The alien didn’t care about Liz protests and placed it against her opened entrance and began to push it inside. It flexed to her muscles of the passage and instead of just forcing her up she forced him together. As he slowly slid inward, there where no way she could stop the intrusion considering how slick it was. Once he got as far as he could, his strange organ had more to give but it just wouldn’t fit, he first waited a bit then slid back and the in again, increasing his speed for each thrust. The organ seemed to move inside her in more directions then just in and out, if twisted, turned, changed size in a way that just increased the normal sensation.
