You can't reach 8"

Holding the massive plastic cock with one hand, and lubing it up with the other, Angelina advances on you and binds your hands to the riding post. "I could put the ball gag back in" she says "but I want to hear you scream, slut!" and she places the head of the cock at the entrance to your already sore ass. She doesn't bother with kindess or mercy, she simply forces the first 4 inches in with one vicious thrust. You let out an animal scream that reverbarates around the room but she doesn't stop. Another inch enters you, and another, each one bringing fresh pain. Tears drip down your cheeks but Angelina still doesn't stop. At 7" she suddenly halts. You realise it is not because she has chosen to, your tight ass is simply too small to take in the remaining 6" of the strap-on. Angelina curses at you and smacks your ass hard but its physically impossible for her to continue. She pulls out of your ass, bringing another scream to your lips, and says "You've really done it now. I told you that if I couldn't get 8" in there, there would be trouble!"
