The tempo of Mark's fucking increased feverishly until the rickety single bed began to shake. Then Lisa felt his rock-hard cock slamming violently in and out of her cunt, and she knew her boyfriend was fucking her as hard as he could. All at once she was hotter than ever before in her life. Her cunt was churning deeply with the pungent gushing of her juices, and her clit was twitching. She threw her arms wound his shoulders and ground her jiggling tits into his chest, fucking her eager cunt onto his big cock again and again.

"I'm gonna cum, Lisa," Mark moaned.

"Oh, no, Mark, not yet!" Lisa squealed. She bounced her ass of the mattress and fucked her dripping cunt wildly up at him, fucking him as hard as she could. "I wanna cum first! Keep fucking me! Keep doing it! Yes! Don't cum! Unnghhh… unnghh… unnghhh…"

But the sucking tightness of the teenage girl's virgin cunt was more than the boy could resist. For a moment his cock pulsed to absolute stiffness inside her cunt and his heavily dangling balls tightened. Then the second load of his cum began to shoot wildly, deep inside Lisa's cunt. The thick white jism spurted hotly out of his bloated cockhead into his girlfriend's steaming cunt.

Lisa gasped with the unfamiliar sensation and lay motionless on the bed, feeling Mark fuck her cunt full of his boiling cum. For several seconds Mark continued to fuck his spurting cock painfully in and out of the clinging lips of her cunt, wincing as the last droplets of his jism shot out of the twitching slit of his purplish cockhead. Then with a heavy sigh he rolled away from her sweaty body, pulling his softening cock out of her pink juicy gash.
