My lover's lover

I walk into the house, and it's oddly quiet. There are two other people here, but I can't see them, can't hear them. 

Slowly, I wander the rooms of my home... my sneakered feet are quiet on the hardwood as I wonder what I will find when I find them.

The guest bedroom is empty, the same with the main bedroom, the media room... until I wander into the kitchen.

He is pressing her into the refrigerator, his pants down and pressed against her while she writhes and moans. Her hands are locked above her head in one of his fists while the other delves into her moist cunt and he is making low, pleased sounds at her response.

The line of his body, pressed against her, is beautiful and I go to them, pressing my suddenly painfully overdressedboday into his. I can taste the slick salt of his sweat and arousal as I press my mouth into the curve of his back. 

My lover is beautiful right now, as he plays with this girl we've both come to care for.
