Tina was gurgling with pleasure. Her sensual lips dragged up Mike's thick stalk and slurped hungrily on the fat purple head of his prick, then her head bobbed down again and she fed almost the full length of his cock into her mouth.

Mike was panting like a steam engine. He had one hand on the back of Tina's head but it just rested there lightly. The cock-hungry girl needed no guidance and no encouragement. She knew what she was doing – and it was what she wanted to be doing.

Clyde and Linda exchanged a glance. Clyde grinned.

Linda didn't dare grin. She didn't want to draw attention to her mouth!

They both looked back at Tina.

"Ummm," Tina sighed, as her lips dragged up.

Then, sucking on his cockhead, her cheeks hollowing in, she purred with voracious delight. Her head continued to fall and rise in a slow but steady rhythm.

Will she keep on doing that? Linda wondered. Is she going to let him come in her mouth? Ooooh! Does she swallow it?

Tina glanced sideways.

When she saw that Linda and Clyde were both leaning over the back of the seat, watching her, she gave a little giggle, the sound muffled by Mike's prick, and her lips turned up in a smile around the smoking slab of his cockhead.

It was evident that the naughty nymph didn't care that they were watching her – she seemed to enjoy their attention, in fact, for she began sucking even harder and more attentively. Mike had a huge grin on his face, his head thrown back, eyes narrowed.

"You lucky bastard," Clyde rasped.

"Yeah, baby – that's it!" Mike moaned. "Ohhhh – suck it, baby – suck me off!"
