They both felt it. A twang, or soft snap. It could mean only one thing.
"Did the condom just-?" Jess asked from under the table.
"Yup," came David's voice, sharp and tight. He had suddenly stopped thrusting and was holding stone-still. His hard cock rested deep within Jess, equally still, and magnificently hard. He was tensing, which made it all the harder.
"I'm not on the pill-" Jess started to remind him.
"SHH-SHhhhhut up." David commanded, though his voice was unsteady. "Don't... move."
As step fathers go, David was great. Jess's mom had married him just a couple of years ago, and Jess knew as soon as she met him that she would someday fuck him. He was actually a decent guy, but weak when it came to lust. His eyes could always be caught lingering where decency would dictate they should not.
Jess would normally be put off by this, as in most men it came across as creepy, but in David's eyes when she caught him was a mixture of lust and shame. He knew better, he wanted to be better, but he was powerless against the seduction of a woman's curves.
So Jess made it impossible for him to succeed in being a better man. Every time she came over to visit, she wore low-cut tops and short skirts. She'd bend over a lot, or lean over next to him while wearing a particularly loose blouse. Bras were almost never worn under tight t-shirts, unless they were the kind that shoved her cleavage up to her collar bones. On the occasions when she had a longer break from classes, she'd sleep over in her old room and wear as close to nothing as she could pass off as "pajamas". Jess wanted David to look, because she wanted him to desire, because she wanted him to lose his self-control.
And so it came to pass in less than a year that she and David fucked. It was fantastic. The man was clearly sexually talented, but the idea of fucking a married man, a man married to her own mother for that matter, drove Jess absolutely wild. They were normally smart, usually careful about their coupling, but lately Jess had begun to demand sex in more daring scenarios, often when her mother was still home, and recently when she was even still awake. Today was such a day.
Patricia was upstairs getting ready for the party tonight, and Jess had successfully tempted David into whipping out his cock for her. They weren't stupid, of course, Jess had hidden herself under a tall bar table covered in a tablecloth that draped to the floor. Anyone walking into the room would just see David standing there, casually drinking a beer, with vaguely ruddy cheeks. Probably from the beer.
Jess had merely begun sucking David's cock at first. No one had arrived for the party yet, so it was just the two of them. As Jess devoured David's hard shaft under the table, they could hear Patricia walking around upstairs. Jess then got more daring and slipped the cursed condom onto David before turning around, hiking up her skirt and sliding herself backwards onto his shaft. David turned on the TV with the remote that was handily nearby and found a football game, which allowed him to make noises that could pass as reactions to the plays and ref's calls.
Everything had been going great, Jess was even building to an orgasm, when the damned Trojan burst.
