He whimpered.

His prick expanded inside her and her pussy pulled and sucked on it, her circular pussy muscles clamping closed in a series of concentric rings that ran up his stalk from root to crown, as if she was jacking him off in her cunt. She seemed to have an internal mouth up in her cunt, sucking on his cockhead. Mike gasped with delight. This girl might be a slut but she sure had a nice cunt!

Then Tina began to rise and fall, riding his towering prick in a slow, steady tempo.

Mike stirred under her, unable to fuck properly with her weight on his lap, but he moved his prick around with a grinding motion as she corkscrewed down onto it. His cock filled her cunt. Then she drew up until only his fat cock-knob was still buried in her, paused, then pushed her cunt down all the way again.

His hands slipped down, cupping her mobile ass.

She reached down under her crotch and got a handful of his balls, massaging and squeezing gently.

Her chin rested on his shoulder.

Mike assumed she was clinging to him in desire, not aware that Tina was staring into the back seat and getting a good eyeful, now. Her gaze switched back and forth from Clyde's prick to Linda's cunt. She was licking her lips. She saw preliminary spunk foaming from Clyde's cockhead and her tongue tingled. When she saw the cunt juice running out of Linda's cunt, her mouth watered even more.

She was wishing that they would do more, though.

She wanted Linda to lean down and take Clyde's cock into her sweet lips. Watching a blowjob was more exciting than watching a handjob, Tina reckoned.

Linda was really getting carried away, her fist flying up and down, Clyde's cock and her clit was throbbing away in passion.

Inspired as much by what she was seeing as what she was doing, Tina began to climb the spiral of lust towards the crest. Her cunt rose and fell and began to cream. "I'm coming," she squealed into Mike's ear. "My pussy is creaming on your big prick!"
