A/N: Another pairing idea from Yodana.

Sentinel cursed and slammed his servo into the side of the Transwarp gate before turning away. He couldn’t believe the traitor, Wasp, had slipped right through his fingers. He was a Prime! Wasp was a boot camp washout! He was never going to hear the end of this from Ultra Magnus or his subordinates. He was going to make the runt pay for this humiliation. Pebbles crunching under a foot made him stop dead in his tracks.

Turning around, Sentinel growled, “Back to face me you scu--”

Wasp would have been a welcome sight compared to what greeted his vision. A space barnacle, monstrous in size and covered with numerous magenta eyes, tentacles sprouting from its shoulders, back, and abdomen, was staring at him with a curious expression. Tensing from fear, his processor raced with bombarding messages of fight or flee. He chose the latter. He didn’t want to touch that disgusting, organic, monstrosity. A tendril shot out, snagging his pede, tripping him, and he collapsed to the ground, face slamming into the dusty terrain, fingers scrabbling for leverage as he was tugged back.

“No! No! Help! This is Sentinel Prime! I need backup! Now!” Sentinel shouted over his com link.

Luck really wasn’t on his side this day. There was interference with the signal, leaving him trapped with the monster. Extending his lance, he jabbed at the tendril latched to his pede, optics widening in horror when the blow left little more than a scratch. The weapon in his grip was knocked away by another tentacle, and he quickly used his shield to block more tendrils from wrapping around his neck and chassis, beating them off until he was left panting from exhaustion. There were just too many, and within minutes the shield was pried from his fingers and tossed aside. Tendrils coiled around his arms and legs, lifting his thrashing body into the air, and inch by dreaded inch he drew nearer to the space barnacle. The creature’s mouth opened, and a long, slimy tongue reached out to lave his face and antennae.

“Ungh! Disgusting! Stop!” Sentinel grunted, nearly purging his fueling tanks as copious amounts of drool trickled down his faceplates.

If the creature understood his words, it chose to ignore him, tongue trailing lower to slide over his pelvic armor, probing the seams, searching for a way to unlatch the obstacle to the intimate areas hidden beneath. Writhing in a frenzy of panic, Sentinel screamed as loud as his vocalizer would allow, praying that someone would hear him and come to his rescue.

“Pretty…aft…” the creature cooed, voice deep and gravelly, tendrils obsessively massaging the Prime’s backside.

He never knew such creatures were capable of communication, but, even with advanced technology and the brightest processors in the universe on Cybertron, there was still a lot of mystery surrounding space barnacles.

“Let me go!” Sentinel snarled. “Just let me go…and I won’t report you. You can go on your merry way, and you won’t end up on a dissection table back at Cybertron.” He ground his dentals as the tendrils continued probing between his stretched legs. “Are you listening to me you vile organic?!”

“Pretty…aft…” the creature cooed again. “Want…pretty…aft…”

Sentinel’s optics twitched. This creature seemed to only have one thing on its mind: mating with him. It was a horrible concept he only thought possible in his worst nightmares, but his nightmare was obviously becoming a reality when a massive shaft emerged from between the creature’s legs. The tips on the tendrils folded back, revealing swollen heads glistening with beads of white liquid. A small amount of oil rose back up, and he hacked it out, shaking violently as the tentacles rubbed over his body, leaving behind trails of sticky fluid.

“Please, please, please, please, please, just let me go!” Sentinel sobbed.

An engorged tentacle suddenly jammed into his mouth, cutting off his pleas. He gagged and swung his helm around, trying to free himself of the offensive appendage, but it only crammed deeper down his throat. He clamped his dentals hard around the tentacle, and he let out a muffled cry of pain as his dentals cracked under the pressure, instantly letting go. This creature was tough, and biting wasn’t going to help him get free. Bitter fluid coated his glossa, and he gagged, causing the creature to mewl as the prime’s throat clenched around the invading tendril. Oily tears dribbled down his cheeks as the tendrils exploring his groin and aft pried at his paneling, ripping the metal free, creating a stinging wave of agony.

“Smell…nice…want…to…taste,” the creature murmured, tongue dipping lower past the Prime’s exposed spike, straight to the prim little valve.

‘No! No! Don’t put your filthy tongue in there!’ Sentinel’s mind screamed.

He let out strangled scream as the creature’s tongue teased the lining of his valve before shoving inside, swirling around his wiring, plunging in and out in rapid strokes, savoring his sweet taste. The tentacle in his mouth expanded and liquid bust from the tip, excess trickling down his chin as the spent tendril pulled out.

“Ngh! Gross! Gross! You slagger!” Sentinel roared, spitting up as much of the foul fluid as he could. “How dare you! I’ll make you suffer for th--mmphh!!”

Three more tendrils jammed into his mouth, thrusting hard and fast, sending a twinge through his overstretched jaw. The tongue ravishing his valve eased out, replaced with a tendril, quickly wriggling inside, making him quiver and groan from the mixed pleasure and pain of having his opening repeatedly slammed into, giving him no time to adjust. His body stiffened as a second then a third and then a fourth tentacle were forced into him, valve throbbing when ten more tendrils joined in. The three tendrils in his mouth spurted and pulled away.

“Ungh! Ahh! Stop! Ngh! Fragger!” Sentinel wailed, spitting in revulsion. He shrieked when two more tentacles jammed up his valve. “No! N--No more! I’m going to burst!”

“Want…more…” the creature growled, bringing Sentinel closer until the Prime was flush against its chest.

“OH NO! NO! NO! NO!” Sentinel shouted as the tip of the creature’s thick shaft touched his exhaust port.

“Want…pretty…aft…” the creature mewled, slowly lowering the Prime.

A shrill scream laced with static emitted from Sentinel as he was impaled. His body was stuffed, nearly on the way to the breaking point. Oil and lubricant seeped for his valve and port mixed with the fluid trickling from the tentacles and shaft, soothing his abused internal wiring. A warm tingling spread through his groin and aft, spike swelling from pleasure. He jerked and whined as a tendril coiled around his length, pumping erratically.

“Ah…ahh…aha!” Sentinel yelled, flaying in the creature’s hold. “S--Stop! F--Fragger! No more! No more! Please! Oh Primus! Oh Primus! I’m…ngh…going to explode!”

The creature ignored him and continued to ruthlessly pound into him, shoving three tentacles into his stuffed exhaust port. When the space barnacle leaned in to suck and lick his antennae, he overloaded, crying to Primus and letting out every curse he knew as his body convulsed in bliss. The tightening of Sentinel’s valve and port made the creature howl, flooding the prime’s internals and drenching his faceplates and chassis.

“F--Fragger…y--you’ll…p--pay…f--for…t--this,” Sentinel snarled, darkness overtaking his optics as he fell into recharge.

Unmoved by Sentinel’s threat, the space barnacle dropped the Prime, leaving the mech alone and covered in fluids.
