The next morning, Liz woke before I did. My morning wood must have been poking her ass, because she moved her body enough to find a more comfortable place for my cock. While I was dreaming, my hand was still between her big breasts, and her hair partly covered my face.
I think I was dreaming of an older life, where I had my own house, a sweet wife, and a cute little daughter who looked a lot like Lisa Mitchell but wasn’t Black—like Lisa is. Did I mention that her parents (Yolanda and Bobby) are African-American?
That’s when Liz put her hand on my boob-holding arm and gently woke me up. As soon as I approached consciousness, she disentangled our bodies and turned to face me.
“It’s time to get up, Dan. You were smiling; sweet dreams?”
“Being in bed overnight with you is something I will always remember.”
“Me too, Dan. You’re always so sweet.” Liz shook her head, as if to reset herself. “We need to get moving. Let’s go pee and have a quick shower together, dress, and go over to Irene’s for breakfast.”
Liz sounded like she was ticking off a paper checklist. I grinned at her.
“I’m just going hop the fence without putting on yesterday’s clothes, since we will be driving for a while to get to that house they rented.”
An hour later, Liz and I were ready to get into Barry’s small SUV and start our journey. He drove, of course, and Mom was to his right. Liz snuggled against me in the second row, and the droning sound of the tires caused her to drift off quickly. As usual, sleeping Liz made her tiny snore or kitten purr that I loved hearing.
Only a few weeks left, and we’d be over. Liz would still be in high school, while I’d be hours away. I understood why we had to break up. But I didn’t have to like it! Barry must have noticed my gloomy mood when he checked his mirror. He had a brief conversation with Mom, which I couldn’t hear.
I was staring out the side window when my phone buzzed, indicating I’d received a text. It was from Mom?
[MOM] my dear son, i know youre feeling down. i cant imagine - no, i -can- imagine.
[MOM] barry and i are in the place now where i couldnt bear
[MOM] to see him go. you know ive never had a relationship like this before in my life
[MOM] my wish is that you enjoy this 3 dy weekend as a last hurrah. for both of you.
[MOM] its hard to imagine now but you will find anothr woman who makes you happy the way liz has
[MOM] liz & i both want you to enjoy your life espcily these 3 days bvcuz we love you
[MOM] smile at me so i know you got this
[ME] (-: love u 2 mom
I smiled with my face as well. I also made a mental note: teach Mom how to use the “Voice-to-Text” feature on her new phone.
I also reminded myself that no matter where I am, Mom loves me and always will.
Yes, a sappy moment. But also true.
“Liz? We’re here at the house.”
I helped her out of Barry’s SUV.
“Wow, it’s big. That’s the lake out there behind the trees?” Liz was looking all around, surprised by the surroundings.
“That’s right, that’s Lake Allegawissett. This is one of several vacation homes around the shore. What I’m noticing is that none of them seem to be close to us; in case we want to prance around naked, nobody can see us and complain. I hear there’s a deck off the back where you can sunbathe.”
“It amazes me, Dan, that you still find my body interesting.” Liz was shaking her head.
“I don’t find your body interesting.”
“You don’t? Your eyes still follow me around, Dan, even when I’m fully dressed.” Liz sounded uncertain.
“Not interesting. Incredible. Incomparable. Inspiring. English is incapable of illustrating your indescribable beauty.”
Mom overheard me. “Oh, BARF. Try indigestible and insincere. Liz, how often does he talk this way?”
“Irene, he’s always like this. He acts like I’m some kind of magical creature who never even farts.”
“But you are magical!” I protested.
“See what I mean? He’s just trying to pry another blowjob out of me.”
“Is it working?” I asked, grinning stupidly.
“I have to admit, it works. I have trouble saying no to him. Irene, your son has NO shame. He’s just getting by on his good looks and his ... sweetness.”
I watched a shadow seem to cross over Liz’s face, and there was a little choke in her voice. Mom rushed over and hugged Liz.
“Oh, honey, it will be alright. I’m going to be your non-wicked stepmother. It’ll be fun! Let’s go inside and get out of our silly clothes. Dan! Bring in our bags. The Mitchells are already here; that’s their car. Barry, let’s find out which bedroom is ours.”
Liz and I were assigned the “smallest” bedroom, a description I found laughable since the room was about 18 × 21 feet. While I undressed, Liz danced around the room gleefully with her arms spread wide.
“It’s a fucking mansion, Dan! I’m afraid to ask how much the Mitchells are paying to rent this joint.”
“Liz, c’mon. That isn’t our concern, is it?” I was standing there, a little uncomfortable and wanting to go down and be with the others. I folded my arms across my belly. “I’m standing here naked with my dick hanging out, and you’re still dressed. Tell me, are you worried about something?”
“No, Dan. You’re right. Why don’t you unhook my damn bra?” Liz pulled off her shirt and backed towards me. She had no doubts about what would happen; I unfastened the hooks and let the two ends and the shoulder straps fall away. I reached my hands forward and cradled her boobs into my hands. Their weight was in my palms, and my thumbs pushed against her nipples.
