More than satisfactory

6T9 slowly pulled down the thin silvery blanket that was still covering your manhood. As the material slid downward, your mighty cock sprang free. Its length and girth looked enormous compared to your original one. Long dark-colored veins along it's side throbbed in sync with your heartbeat. Meanwhile, the shaft's coloration was a dark tan, but it wasn't too far from your own skin tone. Even the head had a slightly different shape, being somewhat more rounded than the earlier helmet. Only the skin on the head near the opening looked familiar, as it was apparently the only part they'd been able to save.

Delicately, 6T9 reached out a hand and grasped it. You could feel each finger gingerly caressing your cock, and eventually the motion changed over to a slow stroking of the entire shaft. Although you generally didn't like hand jobs, this felt amazing. You suddenly remembered one of the girls you knew that always started this way, so this was something else that 6T9 had apparently gleaned from your memories.

"Do you like that, Sky?" asked the robot. You didn't remember telling anyone on board your name, or the shortened version. This must be yet another thing that 6T9 had learned to try to improve the experience. You simply nodded to show your approval.

Steadily, the hand began moving faster, and then a second hand joined it. With your old dick, this much stimulus would have probably pushed you over the limit. Although the hand movements felt wonderful, your new giant-sized tool seemed capable of enduring this type of action for hours. Meanwhile, the pressure in your abdomen slowly kept increasing, and now a new sensation joined it as your reconstructed balls began to ache slightly. "Let's try something else," you whispered, hoping to find a position that would speed things up.

In one smooth, graceful motion, 6T9 pivoted on one knee, while lifting the other over you body, and shifted her lower body toward your face, assuming a seemingly rehearsed 69-position. Moments later, you felt lips gently kissing the head of your cock while you stared in awe at a perfectly shaped pussy right in front of your face. You immediately reached up and grasped each ass cheek and began to massage them, wondering how they would feel. Surprisingly, they felt quite real, as their degree of firmness, resistance to squeezing, slight jiggling motion, and even the body heat all seemed quite natural.

Soon your tongue joined the action, licking the edges of the glossy slit, before eventually focusing on the clit. Amazingly, 6T9 seemed to react to your stimulus. As you playfully kissed and nibbled around the button, the robot's body seemed to quiver in response. Was this just more of the robot's programming, or did 6T9 actually feel and react to the stimulus this way? Curious to find out, you began playing even more vigorously around the sweet spot, eventually sucking on it with more and more ****.

All of a sudden, 6T9 arched her back and lifted up her shoulders while shouting, "Yes. Yes! Oh my god!" Afterward, she quivered for several seconds. Although it may still just be a machine, based on this reaction you had **** but to think of 6T9 as female, at least in this form.

"Now it's your turn big boy," she whispered, and immediately you felt lips surrounding the head of your cock. Next you sensed the entire head entering her mouth while her lips wrapped around the very top of the shaft. Soon she was moving her head up and down while taking in the head a bit deeper each time. Before long it was hitting the back of her throat where her tonsils began stimulating the head as it passed between them. The sensation was incredible, yet your giant-sized dick still needed more. You reached down and put your hands behind her head and began to press gently, encouraging her to take it even deeper. In response, she lifted her pelvis slightly and lowered her shoulders while tilting her head backward a bit to get a better angle. After a few more bobs of her head, she had managed to engulf the entire shaft. Next, you gave her subtle cues with your hands showing her the amount to move while you simultaneously began thrusting your hips to achieve a maximum length of the stroke. Quickly 6T9 understood your wish, and she began bobbing her head in sync with your hips. With each cycle, you pulled your cock back to the point where her lips wrapped around a sensitive area at the bottom of the head where it joined the shaft. Then you thrust your massive meat into her while her head came forward and downward, plunging your huge dick deeply into her throat. Her wondrous deep throat motion began slowly, but soon the pace quickened.

Most men probably would have shot long before this, but your giant tool was still not satisfied. Then you had an idea. Tilting your head upward, you once again found her clit and began to suck. Immediately, 6T9 began to quiver, and before long you could tell she was about to have another orgasm. Just when it felt like she had reached her peak and was about to lift up, you pressed downward with all your might to **** your cock all the way in to the point where you could feel her nose buried between your balls. With the added orgasmic vibrations coursing through her entire body, it was enough stimulation to finally push you over the limit, and you sensed that telltale surge of a forthcoming ejaculation. As tingles flooded your body, you felt massive spurt after massive spurt flowing through your dick before finally getting released somewhere deep inside 6T9's throat. Normally, you were used to orgasms only lasting a few seconds, but the bursts of semen continued well past that. The pressure was finally being relieved in your abdomen, and as your seminal glands steadily emptied, the sensation there was not unlike the feeling of taking a really long and satisfying pee. However, this was so much better because it combined that feeling with the bliss of a seemingly endless orgasm as well. After what felt like well over a minute, the flow eventually stopped and your mind-blowing climax finally came to an end.
