He'll take her ass.

"Go bend over the bed," he then told her.

"Oh, alright," she smiled, getting off the bed and turning back to it before leaning forward, planting her hands on the edge. He crawled off of the bed himself, and stood behind her. "Going to fuck my pussy from behind?" she asked.

"Not exactly," he grinned, lining his cock up with her anal entrance instead, and she froze, looking back at him.

"My ass?" she asked, realizing that she wasn't against it, no doubt an effect of his book.

"That's right," he replied, prodding his cock at it, before slowly pushing into her rear.

"Unh..." she groaned, gripping the bedsheets. He was taking it slow enough to avoid hurting her, but it still felt bizarre. After several minutes, he was buried up to the root.

"So tight," he remarked, putting his hands on her ass cheeks, giving her a moment to adjust.

Panting a bit, she looked back at him. "I'm completely under your power, aren't I?"

"What makes you say that?" he smiled as he slowly began to move.

"The fact that I would have never allowed this, but now, here I am, happy to take your shaft up my ass," she gasped out between her moans.

"Fair enough," he replied, still going slow so as to let her adjust before he really went at it. Her anus squeezed down on his manhood as she moaned and kept taking it.

"...if it keeps feeling this good... Then I could get used to this..." she cooed, feeling him speed up. She laid her front down on the bed as he began pounding into her ass.

With her inexperience with taking it up there, and with how tight she was on his cock, it wasn't long before they both hit their peaks. "Oh gods, you're about to make me cum!" she cried out.

"Then I don't have to hold back my own orgasm!" he replied, before groaning as his dick erupted, filling her back door with his semen, and she gave a scream of ecstasy that she muffled with a pillow as an orgasm tore through her as well.

He pulled out, and gave a contented sigh. "I think that's enough for one night," he told Mika as she had her front laid on the bed.

"Y-yeah..."she wheezed. "In that case, I should get dressed and head to bed... Unless you wanted me to join you in yours?" she suggested.

"Great thinking," he replied, helping her up to crawl into the bed, and he got on right behind her.
