A sudden intrusion

As Dave hammered Cassandra, the door to the break room burst open.

"OH MY GOD," Rachel screamed when she saw Dave and Cassandra fucking.

"Oh, fuck," Cassandra moaned.

Jasmine threw up her hands, "You guys realize this room is supposed to be for employees only, right?"

Rachel ran over to Cassandra, "Cas! Quick! Give me the Breeding Pass!"

Cassandra's head rolled back onto Dave's shoulder. She was lost in ecstasy. She waved her hand, gesturing Rachel towards her pile of clothing on the floor.

Rachel picked through Cassandra's clothing, the whole time keeping one eye on Dave's naked cock thrusting dangerously in and out of Cassandra's fertile pussy. Where was the Pass? She went through everything, even turning all of Cassandra's pockets inside out, but there was no Breeding Pass to be found.

Suddenly Rachel caught a glint of something just underneath the couch. She bent down under Dave and Cassandra and reached for the Breeding Pass. She got it! It was right there, right where Cassandra had dropped it.

Wasting not a moment more, Rachel stood up and presented the Breeding Pass to Dave. "Dave, I want you to breed me, right here, right now!"

"What?" Dave slowed his thrusts, staring at the Breeding Pass in confusion. He had a choice to make. Either blow his load inside his own sister, or impregnate her best friend instead. Decisions decisions.

It wasn't a choice really. The glint of the card's hologram reflected in Dave's eye. He would comply with the Breeding Pass's terms.

"Mhph, get off, Cas," Dave moaned and shoved his sister off his cock.

"What? No!" Cassandra cried, landing naked on the floor, her pussy suddenly so empty.

Dave stood up and lurched toward Rachel, his hard cock glistening and twitching.

Rachel lay down on the floor and lifted her skirt, exposing her pussy to Dave. She opened her legs. Dave knelt down between them and lay on top of Rachel. She guided his dick into her pussy. Dave moaned in pleasure, "Ohhhhhhh, Fuuuuucccckkkk!" He had been so close to cumming with Cassandra that no sooner had he entered Rachel than he was spurting his thick virile load, painting her insides with his sperm.

Rachel squoze Dave, petting his hair and kissing him on the cheek, "Yes Dave! That's it! You're knocking me up! I can feel it!" Dave continued to thrust and moan, his orgasm lasting for nearly a minute. Cassandra could only sit on the floor and watch as Dave planted her nibling in Rachel's womb.

Dave's sex act now finished, the effects of the Breeding Pass on Cassandra started to wear off. She sighed, immensely relieved that Dave hadn't cum inside her. Rachel had saved the day.
