Her expressionless behavior was enough to send a chill through Rahs' spine when she was doing these kind of things. I really gotta get someone to give her emotions or something... if that's possible at all. Her passage did resemble a woman's cunt even with the suction that was felt as the tightness clamped down on him.

"How much longer until you need to enter a sleep cycle?" He asked as he looked at her indifferent eyes as her cunt squeezed his cock.

Her brain checking her internal clock she looked down at him saying"12 hours." She had not started to move her body yet, lacking a command to take her work further. However as her body adapted to having the massive girth inside her, her inner walls seemed to start moving on their own caressing the throbbing length as she straddled him.

12 hours plus how long her sleep cycle will take... The mercenary wondered if there enough time to do this cute robot girl a favor and get someone to give her something more human. As he laid back trying to think, he noticed that her cunt's walls were automatically rubbing and caressing his length but she wasn't moving at all. "Go on, start fucking me," Rahs ordered a bit lazily, as if it was kind of obvious what he wanted her to do, but she was just following her program so he couldn't get mad.

At the command Rin started to slowly pull herself up and down the massive length while steadily increasing her speed with each pass. The situation must have seemed quite odd to the mercenary, her body working his so expertly but her expression did not change seeming somewhat determined looking or perhaps bored, depending on how you looked at her.

The soft feeling her cunt created and its tightness started to move up and down on the swollen rod that impaled her. It was then that the mercenary realized two things: Rin was way heavier than she looked and was glad she wasn't resting on him completely; the second was that her expression hadn't change whatsoever during the whole time he looked at her face carefully.

With a sigh, his mind somewhat blocking the pleasure coming from her passage, he couldn't keep looking at her nor fuck her if she stayed that emotionless. It was like doing it with a piece of wood. "Hey, can't you moan or fake some pleasure at least?" Rahs asked with a bit of annoyance and curiosity, wondering if the scientists forgot to add that simulation or if the ADD removed it. He couldn't help but think that she was in dire need of an upgrade. But first things first.

Rin slowly moved up and down the thick rod, looking down at his annoyed face and saying "If that is what you wish." With that, each movement along his thick rod elicited a reaction from her seeing a convincing pleasured expression on her face and a chorus of moans beginning to spurt from her lips. They were hardly convincing, compared to those of a normal woman but it was the best her limited sexual experience could provide.

Guess she isn't complete after all... To the mercenary it had been an awkward sensation to have an emotionless robot mount him and impale herself, but that didn't make her techniques any less satisfying. Almost as soon as he commanded she accepted the new order and her face changed to one of pleasure, but her moans, though long and continuous, didn't have that ring that a real girl has. But it was okay for then, he may have to do something about it later.

With the fake emotions now being showed, Rahs could feel once again how her artificial vagina moved on its own while Rin rose and dropped herself on the massive cock. The tightness and squeezing motions created waves of pleasure throughout the swollen member which made the mercenary reach out to hold of her breasts, realizing that the skin she had was actually very soft but somewhat cold.

Rin moved tirelessly to pleasure the throbbing member filling her tight cunt continuing to move up and down with no sign of stopping as her fake 'emotions' seemed to satisfy the mercenary. When he reached up to grab her breasts, her small orbs reacted almost as a human's would firming slightly as the soft pink teats hardened in simulated stimulation. Her skin was quite a bit colder then a normal woman's but it was more then made up for by the perfection of her skin and the softness of her pert breasts.

Rahs noticed the change in Rin's nipples, and he couldn't help but to think that she was truly meant to be the sex toy she was built to be. Her mounds were small compared to the description the scientists offered but they still were pretty soft which surprised the mercenary somewhat. He had just fought the android, and to find that she was actually a bit softer than she looked was weird.

Along with the increasing pleasure that spread throughout his body, the same could be told from the commander on the floor. It seemed she had recovered somewhat and started to stare at the robot and the alien fucking with an envious look. She had started to masturbate lazily due her fatigue but her moans accompanied the ones emitted by Rin. The tight and velvet-soft cunt of her made Rahs think of what possibilities lied before him. "What other nice tricks can you do, Rin?" He asked, expecting something only a robot like her could do that differed from a girl.
