They are sitting together.

You look across the living room to see Tracy and your wife sitting close to each other. Tracy has her arm around your wife and is slowly stroking her hair. You look past them to the TV and see 2 girls on the screen in the 69 position.

"Damn," you think, "how long has this been going on between them?"

Looking back to the sofa, you see Tracy lean over and kiss your wife gently on the cheek. Your wife then turns to her and passionately kisses her.

Glancing back at the screen, you see one the blonde putting on a strap-on while the brunette gets on her hands and knees. The blonde then starts to slowly work the dildo in and out of the other girls mouth while she bobs her head back and forth to meet the blonde's thrusts.

You reach down and start to rub your throbbing cock through your jeans. You are so hard you feel like you are going to rip right through them.
