Going for a quick finish.

Looking over the android Tali knew that she was in love. She was sure that it was only a matter of days before the new Shepard would be begging her for pleasure. Even so bend over the desk like this with everything on display made Tali's heart jump with joy. She just couldn't help herself, it was hard to tell what gave her the most pleasure. Modifying Shepard or the inevitable sex afterwards.

Shepard on the other hand, was almost dying from anticipation. This artificial body contained so much pleasure and pent up sexual energy. Jane was almost certain that this would be the first orgasm of this body, and it really didn't surprise her. Just as she was wondering how attentive Joker was to his partners needs, and if it was even possible for Joker without breaking a hip, Shepard felt something thick slip deep inside her pussy. It felt amazing. She let out a huge sigh of relief as she turned over to see one of Tali's thick fingers deep inside of her own dripping android pussy.
Slowly Tali started to move it, forcing ripples of pleasure to course through Shepard quickly making her moan. Tali smirked as she fucked the android slut a little faster, making her finger work the tight artificial snatch. "oh my. You are soaking the floors little android." Tali whispered into her lover's ear. "Now i will count down from 10. And when i reach 0 i want you to cum for me."
Tali moved her fingers faster making the only responds Shepard was capable of giving a loud and slutty moan.
"10" Tali proclaimed. Apparently taking the moan as an agreement.
She moved her free hand to Shepard's moderate breast slowly fondling it and cupping it. The pleasure and pure bliss was clear on the androids face as the Quarian couldn't help but smile.

"9" The sudden squeezing on her breast made Shepard start to realize that the challenge here was not to be able to cum, but rather not cum before Tali had reached 0. The feeling of another finger slipping in Shepard's wet hole only confirmed this suspicion.

"8" Tali almost laughed as she could see the android struggling to keep in her orgasm. She, however, had seen the schematics of the horny little android, when she had installed the new mods, and she knew quiet well what to do to push her over the edge.

"7" Shepard felt the orgasm build inside of her. She couldn't stop herself. She needed this release so badly and yet it was kept out of reach from her. As a sudden pressing feeling against her ass suddenly appeared she couldn't hold back anymore. Looking back she saw a smiling Tali with two fingers in Shepard's pussy and one in her ass. The orgasm was earth shattering and the smiling face of the Quarian was the last thing Shepard saw.
