She goes above and beyond the request

The next day, you wait what feels like an eternity for your mom to come home from work. Your dad's not home until very late that day, so you're eager for another round with your mom after she brings you the footage you've demanded.

To your annoyance, she's far later than normal, leaving you with no recourse for the throbbing erection you've gained thinking about what you'll be doing soon.

You end up stroking to your videos of your mom with Mr. Thicke while you wait, holding back from cumming only with a great exercise of self control.

Finally, more than three hours late, your mom staggers into the house, looking disheveled and reeking of sex.

Your annoyance at her being late is tempered by your arousal at seeing her flushed face and disordered clothes; the slutty appearance she gives off makes your dick throb.

You try to sound stern anyway to keep up your advantage over her. "What took you so long?"

Your mom wordlessly presents you with the video recorder. Taking it, you check for your blowjob scene only to see a thumbnail of your mom, naked, on her knees in front of a still-fully-dressed Mr. Thicke.

The sight makes your cock throb, but the duration displayed in the corner of the thumbnail is what really catches your eye: 3:02:53. You swallow, looking at your mom's disheveled appear and putting two-and-two together.

You're pretty sure this isn't a clip of "your mom giving a blowjob to Mr. Thicke". This is a full length video of "your mom and Mr. Thicke rutting like animals for three hours".

"I suggested a filmed blowjob...but he insisted any homemade porn *he* was in would start with his pants on and end with his balls empty..." Your mom still sounds a bit dazed; unsurprisingly so after three hours entertaining a 17 inch cock.