“You always hold me like my tits are precious, made of gold.”
“Liz, every part of you is precious,” I murmured. “These are precious, but also fun. Aren’t they?”
“OK, I see your point. I guess I need to finish undressing. That means you have to let go of my boobs, silly boy.”
I grumbled, “If I have to.” A few minutes later, Liz and I were undressed, unpacked, and leaving our bedroom together to go downstairs.
The home’s “great room” was accurately named. It looked like fifty people could stand around in there holding cocktails and chatting. At one end was an immense stone fireplace rising up two stories to the ceiling. Two leather sofas faced each other in the center of the room, each one long enough to seat four or five adults.
The Mitchells shared one couch with Barry and Mom, while we took the opposite. Liz and I were familiar with the Mitchells, as both of us had been babysitters for their daughter Lisa, along with Laura, who was watching the girl this weekend. Today was our first time seeing them naked.
Naked Yolanda Mitchell was not surprising to me. I’d seen her many times, usually wearing casual clothing that clung to her abundant curves. I guessed she was the same height as Liz and carried twenty to forty more pounds of weight, mostly in her thighs and bottom. Her breasts were smaller than Liz’s, with dark chocolate circles around black nipples. The rest of her skin was a lovely milk chocolate color, although she had a few stretch marks from her pregnancy with Lisa about seven years ago.
Her husband, Bobby, was quite tall and thin—suggesting he might have played basketball when he was younger, if he was athletic. I knew he was older, close to age 50, and his close-cropped beard showed lots of gray. He kept his head shaved, and his skin was a similar color to Yolanda’s.
He was blessed with the kind of deep resonant voice that commanded attention, somewhat like the actor James Earl Jones. It was an asset for him, because he worked in courtrooms as a lawyer and sometimes as a temporary commissioner or hearing officer.
I would rather not feed stereotypes, but under his judicial robes or three-piece wool suits, he was well-equipped to dispense justice. Apparently, his “gavel” was as long as mine but thicker. Mom and Barry had seen it several times already when they visited the Mitchell’s home, but we were viewing the two Mitchells naked for the first time. Liz was having trouble keeping her eyes out of his lap.
Yolanda took charge.
“We are just waiting for Leanne and Molly to get here; they are expected to arrive within the next hour. They will be bringing drinks for us, including juice, soda, and alcohol. To eat, Bobby and I brought a bunch of groceries. There aren’t any restaurants or stores nearby, so we’re going to be feeding ourselves.”
Barry raised his hand. “I volunteer Irene to make one of the dinners. She’s a wonderful chef, and I’ve gained fourteen pounds since I’ve been eating her cooking.”
Mom growled at Barry, good-naturedly. “Yeah? You are volunteering ME? Then YOU are scrubbing the pots afterwards, dope.”
Yolanda continued, “When those two arrive, we will go into the kitchen together and make sandwiches. After that, the eight of us will see if we can find ways to entertain ourselves until dinnertime.”
We heard the tolling of some deep bells, imitating the “Big Ben” clock at Westminster in London. I couldn’t believe my ears!
“That’s the DOORBELL?” I cried. “That’s the most pretentious thing I’ve ever heard!” Bobby Mitchell and I guffawed. The rest of them looked mystified until I explained.
The next surprise came when I opened the door. Standing there were Leanne and Molly, as expected, and a third adult, an average-sized man with graying hair and a big smile.
“Let us in, Dan, and I will introduce our guest.”
“Uh, OK, sure.” Caught by surprise, I stammered. Also, I answered the door in my birthday suit, and the way this stranger eyed me was unnerving. I simply stood aside and watched the three of them walk into the giant room. As I expected, Molly spoke first.
“Hi, everybody. Please welcome Ed to our little party. Ed and Leanne are our daughter Laura’s bio-parents. When we get back home, Ed will be spending a few days with her. I will introduce all of you, but I should explain first that we have fully briefed Ed on this weekend’s activities. Wait, before I do that, do you mind, Dan? Show us our bedroom so we can drop our bags and undress. It’s only fair for us to meet all of you while equally naked.”
“Alright, Molly, uh, follow me please.” As we climbed stairs up to the bedroom level, I felt nervous. I was sure that Ed was eyeing my ass, and I blurted out words I shouldn’t have.
“My girlfriend Liz and I have spent a lot of time with Laura, and she never mentioned a father. I always thought Leanne and Molly produced her through spontaneous combustion.”
Thankfully, all three of them laughed, getting me off the hook. I started to apologize, but Ed interrupted me.
“It’s fine, don’t worry about it. Laura and I have a good relationship, but we are geographically separated, so she comes and lives with me for an entire month each year.”
We arrived at the right door, and I asked, “This bedroom was picked for Leanne and Molly. Are they OK if you’re in there with them?”
Leanne answered, “Oh, sure, Ed is welcome. I see the bed is big enough for all three of us.”
