Gwen strides into the Hub intent upon making Jack 'see reason'. She opens his office door to see…something she would have really rather not seen. But that bell can't be unrung.
Flinging open the office door (in hind sight, perhaps there was a good reason it was closed after hours) Gwen stops abruptly, her mouth doing the fish impression. She sees Ianto splayed across Jack's desk with his head thrown back and his eyes clamped shut in ecstasy, while Jack's hands have a firm grip of Ianto's hips. She sees this while her ears are filled with the sounds of lovemaking: moans, gasps, and shuddering sighs mix with the sound of flesh hitting flesh.
Jack's face is set in lines of extreme pleasure and concentration, mixed with a bit of effort as his pelvis moves like a piston against the backs of Ianto's thighs. Ianto's fingers are wrapped tightly around the edge of the desk to provide additional leverage against Jack's thrusting hips; Ianto's eyes snap open during a particularly pleasurable thrust. His hands switch from the desk to Jack's forearms as he stares into his lover's eyes, while Jack grasps Ianto's cock and starts stroking it in time with his thrusts, eliciting a choked whimper from the man under him.
Additional trembling and shuddering indicate to the lovers that the peak is near, and they redouble their efforts. Ianto reaches it first, with a scream of Jack's name followed by a long shuddering moan as he feels Jack follow him over the edge. Adding his own shouted name to the noises already present, Jack shudders his way through his own orgasm before sliding down to the floor limply. He takes Ianto with him, and they start to cuddle as their heartbeats settle into a more normal rhythm.
Having seen quite enough, Gwen fled back through the open door amidst the shouts of completion. She retreats to the garage door to try and regain her equilibrium before attempting to drive back home.
Ianto lazily opens his eyes and looks blearily at his lover; his eyes close and then snap open again when he sees the open door. "Jack? Didn't we close that?"
Jack opens his own eyes and looks in the same direction. "Yeah, we did." Jack leers a bit before going on. "I wonder who wandered in and saw us this time?"
Ianto carefully extracts himself from Jack's lap and walks on wobbly legs to the closest station to check the CCTV; "It was Gwen, and she's still here." Raising his eyebrows in amusement, he continues on, "She looks quite gobsmacked; one might even say she looks green." Jack rests his chin upon Ianto's shoulder while he watches the footage.
"Wonder what she wanted?"
"Who knows, if it is truly important, she'll be back; otherwise, let's get some Thai, had quite a workout!"
Jack preens as he nuzzled Ianto's neck chuckling. "Thai it is, and then we can move on to the next round…maybe some naked hide and seek?" Jack directs the biggest puppy dog eyes he can manage at his lover.
Ianto snorts at the display and reaches for his mobile to call in their order. He and Jack don their clothing and walk hand in hand to pick up their dinner before making their way back to the Hub.
Gwen, having regained her composure, hurries to her car and returns home. The morning should be a bit easier to see Jack alone, at least then Ianto is likely to be in the archives.
