Cock In A Box Cums All Over

I open the door to find a HUGE moving box. There is no label or return address on the box. I tried to bring it inside but it was so heavy! What is in this thing!? After finally getting it in the house, I saw a piece of tape. It said "Pull Tape". I did and a cock fell through! I wasn't sure what to think of it! I touched it and eventually couldn't keep myself from sucking it and fucking it until cum splattered out all over the place!
