At other times, she speeded the process up by stroking his cockshaft while sucking on the cock-knob – jerking him off into her mouth, in effect. It was not as gentle and tender that way, with her fist doing most of the work, but it got the job done in a hurry and was useful when they did not have a great deal of time, or when Catherine happened to be really starving for a load of jism.

Again, she might use only her mouth, but bob her head up and down so that, instead of sucking only on the fat cockhead, she took the whole long prick into her mouth – and even down into her gullet – deep-throating him with a steady rhythm.

Often she did not use her mouth at all, but only her hot and nimble tongue, lapping and laying the cock-knob or tonguing up the prickstalk until his creamy cum spurted out in a torrent, skimming past her cheek. Then she would gather the delicious stuff up with her questing tongue, licking his cockrod and prickknob glistening clean.

Sometimes she liked to have him jerk himself off in her mouth, or on her fat tits, which was not really a blow-job at all but had the same end result when she subsequently sucked his prick-knob and slurped the spunk from the big slab of purple cockmeat.

And the positions changed, as well.

She loved to kneel down in front of him as he stood, giving a classic kneeling blow-job just like a whore in an alley. Sometimes she did this outdoors, in the back yard, thrilled by the idea that one of the neighbors might see them. Once or twice, she had done it when they were at someone else's house, at a party, taking Robert into the bathroom and kneeling before him with the door unlocked, driven to wild joy by the thought that anyone might walk in and find her with a mouthful of prick.
