I reached down and licked Mary's pussy softly as she moaned in appreciation."Oh Jeff!" She gasped, "Lick me good! Please lick my pussy and asshole lik... you did before!" I was glad to comply and gave the pretty teen a series of long loving swipes of my tongue all over her bare pussy and tight asshole. I could taste her arousal now as Mary was becoming increasingly excited by our sex play. I also knew we didn't have forever today to do everything we both wanted.And so I moved up directly behind. I planned to interlock the walls at the corners with some steel reinforcing rods that we had found to keep the walls from tipping over. It also dawned on me to put some dimples in the top surface of each layer to make them interlock in a manner similar to Lego blocks.This first room was 12 feet by 12 feet and had three doors, one in each wall. Not knowing what else to do, I had Jake fashion three doorframes from two-inch-thick and 10-inch-wide wooden planks. The same technique of wall. She cried for more. I tried to keep it up and all of a sudden, she screamed, fell forward, and acted like she was fucking the bed. Rubbing her cunt up and down the bed. I remembered her fingers going in my cunt, so I rammed three fingers between her bruised cheeks and right into her pussy. She was still spaseming and I could feel some cum leaking out of her pussy, and it made it so easy to go in. It was so easy, I put in four fingers. She shoved her cunt up in the air and said “more”. I tried. “I will not give you a over the knee spanking but you can stand by the desk and lower your pants. I will start with the small hairbrush and see how you like it.” So I walked over to the desk, lowered my slacks and bent over. “Put your elbows on the desk, be sure and stay in position, and spread your legs.” I didn’t think going to get office supplies would lead to a spanking like this. I still had my undershorts on and when she started to spank me, I could feel it but she wasn’t spanking me very.
