment when that veneer he uses to hide his lust disappears, and she sees his surprise and delight at what he is seeing.

“Well, I wasn’t expecting quite such a daring look” he calls over from his seat as he regains his composure. “Turn around young lady” he adds after a moment of looking at her. She obliges happily, slowly turning to allow him to see the view from behind, knowing how naked her ass will be looking with the thong almost disappearing between her cheeks. “Amazing” she hears his further approval as she stands facing away from him.

She stands motionless, still with her back to him, suddenly unsure what she should do now. Wondering if he has finished his appraisal and expects her to go back into the changing room, or whether he is still looking at her, and she hopes imagining fucking her in her new lingerie.

Her heart beats fast in her chest as she waits for some indication of what she should do. It feels like minutes as she stands there, until suddenly there’s a finger running slowly down the bare skin of her back, downwards until it slides over the wafer-thin waistband of her thong, and lower, over the curve of her soft ass. She shivers in delight at the touch, suddenly not caring she is so on display.

She looks up to see Grace standing at the changing room doorway, watching her, watching over her shoulder to the person behind her, touching her, a smile of pleasure on Grace’s face as she admires the results of her lingerie choice for this young girl.
