Tony nodded and slid the condom on and smiled at Steph. “yes Captain.” he teased, kissing her again as he lined himself up. He slid into her easily with a moan, and took his time doing that too. Everything he did seamed so careful and gentle. As if he was as terrified of hurting her, as she was of hurting him.  He’d always been that way, around Pepper, around Natasha, around Steph. So gentle, as if he was afraid that he might hurt them without even realizing it.
