Triplets weekend (part 1)

I'm the middle triplet. I'm Sara I'm 5'8" and I'm at about 160. My older brother Stran is taller at 6'and about 200. My younger brother is Sam he's 6' and is 190.
We are 23. We have been celebrating our birthdays by ourselves since we were 16.
We are super close. We all live within a few miles of each other and we hang out at least 2 nights a week.
I'm 32 weeka pregnant and the boys have been ecstatic for me. We agreed to take a 3 night cruise.
We realized the mistake when we all had the same cabin. Instead of each having our own.
We didn't let that stop us. We decided that we would each take turns sleeping on the single bed and the other 2 would sleep on the king bed.
After the safety briefing we decided to head to the casino. The boys started double fisting the margaritas. I sipped on my club soda getting teased mercifully by the guys.
I decided I was going to go lay down before the night dinner and shows.
I decided to strip down to my bra and panties. I rubbed my very pregnant belly till I fell asleep.
I was awaken by the mattress shifting. I laid still not wanting to cause any embarrassment by getting caught in my undies.
I felt mattresses shift again. I peaked and saw it was Stran.
I could smell the alcohol as he was breathing heavy.
I felt his hand rub my belly. The warmth of his palm made my body react. His hand slid along the top of my belly. His finger tips brushed against my lace bra. Then he dragged his fingertips back down across my belly.
Once his fingertips touched my lace panties he paused. I focused on my breathing trying to act asleep to save the embarrassment.
I felt Stran's breath on my belly. Then his lips. Stran was kissing my very pregnant belly. As his tongue softly licked my skin his fingers slipped under the lace waistband of my panties.
Stran moved his fingers slowly and gently till his fingertips touched my pussy hair. Stran let out a soft moan as his fingers pushed further till they found my pussy lips.
Stan continued to lick and kiss my stomach as his finger slid between my hairy pussy lips.
Stran paused and he shifted on the bed. He laid on his side facing me. I felt his breath on my tits. His hot breath reeked of alcohol. His hot breath on my cold full tits was so exciting. So wrong. Yet so hot. His finger slid deeper between my hairy pussy lips over my hard clit.
I moaned and spread my legs. I was shocked I did this. I was embarrassed, I was so turned on, I haven't been fucked for months. I was grossed out but I craved more.
Stan slid another finger between my now spread hair pussy. Both of his fingers were stroking my clit.
His tongue began to lick the roundness of my full tits. As he softly moaned.
I was so torn. I was so turned on. But it's Stran. My brother. This is so wrong. But holy fuck I was so turned on. I could feel my pussy becoming wet. I focused hard on my breathing not wanting him to stop but not wanting him to be embarrassed.
As Stran continued to lick the fulness of my tits his fingers slid past my clit and into my inner pussy lips. He moaned as his sister's hot creamy pussy juice coated his finger. He slowly moved his fingertips around the rim of my pussy.
His licking turned into kisses. His breathing was now panting. I felt his hips rocking rubbing his hard cock against his sisters thigh.
He moved his lips from my tits up my chest and neck.
His lips opened and he began to suck my skin. As his fingers dipped deeper into his sister's pregnant pussy.
I became startled by my own moan that escaped my lips. Stran froze. Still breathing heavy against my ear. He whispered breathlessly "tell me".
My mouth was dry. I nodded my head 'yes'.
Stran moved his hand from my panties. He brought his cum covered fingers up to his lips. I could smell my pussy juices. I turned my body into his. I slid my thigh over his.
I grabbed my brother's face and I began to kiss him. He rubbed his wet fingers across my shoulders as he hugged me closer.
Once our lips touched my body reacted. As my skin became covered in goosebumps.
My lips parted as Stran did his tongue into my mouth. I moaned as the taste of margaritas filled my senses.
Stran moved his hand to my full and heavy tits. His hand began to squeeze my tit as I ground against his thigh. Our moaning was now more primal, more raw.
Stran broke our kiss and he moved his mouth to my neck. He sucked my skin as his hand reach and unbuttoned my bra.
When the bra freed my heavy tits his warm big hand grabbed my hardened nipple. His mouth moved down to my chest as he pushed me onto my back. He adjusted and he grabbed a tit with each hand as his mouth sucked and licked each nipple. Moving back and forth he moaned and sucked my nipples.
I was going crazy with desire.
I wrapped my arms around his arms. I was panting as my body was reacting when I should be repulsed.
I began to kiss Stran's shoulders and I sucked his neck as we moaned and rocked against each other.
"Fuck me.... " I stuttered. "Please.... fuck... me"
Stran pushed himself up as he unbuttoned his khakis his eyes roamed over my body.
My heavy tits were resting high on my chest. My pregnant belly was high.
I watched Stran's face as he smirked when his fingers hooked my panties. I lifted my hips and the lace fabric slid over my thighs.
I spread my legs and Stran positioned his body between my thighs.
He leaned down and kissed his sister's pregnant belly. Then he kissed each thigh.
He moved his thumbs to my pussy lips. His thumbs spread my hairy pussy lips. I could feel the matted wet hair cling to my skin.
When Stran moved his tongue from my thigh to my clit I moaned and grabbed his hair with both hands.
"Oh God yeeeessss" I moaned as Stran flicked his tongue over my hard clit.
Over and over he licked my clit. Then he sucked my clit and his fingertips began to rim my pussy.
I moaned as a heat wave was building from my core to my pussy. The hot wetness that gushed from my pussy and onto my brother's fingers while my pussy throbbed.
Stran moved his mouth to my pussy and his tongue sucked his pregnant pussy juice.
I released his hair as I panted.
Stran began to kiss my thighs up to my pregnant belly. His hands grabbed my tits as his mouth sucked my nipple hard. His teeth bit my hardened elongated nipple causing me to flinch and arch my back.
Stran spread his legs causing my thighs spread further.
He released my tits. His mouth began to kiss my neck as his hand guided his cock between my pussy lips.
As his thick cock head pushed deeper. I inhaled sharply as my pussy stretched around him.
"Fuck... fuck" Stran grunted "Sara... you're... holy fuck you're tight"
I felt my pussy stretch as he pushed more of his cock deeper. I felt my body reacting as Stran was balls deep. Each thrust made the sticky sloppy sound as his balls smacked against my wet pussy.
I felt my pussy throb around his cock. I felt my creamy pussy juice gushing with each thrust.
Stran fucked me good. Every stroke was solid as the head of his cock stroked my gspot.
I clawed at Stran's shoulders. I wrapped my legs around his. We were panting as Stran thrusted and ground his cock balls deep. His pelvis ground against my hard clit causing a very intense full body orgasm.
My pushy juice was thick, creamy and hot as my pussy squirted.
Stran groaned as his pregnant sister squirted pussy juice onto his stomach and balls.
I felt his cock throb as he grunted. His cock shot his cum deep into my pregnant pussy. As I panted he grunted. He caught his weight as he slid off me.
I had a river of sex juices ran from my pussy. As Stran rolled onto his back we were both panting.
As the cold air hot our sweaty bodies, the smell of sex filled the room.
"Holy fuck sis, oh my God you're amazing" Stran slurred as he sat up.
The doorknob jiggled as Sam tried to get in.
Stran smiled and jumped across the bed and ran to the bathroom.
I covered myself with the blanket just as Sam opened the door.
