Sensing her captives body beginning to to go lax, Vanguard lets out another tentacle, wrapping it around her waist to support her, [I assume the pleasure is sufficient?] he asks, starting to grind the textured phallus even faster into her.

Her breath started to become heavy, letting out soft moans she nodded unable to speak as she watched the bumpy tentacle thrust in and out of her now more then willing body "ooh!!"

Vanguard takes that as a yes. He pulls Yukis arms behind her, causing her chest to just out even more, giving the tentacles a better hold on her teats, which they exploit, wrapping just a bit tighter, the thinner ends rolling her nipples about softly.

with her fully supported, Vanguard increases the speed of his thrusts, scanning his captive for signs of orgasm.

she arched her back as he pulled her arms behind her, with each hard thrust her breasts bounce gently even though the tentacles held on to them tight, she tenced up a little more feeling her climax almost brought to the brink

A thinner growth extended from the base of the phallus violating her tender pussy, extending till it can wrap safely around Yukis clit while the larger part thrusts faster still.

[Please, dont hold back, simply relax and let loose]

with that remark, the tentacles begin to intensify their efforts to push Yuki over the edge.

her eyes widen slightly at the newest addition to her pleasure letting out a scream finally getting pushed into climax her body shuddered slightly and then finally slowly relaxed after she finished

[Phase one is complete. Phase two initiate.]

It was unclear what the monster was saying, but it became clearer as a panel slid open on Vanguards crotch.With a whirring sound, a 10x3 inch metal organ reveals itself.

The tentacles lift Yukis legs into the air, allowing for better access to her sweet damp sex. Vanguard walks closer, the tentacle in its targets cunt pulling out, only to be replaced by a larger shaft as he positions himself. Without further warning, he drives his entire girth into the young girls sodden pussy, fiiling her completely.

she barely had time to catch her breath when she was assulted by another shaft, she cryed out with a loud sweet moan her arms seeming to over power his tentacles for a moment only to grab at him wraping her arms around his shoulders, clinging to him tightly

Vanguard had failed to calculate her strength under stress, but this didnt matter, as his target wrapped her arms around him, that silver skin feeling warm to the touch. He hooks his arms under her legs and starts to move his hips, slowly starting to thrust as tentacles hold her agaisnt him, his member starting to vibrate as her tight passage is violated.

he could feel walls of her warm hole pressed against his shaft, a convenient design attribute, making him "grunt" every time he presses in, now picking up speed as it aims to complete its objective.

she her tight slit was like a vice around the creatures thick cock, while her body trembled, she felt the vibrations coming from his shaft she muttered softly "Ooohh...wh..what are you mmmm..."

[I.. am.. Vanguard] he replies. He continues to thurst into her, waiting for the optimum time to release, but unrelenting in pleasuring Yuki as the thin tendril wraps and tugs on her clit once more, the tentacles on entrapping her breasts roll and squeeze those pink orbs of flesh with much delight.

she moaned louder tencing around his thick shaft "Oh pleease va...Vanguard...d..dont stop" she bit down on her bottom lip slightly her body felt as if her body was on fire from all the stimulation

He doesnt plan to. Vanguard pounds into Yuki with machine precision, each thrust tuned to give non-stop arousal to Yukis pussy as the member starts to get warm in preparation for release.

the apendages holding to her ankles move to hold her legs, leaving Vanguards hands free, using them to molest his targets tender backside, groping them firmly.

She couldnt believe what she was saying but in all honesty, it felt great she couldnt help but want to hold back as long as she could which was becoming more and more difficult the more he sent waves of pleasure all over her body. "I..Im so close...ooh.."

Vanguard keeps up the pace, the vibrating member growing slightly as it prepares to inject Yuki with its fluid. He coordinates his tentacles to stimulate all her sensitive spots simultaenously, her breast being kneaded as her nipples get pulled and rolled by steely appendages, her swollen clit flicked and toyed with, even the tentacles on her legs assist by stroking her inner thighs softly, his metal hands gripping onto Yukis rear just enough to leave handprints on them if he let go.
