Some people have sometimes thought about what it would be like, but few are strong enough to admit they eventually slept with someone with whom they had a prior close relationship. I am one of those men.
I had no warning about what would lie ahead of me in the near future when I came home from work one evening. My girlfriend planned to attend a charity benefit that she'd nagged me for weeks to go with her, and I was already running late. I don't mind helping important causes, but I can't sometimes help but wonder if Morgan is more interested in being seen by the "right" people to help her up the career ladder than sincerely caring about the specific charities.
I knew something was amiss when she was already dressed for the benefit when I walked in the door. In our entire time together, Morgan was NEVER ready to go anywhere before I, but she still looked like the stunning former beauty queen I'd fallen for in high school.
"Let me get a quick shower," I said. "I'll be ready in twenty minutes."
She shook her head. "Don't bother; I'm going to handle tonight alone."
"Wait...what? You've been busting my balls for weeks to go with you, and now I have to stay home?"
"It's not that simple. We have a surprise tenant. Since I'm already listed in tonight's program, you can entertain her."
"Tenant? Her?"
"Chelsea. She's moving in with us to be closer to her college."
"Your little sister's already in college? I remember when she was just starting fourth grade."
Morgan smiled. "She's looking forward to seeing her 'surrogate big brother'."
"Maybe hanging out at home isn't such a bad idea. That little girl and I have some serious catching up to do."
"Admit it, Tom; you didn't want to go out in the first place, and my sister's hardly the little girl you remember."
"Really?"
"I think you were the only guy besides Dad who was ever decent to Chelsea in her entire life."
"Well, yeah; she's the baby sister I never had. Someone has to look out for her, probably more now that she's becoming a woman."
"Before you go into overprotective big brother mode, she's a virgin and not seeing anyone."
"Uhhh...too much information?"
"No raiding the liquor cabinet either, mister. She's only nineteen."
"Yes, Mother," I replied with an eye roll.
Morgan gave me a kiss. "Keep her entertained and there may be a little something in it for you later."
I squeezed her firm ass cheeks. "Mmm, baby, I'll be waiting in bed naked and hard. It's not like we have much fun in the bedroom these days."
She pulled away my hands and turned to leave. "Behave. Go say hi to Chelsea, and I'll see you later."

The sounds of music and drawers and closets closing in the guest room filled my ears after coming upstairs. Despite what Morgan told me earlier, I still expected to see a shy, chubby girl with glasses and a mouthful of metal when I appeared in her doorway.
Instead, I was treated to the vision of a young woman at least five feet tall with shimmering blonde hair to her shoulders. Chelsea's a bit more curvy than what passes for acceptable in our society, but everything settled into a perfect 34D chest like her sister's, voluptuous hips, and a beautifully rounded ass. The only difference between both sisters was that Morgan's tits were "store bought" while Chelsea's were courtesy of nature.
"Do I know you, miss?" I teasingly asked.
Chelsea turned and leaped into my arms. "Tommy!"
I laughed and gave her a tight hug. "Hey, baby girl."
"'Baby girl' my ass," she snorted and removed herself from my grasp. "I just turned nineteen and in college."
"I've been informed as to such; that and you're going to be living with me and your sister for a while. I'm not sure if I can handle two beautiful women under the same roof."
"Oh, stop it! I don't know what you did to her the last ten years, Tommy, but it's a breath of fresh air to know Morgan's no longer the self-absorbed bitch I dealt with growing up."
"There's an eight-year age difference between you two, Chels. Maybe she wanted a baby brother and resented having another girl in the house."
"It still didn't excuse her calling me Chelly the Four-Eyed Hippo, making fun of my braces, talking shit about me never getting a boyfriend because I was so hideous, and acted like she was embarrassed to be seen with me in public. Not every girl grows up winning one pageant after another and having every boy in town fawning over her while some of us remained practically invisible." She then laughed. "I did get some justice, though; my hair stood blonde and these boobs grew on their own while Morgan's hair darkened and she had to get implants."
"You became a beauty," I assured her.
"You've always been way too nice to me, Tommy. I may be young, but still smart enough to know the world's Chelseas rarely get edges over Morgan types."
"Don't be so sure. You'll have plenty of time to meet the right guy. Concentrate on your education first."
"Now you really sound like a big brother!"
"I resumed where I left off because I care about you."
She stood on tiptoe and pecked my cheek. "You're so cute. I thought you were going with Morgan."
"Change of plans. She didn't want you to be lonely the first night in your new home."
"Let me guess; you weren't thrilled with the idea of dressing up to eat rubber chicken at some boring charity dinner anyway."
"You know me well. My idea of a wild night is kicking back in clothes your sister hates seeing me wear, not showering, eating cold pizza, and rotting out my brain in front of the TV."
"I never took you for the homebody type, Tommy."
"Thank your sister for dragging my ass almost everywhere the whole time we've been together. I'm not complaining, but some 'me time' is welcome on occasion. I'm going to sound like a bad boyfriend for saying this, but I was actually relieved when she told me to stay home and keep you company."
"I don't think you're a jerk at all. A little down time alone never hurt anyone."
"Speaking of which, are you in the mood to hang out downstairs? I planned on popping in one of my dude movies Morgan can't stand."
"Yeah, I've finished unpacking and could use a break with one of my favorite people."

Chelsea went upstairs to prepare for bed after the movie ended. I still hadn't showered since coming home from work, and Morgan was due home in half an hour.
I turned the bathroom door knob to open it when the sight of a topless Chelsea made me freeze in my tracks.
She screamed and quickly covered her bare breasts with a towel. "Damn it, Tommy!"
"Oh my God," I gasped in embarrassment and backed away. "I am SO sorry!"
"You better not have walked in on purpose! It's not funny!"
"Who's laughing? I swear, Chels, I didn't know you were in here."
"Try knocking next time, dumb ass."
