I reached down and started to play with myself, as he thrusted deeper into me. He moaned out as I pushed myself back, forcing him further into me.
"Pup, what do you think you're doing." he growled and tightened his grip on my hips. I screamed, getting closer to release.
"I-im close." I whispered. Nan Shen slowed down, causing me to groan.
"You're not allowed to cum until I do." he said as he reached down and grabbed my cock. He started to tease me, but stopped. Then he put his thumb over the end of it, blocking me from cumming.
"Like I said, you are not going to cum until I do." he moaned as he began to move faster.
