The passionate, peeking parent was sliding her own tongue around in envious emulation.

Frostie let Chuck tit-fuck her for a while, then ducked down and began to tongue his balls. She laved all over them with her tongue, purring with pleasure.

She could feel his heavy cum-load sliding around inside the gamy bags. She sucked gently, absorbing the nutty goodness of his cumbags.

The teenaged cock-sucker was obviously relishing the foreplay and savoring the preliminaries. Her mother knew the feeling well. The best part of sucking a cock was the moment when it exploded and the cum spurted into her mouth and throat, but that didn't mean she – or her daughter – couldn't enjoy the meat course before the creamy dessert.

Frostie drew her tongue up the veined underside of her sibling's prick, licking slowly from the thick root on up to the bulging crown.

She lapped up again, slurping wetly and noisily along the raised ridge of his ventral vein.

"Lick it, Sis! Yeah!" he enthused.

She flutter-kissed against the sensitive underside of his cockhead where it flared out from the stalk like a clenched purple fist.

His balls were as gnarled as a Gordian knot as they swelled huger by the moment. More precum spilled from his open pisshole.

Frostie was enjoying the licking, but the experienced teenager realized that her brother was liable to get his rocks off at any instant – and she sure didn't want him to shoot before his cock was in her hot mouth.

She drew her tongue up and down a few more times, then turned her radiant face down over his cock-knob. She kissed it and worked her nimble tongue into his pisshole.

Then her lips parted and she pushed her head down, taking his cockhead into her facial fuckhole.

It was driving Rachel crazy to see this, Frostie's cheeks sucked in as she nursed and puffed out as she blew down his cock. Her lips were unpeeled, turned outward on his prick just under the knob.
