He felt like laughing at all of her crazy contortions. He knew if he felt at all like doing it, he could take his cock from her cunt and shove it up her ass and she'd keep right on going crazy. His fingers dug deeper into her tits, and she screamed, but she didn't stop going crazy at all. Far from it, her contortions grew even wilder. Her legs went around his flying hips, her heels dug into his asscheeks, and now as his balls slapped harder against her wet crotch, Jim felt the same sort of craziness sweeping over him.

"Fuck me!" she cried. "All the way! Do it now!"

Jim was fucking insanely, completely out of control, driving his cock into her so hard and so fast that the friction was building up even more heat. He had cum before, but never at all like this, and his jism hadn't even started to spurt up from his balls yet.

When it came, it was like molten fire, the purest sort of ecstasy coursing all through his naked body. If he thought his aunt was beautiful and sexy before, now he saw her as she really was, the most wonderfully wanton woman that ever was, perfectly gorgeous and special in every way. Jim had to hold onto her quickly thrusting hips as the ecstasies threatened to rob him of all his coordination but even so, in their wildly climactic thrashings, his cock slipped out of her cunt and spurted a long white streamer of jism up over her belly and onto her tits.

"God damn it!" she snapped, and with one quick grab for it, had it back in the hole it was made for, and Jim was fucking away again, though the wonderful climax had peaked and passed and there was now a long track of jism reaching up from the black hair of her cunt to the pink of her bobbing nipple.

Her legs locked around his hips. She grunted and gritted her teeth as she pulled him inside her with frightening force, and then, just as quickly as before, she relaxed with a smile and lay back on the couch, quite serene and contented, uncoiling her legs from around Jim's back.
