No, you let it pull you.

You realized that because it was focused, it would have probably hurt you if you resisted, so you let it drag you into a room where it pushed you against the wall. Another tentacle came and removed your tanktop, exposing you breasts. Then the wall moved and locked your wrists inside of itself. so you couldn't escape. Then two tentacles which had needles at the end moved in front of you. You started to struggle, not wanting to be injected with needles. But other tentacles held you still. Then needles moved to your tits where they pointed themselves at your nipple. They then stuck the needle inside, you flinched but it didn't too bad. You then started to feel some sort of fluid being injected inside.

You tried to look for a change in your tits and you saw one alright. In the span of a few minutes you went from a J cup to a P cup. Then the needles pulled out and the wall let you go, you fell onto your large tits. You pushed yourself up and started messing with your boobs. They were heavier as well as larger, feeling like they are now 15 lbs. You then left the room and went back into the main chamber. You didn't see a tunnel upwards, thankfully. But you see some going foward, one left, and one right.
