My brother is my DD (part 1)

I'm Zoe I'm 22, female,about 5'3 and 120. My best features are my 34C titties.
My younger brother is 19, Joe he's 6'6" and is a solid 220.
Since he is too young to drink I pay him to be my DD.
One Saturday night me and my roommates went out. No guys went this night. We all got drunk. Not hammered but drunk.
I texted my little brother to come pick us up and drive us home.
Joe picked us up. I sat up front as I get car sick if I sit in the backseat.
On the way home we begged him to take us to Waffle House. He gave in. So all 5 of us piled into one booth. I sat on the side with Joe.
I got cold as my club outfit wasn't keeping me warm now that I'm not dancing. I cuddled close to my little brother. He moved his arm so I could put my arms closer to his side. He placed his hand on my bare thigh.
I didn't think anything of it. After the waitress brought our drinks Joe placed his hand back in my thigh but he moved his hand mid thigh. His fingers pressed my bare skin a little harder.
This got my attention, but I didn't think anything else about it as me and my roommates were laughing and making fun of each other.
Once our food was brought we all ate. Then we were all sleepy so we loaded up and Joe drove us to our sorority house.
As there is a no boys allowed upstairs Joe helped me to the couch. He laid me down and covered me with a blanket.
I reached out to him and pulled him close. "Don't leave me Joe" I slurred.
"Ok. I can stay for a little bit" he said. I pushed myself up and he sat down. I laid my head on his lap. His shorts riding high on his thigh.
I tried to get comfortable but couldn't. I lifted up and reached back and tried to unhook my strapless bra.
Joe reached his hand under my shirt and unhooked my bra. I pulled it off and laid back down.
I could feel the cool air on my titties which caused my nipples to react and become hard. I briefly thought that my titties must be handing out of my shirt. I was too drunk to care.
I felt Joe place his hand on my bar shoulder. He turned the TV on and started flipping channels.
I began to doze to sleep until I felt Joe moved his hand from my shoulder to my chest. His fingers were touching my side boob.
I was fully awake but wanted Joe to think I'm asleep. So I focused on my breathing and made it slow and deep.
It wasn't long before Joe slowly moved his fingers to cover my whole tittie. He just held his hand still for a minute then he began to squeeze softly.
I continued to pretend to be asleep. Focusing on breathing and not responding to how good my little brother's hand was feeling.
He moved his hand using only his fingertips as he lightly caressed my tittie. Circling my hard nipple then back to my whole tittie.
I moaned softly and rolled more on my back giving him more access to his big sisters titties.
He adjusted under my head and I could feel his hard on.
"Holy fuck" I thought to myself "how is turned on too."
Joe moved his hand to push my top down below my titties. Then he moved his hand to my other tittie. His fingers squeezed then drug his fingertips lightly across each tittie.
I felt his other hand moving on his lap next to my head. Then I felt his hard cock touching my hair. I felt Joe move his hard cock and rub it in my long hair.
He kept groping my titties as he stroked his cock using my hair.
I could feel my pussy getting wet.
I couldn't believe I was so turned on by my little brother, but I was.
I moaned and rolled more on my side, then on my back then on my other side.
I sat up, keeping my eyes closed and I shifted to put my head on the other arm rest. I placed my bare feet in the lap of Joe. Then I curled up in a ball. I made sure to pull the blanket up till my mini skirt was barely covering my ass.
After a minute I felt Joe move closer to me. His fingers slid up my thigh. His fingers slowly lifted my skirt to completely expose my ass.
I heard Joe moan when he saw my thong wedged deep between my ass cheeks.
His hand slowly grabbed my ankle and moved it giving him access to full view of his sister's ass.
His hand grabbed my ass cheek. Then he pulled my ass checks apart. This caused my pussy lips to separate causing the fabric to wedge between my pussy lips.
Joe moved his fingers to the black fabric and he pressed it deeper between my pussy lips.
I couldn't hold back my moan as the rough fabric against my clit.
Joe didn't stop. He moved his fingers and pinched the fabric pulling it to the side.
His finger slid inside the fabric and ran his finger from my clit to my pussy then back again. He moaned and sharply inhaled as his finger moved.
With his other hand he was stroking his cock. I could tell the way he was shaking the couch.
Joe slid his finger into my wet pussy. He moaned again. Only one finger and only the tip.
"Damn Z, you're soaked" he hissed.
Then he slid his finger deeper.
His finger is thick and rough. The way my pussy welcomed it by being hot, wet and tight was intoxicating.
I moaned softly and arched my body trying to get more of my little brother.
Joe began to finger fuck me. Bringing his finger out to the tip then knuckle deep. He would bring it out and smear my pussy juice when he would move his finger to circle my clit then back into my pussy.
He was still stroking his cock as his stroking has the couch shaking with him.
I moaned again as Joe slid another finger in my pussy. He finger fucked me with two fingers now.
Joe began to finger fuck me harder. His fingers slamming as deep as he can get them. Causing my whole body to move with each thrust.
I moaned again, louder longer as I was responding to my little brother's finger fucking. My pussy throbbed and gushed pussy juice around my little brother's fingers as they stimulated my gspot.
Joe moaned and then grunted. He was breathing heavy and his movements slowed. I figured he must have came too.
He pulled his fingers from my pussy. I felt him cover my body and he stood from seating on the couch.
He kisses my forehead before leaving.
