But suddenly he howled.

The man had gotten so turned on while he was sucking on Dolly's pussy that a few strokes up through the cleft of her tits had brought him to the peak.

His balls erupted and his lust-lava came gushing up volcanically, squirting from the head of his pistoning prick before Dolly had a chance to take it into her mouth.

She dove down to dine, but his cock missed her lips and skimmed up her cheek and his hot, thick cum-load shot straight up and plastered the roof of the car.

He groaned and sank back, trembling.

His cock slid back into her deep cleavage, and Dolly tucked her chin to her breastbone and waited with her mouth wide open, expecting his cock to stab up and shoot a second spurt of cum into her throat. But he had stopped humping.

The man had been so frenzied that every drop of his cum had pumped out in a single gush.

The gooey cock-slime was clinging to the roof of the car and a slimy shard stretched down, then broke away and fell, splattering on Dolly's tits.

She could feel his prick starting to shrink and soften as it lurked in her deep cleavage like a lizard in a cave.

She was disappointed. The cock-loving teenager had been looking forward to a drink from his prick.

She moved back and his big cock slipped from her tit-tunnel and flopped around, limp now, but still a fat and meaty thing, the cock-knob glistening.

"Well, young lady, you've certainly passed your test," he said, seemingly content with a tit-fuck.

"But you didn't," she replied.

He frowned and looked puzzled.

"Premature ejaculators don't get a passing grade from me," Dolly explained. Then he understood, and he grinned happily.

"Can I take the test again?" he asked hopefully, their roles reversed now.

Dolly pretended to think about it. But that was just a bit of teasing. She wanted the second half of the oral exam as much as he did.
