Theta.

Ushas stood in the small white bikini, her smile wide as Theta tried to wrap his head around what had just happened. That dream had seemed to real, so solid... But now he was here, with Ushas.

"Well? Aren't you going to say anything?" The time-lady asked, cocking an eyebrow, glancing down at herself, then back up at him. "I know, I know, we shouldn't really... But don't you miss it? We used to have so much fun back in the academy. You were always my favorite, you know that, don't you?" She asked, walking towards him.

Theta raised an eyebrow. "What does that mean?" He asked, the Time Lady was now standing over the Time Lord, towering over his sitting figure, smirking down at him.

Theta shook his head. "Ush... We can't do this, I'm sorry, but I'm just not gonna do that to Kosh..." He was cut off, by Ushas' finger moving to his lips. "Don't worry so much, Theta." She protested. "Kosh won't have to find out."

After being rescued by Morty and Ushas, Koschei and Ushas had fallen into a rather powerful, romantic relationship. All, Theta thought, had been going well until five days ago, when Ushas had first began to flirt with him.

At first, Theta thought it was just some strange joke, but then it got more and more blatant. Every time Koschei had turned his back, there she was, her hand on his junk, her lips in his ear, Theta had never been so uncomfortable, even counting his time in the Dalek prison camp.

Now with her standing over him, almost completely nude, he was finding it hard to fight back against her, and she knew it too.

She began to slowly rub her hands along her body, tracing her finger tips along her curves and along the strings that made up her bikini. "Don't tell me you'd prefer Morty's new feminine body to mine? Don't you remember him being that fat little boy in the academy... Whereas me... I've always been 100% Time Lady." She winked, her exploration of her body had moved her bikini, letting the smallest trace of her areola to be seen.

Ushas smirked, knowing there wasn't a single way Theta could resist her powers of seduction, how could he? Look at her! She was gorgeous, the greatest example of a Time Lady ever to grace Gallifrey's crust.

Theta felt himself weakening to her, felt his members slowly expanding in his pants. He closed his eyes, tried to think of anything else, tried to remember the mathematical equation that allowed their transpacetial engineering to be possible, but couldn't.

Finally he opened his eyes and let out a small moan, he was now, face-to-face with her large, bare breasts. The look on Ushas' face told Theta everything he needed to know, he had lost the battle of the wills... And she was ready to claim her prize.

Theta groaned as the large boobed woman, dropped her bikini, letting her nude body be revealed to him for the first time.

Ushas stood there, allowing him to take in her goddess-like form, her neatly shaven pussy lips dripping with juice in anticipation of the fucking she was about to receive from the Time Lord.

The Time Lady lowered herself to her knees, unzipping Theta's pants and yanked them down with one tug. Theta's two hard and throbbing dicks greeted her, causing her to moan out in delight.

Ushas, took her mouth to one of Theta's large cocks, sucking him off with vigor and enthusiasm, while with her hands she massaged his balls and stroked his other cock. The Time Lady gagged on Theta's cock while her tongue lapped up his pre-cum that was dripping out of his dick.

Then, Ushas raised herself from the floor, stroking Theta's cock with her left hand, while she held his balls in her right hand. Theta was already so horney that he could no longer think of why he was trying to protest this in the first place.

Ushas turned and bent over, letting Theta get a good view of her large, round ass, and dripping pussy lips. She spread her cheeks with her hands and looked back at the Time Lord. "Come and fuck me, Theta, just like you used to... Just like I know you want to again."

Theta stood and lined his large lower cock up with her pussy lips, he thrust his cock as far as he could into her, the tip of his cock bumping her cervix and making her womb jump from the feeling of his cock rubbing against it. His upper cock was squeezed between her ass cheeks, being hotdogged by her large ass.

Ushas moaned and groaned, loving the feel of his cock in her pussy. "So nice and tight, right Theta? You always did give me such good dick!"

Theta fucked his cock as deep as he could into her pussy, feeling it hit her G-spot and making him even hornier than he was already. He was enjoying every second of this, and he couldn't help it.

The Time Lady reached around and grabbed his upper cock, stroking it while it was hotdogging her, stroking him for a moment and then she moved her hand lower down his body and grabbed his balls. "So full and soft and warm," she moaned.

Ushas moved her body, pressing herself into Theta, moving with his rhythm. Theta brought his hands up to her breasts, kneading them like dough. Ushas moaned, a sound of pure, unrestrained delight, feeling his fingers on her. Then she moved her hands back to his cock and rubbed his head, before suddenly moving forwards and twisting round.

She was now on her knees, his cocks both buried in her throat.

"OH RASSILON!" Theta shouted out, as he suddenly felt both his cock being engulfed at once by the talented Time Lady.

Theta's eyes were closed, his head hung back in pure pleasure, as he felt Ushas' hand on his abdomen, his cocks still in her mouth. She pushed on him and he toppled over backward, landing on the bed.

Ushas then did something that boggled Theta's mind. Still with both his cock deep within her throat, Ushas moved. Twisting around him, so she was no longer kneeling in front of him while he lay on the bed, but was now laying on top of him, in a 69 position.

The twisting sensation nearly pushed Theta over the edge, nearly caused him to cum inside her throat then and there. But he managed to hold himself steady.

The pleasant sight and smell of her pussy lips moving to his mouth gave him something to focus on, other than his own pleasure, and he began to dig into her. Lapping and eating her out like a man possessed.

The Time Lady shoved his two cocks balls deep into her mouth, holding them inside her throat for as long as she could hold her breath, squeezing their shafts with her throat before pulling up and gasping for air, starting to jack him off as enormous amounts of drool poured from her mouth coating Theta's cock, balls, and almost entire lower half in her spit.

Her moans and sounds of pure ecstasy filled the room as Theta gave her the most thorough cunnilingus she had ever been lucky enough to experience.

She thought of how many times she could cuckold Koschei, how many times she could convince Theta to do this, to betray his best friend in such a permanent way, the idea causing her to shiver in an intense orgasm, while she jacked away on his two cocks.

Ushas had long ago learned how to be in control, and she learned how to stay focused as she continued to use her mouth to pleasure him, licking the tips of his cock, tasting his pre, knowing he was moments away from exploding onto her.

"Do it, give me your betrayal." She told Theta. "GIVE ME YOUR SEED!"

Ushas' lips engulfed his twin cocks again, as he began to pump his load up and into her hungry, cheating, slutty mouth.

Slowly his orgasm died down, and she pulled away, opening her mouth to show him the contents her had just placed there, before swallowing the lot...

"G'night Theta... See you in the morning." She said, winking, and after grabbing her white bikini from off the floor... left. Leaving Theta alone to come to terms with what he'd just done.
