"Enjoying the show, honey?" Heather giggles. "Simon set me a copy of that video, too. Not to mention the other videos..."

"You didn't expect him to stay a virgin forever, did you?" She teases.
"Yeah, Katie is a real sweetheart, isn't she?" Simon grins. "She started coming to our parties when it turned out her old white boyfriend was a dud in the sack."
"Gee, doesn't that sound familiar?" Heather wonders aloud sarcastically. "Like father, like son."

Your wife leaves you alone with the computer as she and Simon go to the bedroom. You shut the computer and try to forget what you just saw. A few hours later, Simon is done pounding your wife's pussy and goes home. Heather then generously slurps up your small dick in her mouth, easily coaxing you to cum.

Downstairs, you hear Connor come in through the front door.
