Feed Melanie more cum before heading home

The rest of the beach trip is relatively normal. After your anal adventures, Melanie can't sit comfortably, which means she spends a lot of time lying on her stomach. That leads to you ogling her butt, which in turn leads to her swallowing down a few more thick loads. She fails to see any connection, continuing to lounge with her sore ass in the air.

Besides that, though, it's just a regular, relaxing day full of swimming and tanning. When the sun gets low and it's time to leave, you begin to pack up the car. You've had an amazing time, and it's a bit sad to see it end.

When it comes time to load Hannah in, Melanie puts her in the front seat. You ask her why, and she tells you that she isn't up to sitting down at the moment; instead, she'll lay across the back seat. Her head ends up resting against your lap... And despite spending all day emptying your balls, you begin to get hard once again.

You run a hand through the unwitting MILF's hair. "Mommy, can I get a release?"

"Now?" Melanie seems hesitant. "I mean, I will if you really need it--"

That's all the encouragement you need. You whip your dick out and start masturbating just inches from her mouth, your other hand groping her ass. That causes him some minor discomfort, and she squirms around... With every adjustment causing some part of her face to graze your stiff cock.

The teasing of her soft lips against your cockhead is too much to bear, and soon you announce that you're going to cum.

Melanie seems worried: "How am I supposed to keep it from making a mess?" She tries to get her head between your legs, but the angle doesn't quite work out; her open mouth is still hovering above your crotch. "It's going to drip--"

Ignoring her entirely, you lean back, groan with pleasure, and begin blowing your load. Melanie thinks quickly, leaning down and taking your tip into her mouth. Instead of sucking she just hovers there, her lips grazing the bottom of your cockhead as you shoot ropes of jizz into her mouth. The warmth of her open mouth makes you cum even harder, and soon you're all out of ammunition.

"Everything alright back there?" As Greg turns around, you give him a thumbs-up... And he immediately turns back to the road. Apparently the sight of his wife's lips on his son's cock isn't too out of the ordinary.

Melanie pops back up, managing to swallow your seed with a slight grimace... Well, most of it, anyway. Two white trickles are making their way down from the corners of her lips, and more semen is splattered on your junk. She wasn't exactly making a vacuum-tight seal; maybe next time you should get her to do some actual sucking.

As your weary and cum-dribbling "mother" lies back down to rest, you take a moment to bask in the glory of the new family you've created. Soon you'll be back home, spending the evening doing whatever you want.
