This is now the third day in a row that I've been at the mercy of this massive black cock, but today is a little different. Today he is going to try something a little bit bigger on my little pussy - his fist. We were hanging out in his bedroom when he told me to go make sure my ass was clean. I went to the toilet and when I got back into the room he had a large towel on the bed. I climbed onto the bed and turned around - offering him my ass doggy style. He started working his fingers into my ass one at a time. It wasn't rough or dry, but his hands are not small by any stretch of the imagination and I started to feel the pressure building once he had all his fingers in and really began pushing to get it past the knuckles. It felt like I was really being used. I pushed into his arm a couple times and pulled away a couple times. I finally had to pull away to catch my breath because it was draining my energy and it hadn't gone in past the knuckles yet.

He told me to lay on my back and take it like a real girl would, so I laid on my back and once he started working his hand back in I couldn't pull away. He was starting to push really hard and I finally grabbed onto his wrist and pushed to get him to pull back a little bit. It worked a few times, but as I resisted he started to ignore me. I pushed and he pushed with my whimpering reaching ever higher and louder until he finally slowed and stopped. It hadn't gotten past the knuckles yet and thought that he might not be able to do it because he didn't think my hips were wide enough. I told him if he flattened his hand he might be able to get it in, so I got on my knees again and he started pushing it in. It went further and further until I couldn't take it and started pushing on his wrist again, but to no avail. He pushed harder and I whimpered louder until it felt like he pushed it all the way in, so I slide my hand down his wrist to my ass and there was nothing but wrist there. I have never been that full in my life and was so happy to have taken him all the way in. He pulled out and showed me how far he had gotten.

  He then pushed me onto my back, pushed my legs up and shoved his cock right in. He was slamming my pussy so hard that I started saying "oh my god" over and over and I'm not even religious. I was trying to keep from making any noise at all because his roommate just came home, but I couldn't stop myself. The black cock that was inside me was attached to a real man and he was taller, bigger and stronger than I was and he had me pinned down with my legs in the air. I was embarrassed and humiliated because the best I could do was try to muffle my voice. All this seemed to turn him on even more and, in turn, I got louder as he continued to pile drive my poor pussy even harder. This went on for at least 15 minutes when he let my legs down and I proceeded to wrap them around his body. This was much more relaxing because he couldn't get it all the way to the second entrance in my ass to abuse it.

  He slowed down and pulled out, so I laid on my side. My little rest lasted about half a minute before he pinned me down again. I was close to the edge of the bed and had to hold on with both hands. The only way I could have possibly slowed him down or stopped him was to say something and that didn't seem to work so I just took it because I was there to give him pleasure and satisfy him. He makes me feel like a girl and that's enough reward for me. He came inside again and that brings the total number of times to four.

When he pulled out, I felt like I could just keep going. I never realised that the hormones would give me an insatiable appetite for sex. I could fuck for hours and hours everyday and still not get enough. He says he's going to bury his arm to the elbow in my ass, force me to drink his piss and force me to strip naked in a public park. I'm so nervous, but I can't wait to submit to his every wish.
