With harsh breaths, the two were intertwined with Solus covered by Megatronus' larger form. The black and blood orange Prime growled possessively at the sight of his lover responding to his spike breaching her valve. He always loved hearing her moans each time he thrusted deep into her. Even when he made her overload, she was the most beautiful thing.

Sometimes, they would switch things up. He had masturbated to her more than anyone, and she knew it. Solus would purposefully display herself so he could come around and claim her when she "didn't expect it." It was all fun and games. Until there was one thing he kind of didn't know what to think of.

"Solus, what are you doing?"

The purple and gold femme grinned, "Just thought I'd, mmph, test this new toy I found."

Megatronus raised a brow as she pumped the flexible object into herself leaning up against the wall of her workshop. He then said, "My love, if you wanted to play, all you had to do was ask."

She pulled it out with one end covered in lubricant a little embarrassed. Megatronus noticed it was phallic in shape but double ended.

"You want to try it?"

The question threw him off greatly. A heavy blush hit his features upon recognizing her proposal and couldn't find the words he needed. "I-I, well, I'm not familiar with toys like that. I, uh...what do you propose?"

He peered down at her feeling very weak in the knees as she commanded, "Lay on the table and open your valve for me."

Her workshop table was huge with tools scattered about that were easily knocked off. He crawled on it and she followed. With uncertainty, he let her settle between his legs and opened his valve curious. He shivered when the end she had been working on already lubed up slipped slowly into him. He let the intrusion settle before she started pumping it into him.

The feeling was strange at first but arousing. He felt it stretch his walls and rub across his nodes at a pace that made him give a timid laugh, then it melted to a moan. The slick toy pushed deeper with Solus at the reins. It made his walls ripple and contract. The smoothness made it easier to flow against his insides. He laid back and tried to arch as Solus increased the pace to watch his reaction.

Then she stopped and he looked down his body to see her align herself with her legs over his. She briefly smiled until the exposed end of the toy breached her and made the sweetest noise. Megatronus saw what she intended to do and let her grab his thighs to drag herself onto the remainder until their valves were flush against one another.

Megatronus closed his optics, settling back down again with a wanton gasp as Solus started to pull out and then move back towards him. The toy moved inside him, and he just let her take charge to show him the new experience. His valve folds constantly met her own, exchanging fluids amid their clashes from how much their bodies produced to accommodate the toy. He responded back by copying her. The results were electrifying.

Solus became more demanding and gyrated her hips to snap against him. The toy was pushed harder, deeper and antagonized the nodes that made Megatronus meet her halfway in desperation.

"Look at you, Megatronus," she purred, "taking it like a Prime."

The taunt made Megatronus buck to bounce his valve against hers. The toy was barely visible between them. He sat up to let Solus shorten the space by meeting him until the thrusts stopped and their valves were completely together. Solus didn't let him move, seating herself to torture him in a standstill.

"Solus..."

"Yes, my dear?"

"Please," he all but whimpered when she moved her hips in a circular motion. It made the toy try to move and her valve petals teased his.

Solus seemed to contemplate his plea before suddenly making hard, sharp motions that made both of them grunt. Megatronus welcomed the rough thrusts and laid back down arching. His chassis jolted with each pounding. The toy prodded his deepest sensors that made him grow one step closer to his orgasm building.

Solus' servo held onto the toy once it was mostly in Megatronus and bounced herself on it with a devious agenda. He was too enamored with his filled valve that he didn't mind his lover fucking herself on the toy they shared. Each vibration shook him to his core until his body could take no more.

He cried out and mapped his quivering abdomen plagued by spasms. Solus followed with a slam of her hips to trap the toy among their touching valves. It added an extra motion of pleasure to Megatronus' ravaged form.

Solus pulled herself off and climbed over to him. He kissed her feverishly in the wake of her overload until she moved back a little and a new moan escaped him when the toy began to move. She tried to stuff it entirely in him; Megatronus only encouraged it with a slow roll of his hips. He suddenly bucked when Solus lowered her helm to his leaking valve. Her lips took the head of the toy and pushed it to keep it in him as she also began eating his valve. The deep toy and assault on his valve lips built up his pleasure tenfold. He was all but shouting loudly and spasming hard from her motions.

Megatronus sometimes questioned Solus' tactics in their interface sessions, but she always had a knack for proving his doubts wrong. He had been unsure of this toy. Now, he couldn't get enough of it. He understood why she liked it.

AN: I refuse to believe Megatronus and Solus wouldn't be kinky as shit in their coupling.
