The vaginal kind

The god slammed the spy against a column, her clothes seeming to dissolve around her as Loki used his powers.

Loki hungrily sucked on her large breasts, allowing his own clothes to vanish as he did so. Natasha gasped, her body rapt with pleasure at the god's incredible stimulation.

"Please, I want you inside me," she moaned, her hands frantically caressing Loki's muscular back.

"You might find it is too much for your body to take," he replied, between kisses of her flawless skin. "My father may have made me look Asgardian, but some parts of me are still... Giant."

"I was a Russian spy," grinned Natasha savagely. "I spent years training for this. I can handle it."

Loki looked at her with some surprise. Even under the Mind Stone's influence, he would have expected her to be more cautious when making love to a literal god. He must have found quite an exceptional human.

The god roughly grabbed the blonde's shoulders and spun her round, pressing her hard against the plaster wall. Groaning happily, Natasha spread her stance and arched her back, to allow her master better access to her wet cunt. Placing a hand on her hip, Loki plunged deep into her.

Romanoff let out an involuntarily yell, half pleasure and half pain, as a huge vessel entered her canal. It was bigger than anything she'd ever taken, stretching her to her limit. Even Loki gasped, surprised out how tight, yet fantastically lubricated, she was on the inside. "And here I thought you were the promiscuous one," he grinned, enjoying the stimulation as he sunk his entire twelve-inch length into her. The spy didn't respond, her mind consumed by the sensations coming from her pussy.

Finally Loki buried his entire shaft into his thrall, pausing to savour the incredible feeling of her vagina desperately holding him. Then he pulled two-thirds out, and slammed back into her, eliciting another moan from Black Widow. Again, and again he thrust into her, the woman desperately clutching the wall for support as she was pummeled, her tits squishing against the cold surface. Loki grabbed those beautiful globes as he settled into a rhythm, his other hand pressing on her taut abdominal muscles for leverage. Natasha's moans grew in volume as his pace increased... he was just too big. And even though she could feel him bumping against her cervix, that wasn't her main concern; it was how thick he was, how he seemed to be tearing her pussy apart with every thrust. All in all, he filled her up better than anyone ever had before.

Loki fondled her round, soft bum for a moment, then his hands went back to holding his prey still so he could fuck her properly.

"Yes, oh yes, cum in me master, oh god, oh Loki, OH GOD," moaned Natasha, her body beginning to quiver as she felt an orgasm building.

"Oh god... is... RIGHT!" growled Loki, as he exploded inside her, his powerful cum quickly accumulating and pressing against her walls, filling her up beyond her limit. Natasha screamed with pleasure as she came too, body shuddering under the god's body.

After half a minute of orgasm, Loki finally withdrew from his partner, leaving her to collapse to the floor, cum oozing out between her legs.

"I think I shall have great fun with you, Natasha," grinned the god.
