Trisha hurried down the street, sneaking glances behind her. She'd left Edward with Pinako, who was more than capable of taking care of him, but she still found herself worrying. After all, Ed was only two months old, and he had been born prematurely. Three and a half months early, to be exact. He shouldn't even have been born yet. And he was so small...
Trisha slipped into a house, making sure that nobody saw her. She slipped her shoes off by the door. "Albert?" Her voice rang softly in the nearly empty rooms. She stepped forward into the house. "Are you here? It's Trisha."
Footsteps echoed. "Trisha? You're here?" A man with short blond hair, just slightly darker than that of her son and husband's, dark golden eyes, a square, honest face, and a kind smile turned the corner, entering the room. He was wearing a brown suit and a green and yellow striped tie with white socks and brown dress shoes. "Trisha!" She smiled at him. He stumbled awkwardly. "Oh...Um...Do you...um...want anything? Food? A drink? Or just...um..." Trisha laughed, crossing over to put a finger on his lips. "Let's just go upstairs, Albert. We can forego formalities."
Albert blushed an interesting shade of red. "Oh...Of course, Trisha." He took her hand and led her up the stairs, her smiling sweetly the whole time. He paused outside the door to his bedroom. "Are...um...Are you sure that this is...is...um...what you want?" Trisha nodded. "I'm sure."
Blushing, Albert led her into the room. She crossed over to the bed. "Do you, or shall I?" Albert's face was so red that he looked like a tomato. "I...I guess that...I can..." She smiled, turning to him. "Then go ahead."
Albert swallowed, approaching her slowly. He stopped right in front of her, so close that they were practically touching. He leaned forwards slightly. Trisha's eyes were right in front of his, big and a deep, wise, green, shining with hidden red, and patient. Slowly, so slowly, he kissed her. She kissed right back, and slowly, they both grew more passionate, tongues fighting for dominance, and Albert slowly slid her sleeves off, baring her small shoulders. She took his tie in one hand and ripped it off. Albert kicked off his shoes. Trisha's dress slipped lower, revealing the upper half of her breasts. Albert stepped on his socks, pulling them off. Trisha pulled off his jacket, leaving him in a white shirt and his pants.
Their kiss deepened before they broke off to breathe. Trisha's dress slipped down to her stomach, now only covering her legs. Albert pulled it down the rest of the way, and Trisha stepped out of it, now wearing nothing but a pair of black lace panties. She pulled off Albert's shirt, her hands flat against his chest. She pulled down his pants, and he stepped out of them, now only in black boxers.
Suddenly, their lips crashed together again, and Albert rolled him and Trisha onto the bed. He broke off their kiss to look down and admire her. Her petite form, small limbs, and delicate skin were the very definition of beauty. The red gleam in her eyes was proof of her Ishbalan mother, and her skin shone with sweat.
Trisha pulled him back down in another kiss, which he returned gladly. Her fingers found their way under his waistband, and she tugged his boxers down. He kicked them off. His own fingers found their way to the sides of her panties, and he gently slid them off of her perfect body.
His fingers then trailed to her crotch, tangling in her pubic hair. First one, then two, then three fingers slipped inside her, moving and gently stretching, scissoring back and forth, and damn, it felt good. Trisha moaned slightly into their kiss. Then he pulled out, breaking their kiss.
Trisha reached for his erection, running her fingers down it gently, sending shivers down Albert's body. Her fingers skillfully danced across it, and he just knew that he wasn't going to last long. She stopped just before, and laid back, her opening clearly visible. He gently moved down, entering her slowly. He began to move back and forth slowly, letting her get used to the feeling, before starting to move faster and faster. Trisha clung onto him, moving her hips in time with his thrusts. Her little cries turned him on even more, and he started to move faster and harder, lifting them up and slamming them back against the bed with every thrust. He cried out as hot cum spilled from his erection, filling little Trisha up. She followed suit moments later.
Finally, spent, they laid next to each other, bodies covered in sweat, neither wearing anything. They shared one last kiss, before Trisha got up, showered, got dressed, and left to get her son and go home.
As luck would have it, Van Hohenheim came home the next day and made love to his wife. He had been gone for a month.
Trisha Elric realized that she was pregnant almost a week later. Hohenheim was ecstatic. He loved Edward so much, and having another child would be amazing.
When the child was born, Trisha knew instantly that he was not Hohenheim's son. He looked exactly like his father. It was a good thing that Albert and Hohenheim looked similar. She could pass off the darker hair as being a variation of Hohenheim's, and the eyes weren't very different than Ed's...
She named the boy Alphonse, in honor of his father, a man who had come through town and stayed for a week, and that Trisha had had both an affair and a son with, and who didn't even know that he had a son.
She never told anybody about her affair. She passed Alphonse off as Hohenheim's son, and everybody, including Hohenheim and Albert, was fooled. She brought her secret to her grave.
None of this was based on experience. I wrote this based completely off of other people's books. I apologize if it is unrealistic or poorly written. I have never experienced this, and have never seen it. So again, I apologize for my poor writing.
