From behind.

"Go up to the wall and put your hands on it, stick your butt out," he told her.

"Oh... Sure..." she replied, standing up, her ample curves giving a small jiggle as she did, and she walked right to the wall, bending forward and planting her hands against said wall. She looked back at him, pink in the face, and asked, "You... You're about to have sex with me, aren't you?"

"Yes, I am," he said, approaching her from behind and planting a hand on her ass. He stroked his cock a few more times to ensure maximum hardness, and then lined it up as she turned her gaze back to the wall.

Then he pushed right into her waiting folds. "Ah!" she cried, her tight entrance parting to accept Kon's borrowed shaft. He placed his hands on her ass, and pushed until he bottomed out.

"How are you feeling?" he asked her.

"It... It hurts a little, but it feels good..." she admitted.

"Right, I'll be gentle," he replied, starting slow for her.

"Unh..." she moaned as her pussy tightened and she pressed back against him unconsciously. "This feels great..." she mumbled.

"Let me know what the pain has faded," Kon coaxed her as he gripped her waist and continued to pump his hips into her. She bit her lip and nodded, before just focusing on the feel of his dick in her. He very gradually increased his pace, letting her get used to it all, and after about five minutes of keeping this up, she nodded in confirmation that she was ready.

He smiled, and began to pound into her, getting a yelp of pleasure from her. He leaned forward, sliding his hands up her torso, and then over her tits. "Ah... Ichigo..." she cooed.

"..." he decided to take that wrong name in stride, knowing she had likely fantasized about Ichigo doing this sort of thing with her, and seeing as he was in Ichigo's body, it was not a slip up he intended to hold against her.

He played with her boobs and groaned as he kept pumping into her. Soon enough, his dick throbbed, and he grunted as his orgasm hit, causing his seed to spill forth. "Ahhh!" Orihime cried out as she came as well, her eyes wide open, and her tongue lolling out. Kon panted a bit, before he grinned and pulled out.

"That was great," he chuckled, and she nodded in embarrassed agreement.
