Lucy's Change chapter 2

I saw a smile cross her lips, before I shoved her against the wall of the shower. She put her hands flat on the wall and spread her legs, her cock dangling. I put my finger in my mouth, before not very gently pushing it in her ass. She started to move away from the wall, to get closer to me, but I pushed her back against the wall. It was my turn to dominate now. I pulled my finger out of her ass, and held her to the wall, with my hand on her neck and shoulder, before sticking my thumb inside of her. I could feel her new found prostate, and she gasped as I rapidly rubbed my thumb over it.
The lube I had rubbed on my cock was nearly all washed off, so I pulled my thumb out and pushed my penis in while I still had some lube on there. I held it there, balls deep, not millimetre between our bodies, until her anus relaxed, and then I started to thrust. I wrapped my hands around her waist, one arm wrapped around, and the other holding her by the ballsack, giving myself power to thrust hard and fast. The sound of our flesh clattering together and the water splashing around made us appear in a frenzy, and maybe we were, but I was moaning, and Lucy was on the verge of screaming. Every once in a while, I’d feel her cock swing back and hit my thigh, as I fucked her, as hard as she had fucked me, or harder. I don’t know how, but we ended up in the middle of the shower, away from the wall, and when I moved my arm away from her waist, Lucy, seemingly instinctively, bent over, and I could really go to town on her. Her screams faded back to moans, but a few thrusts later and she was screaming again. A few more thrusts and I felt her anus contract and her body seize. I kept fucking her through her orgasm, and after her first had subsided she began to play with her soft, swinging monster cock. I knew I wouldn’t last much longer, so I slowed my thrusts right down, and reached around to Luce’s cock. It was still soft, and stayed that way as long as I pulled on it. After several minutes of slow thrusts and jacking her cock, she started to moan “oooh I’m gonna cum.
