He had to fight off the impulse to stroke savagely in and out of her. He had to be gentle and patient until she relaxed and got used to the sensation of being fucked. He knew from experience that after a while, she would reach the point where he could man-handle her at will, and she would enjoy every moment of it. But, for the time being, she was still frightened and in awe of the unusual sensations that were stealing through her for the first time.

"Oh, my sweet sister, you're so honeyed and warm and tight up there!" Jarvis gasped in fervent tones.

He ran his fingers up her side and caressed and played with her breasts, tickling the nipples with his cuticles.

He began to slowly, cautiously, oscillate his hips, stirring his throbbing log inside of her. Melanie gasped as the movement sent darts of pure ecstasy through her. The slightest movement of the bulging tool within her sensitive, silken chasm sent bursts of intense pleasure coursing through her body. With a sob of awakening pleasure, she slowly lifted herself off his lap, letting a couple of inches of his rigid, slippery cock squelch out of her. Then, she sat back, taking the entire length inside of her again. A shock of exquisite rapture tore through her and she cried out loud in astonished ecstasy. Eagerly, she lifted her hips higher into the air this time and dropped her weight upon him hard, impaling herself wantonly on his uptight spear. It felt so good she nearly screamed! She began to bounce on him with abandon, swiveling her hips and churning her heated insides with his tumescent ramrod.

Jarvis groaned in delight as she began to pump his solid truncheon with her hot, sweet sleeve. He dropped his hands from her bouncing, jiggling breasts and gripped onto her hips, guiding her down onto him. At the same time, he began to draw back his hips and hump them forward lewdly, driving into her deeply each time she came down on him. Melanie didn't mind his actions in the least. No sirree, she was adapting to the sensations of getting fucked like a fish to water! Jarvis grinned lewdly. Hell, his sister was one of the hottest little sluts he'd ever come across!
