Chapter 5

The big busted mom giggled as she nearly fell over maneuvering it onto the box spring. Once in place she fell back onto the mattress with a big SIGH.

“My God this bed is a monster,” she said, crawling to the center of the mattress.

“I still can’t believe we got it in here.” Alex said.

Monica padded the bed beside her. “Come rest with me for a minute.”

“Sounds good to me.” Alex said, crawling onto the mattress and sprawling out onto his back.

Monica nuzzled close, draping an arm and legs across him. Alex let out a tired breath and his mom lifted her head to look at him.

“You okay?” She asked.

“Yeah, why?”

She had a playful smile. “Just making sure. Last time we were like this you were sprouting quite the piss hard-on,” she said with a little grin.

“Jeez, Mom,” he blushed.

“Well, you were…then you were trying to act like I couldn’t see it.”

“I’m sorry…it just happens.”

Monica burst out giggling. “I’m just teasing you, sweetheart. It really doesn’t bother me. 

Erections are a natural function of a boy’s body and remember, we’re roommates now, so I don’t want you to feel like you have to hide it every time it happens okay?”

Alex nodded, still a tad embarrassed.

“Hey…” Monica said, gazing down at him with those brilliant green eyes. 

“I mean it…we’re sharing a bedroom, sweetie, which means we’re gonna see things. Things that we probably wouldn’t normally see. Just promise me you won’t be embarrassed when it happens okay?”

Alex nodded with a smile. “Okay.”

“Good, cuz if you do get embarrassed…I’m gonna TICKLE you,” she said, then dug into her son’s ribs.

Alex laughed and flopped around, trying to escape his mom’s fingers.

Monica pulled him back down onto his back, then threw her leg across his lap and mounted him. 

Alex thrust his hips over and over, trying to buck her off.

Monica giggled as she rode his teenaged loins. Her big mature tits jumped up and down under the tube top. The hem crept down and her jugs nearly spilt out.

Alex stopped bucking and had an astounded smile. “Mom, you’re gonna lose your top.”

She didn’t pull it up, but grabbed his hands and pinned them back against the mattress. 

“That IS a possibility.”

With his Mom leaning forward Alex was exposed to an obscene amount of cleavage. 

“What’s that supposed to mean?”

Monica gazed down into his eyes with a quirky little smile. 

“This is my bedroom too, remember? So if my boobs fall out of my top while I’m tickling you…then I guess you’re just gonna have to deal with it.”

“Deal with this,” he said, quickly rolling his mom over onto her back.

Monica let out a playful SCREAM and found her son on top of her. She immediately brought her naked legs up and wrapped them around him.

When they both stopped giggling they found themselves sharing a prolonged gaze. The seeds of forbidden desire were just starting to sprout and they were both feeling it.

Being this close and flirty with his own voluptuous middle-aged mom was an absolute rush for young Alex.

For Monica, having her own innocent teenaged son between her legs was absolutely exhilarating.

Alex slowly pried himself out from between his mom’s legs and off the bed, trying his best to conceal his growing erection.

 “I guess we should get back to work huh?”

Monica rose up, resting on one elbow and stared at him with a naughty little smile.

 “Get back here,” she said softly, beckoning him with her finger.

Alex gazed at her for a second. Her long luscious legs were stretched out and her tube top pulled nearly off, revealing the tops of her enormous breasts.

Alex crawled back onto the mattress and Monica guided him back down between her silky legs. 

Again she threw them up around him, this time criss-crossing her ankles together above his ass, locking him in.

She could feel the obvious bulge resting against her. 

“We’re not gonna be embarrassed, remember?”

“Yeah, yeah…I remember.” Alex said, still somewhat timidly.

“You’re not gonna try and hide it anymore, right?”

Alex nodded.

Monica giggled, lifted her head and planted a quick kiss on his lips “Thank you,” she whispered, then unlocked her legs and watched the cute teen squirm away.

Before noon Monica and Alex were able to get most of her things moved out of the master bedroom, but their new bedroom was now a disorganized mess.

Alex came down with one of the final boxes from his mom’s closet. “Hey Mom, what’s this? It’s a box that says ‘honeymoon’ on it.”

Alex handed her the box. Monica placed it on the bed and opened it. “Oh, these are things from the honeymoon your father and I took to Mexico.”

“Oh, like stuff you guys bought there?”

“Yup” she answered, thumbing through the items.

“That looks like a bikini.” Alex said.

Monica lifted a skimpy pink string bikini from the box.

 “It is…it’s the one I wore on the beach practically the entire time we were down there.”

Alex stared at the tiny patches of fabric. “No way that thing’s a bikini,” he said jokingly.

“Do I have to prove it?”

Alex knew his answer, but he didn’t wanna seem too excited. “If you want to, I guess.”

“Well if I try it on I’m gonna have to do it before your sister gets home. It’s not the kinda thing I’d want her seeing me in.”

“I was just kidding, Mom. You don’t really have to. Alex said, a little surprised that his Mom took his joke so seriously.

“No, I don’t mind. I’ve been wanting to try it on again anyway. Just do me a favor and lower the shades. We don’t need the neighbors seeing me parade around in this thing.” Monica said with a giggle.

Alex’s heart was racing. “Naw, I guess that wouldn’t be good.”

Monica carried the bikini out of the room. 

“Back in a few minutes.”

It was the longest few minutes of Alex’s life. Finally, he heard his mom stepping up the hallway.

“Just remember, I’m a little chunkier now than I was at 18,” he heard his mom say as she approached.

As Monica rounded the corner and into the bedroom, Alex literally felt his mouth fall open.

The skimpy two-piece barely covered her. Huge rolls of tit-flesh were spilling out everywhere. 

The bikini fit snug around her curvaceous middle-aged body and the bottoms were so tight that they literally molded around the grooves of her snatch. 

Her dark tan against the pink nylon fabric looked stunning.

With one leg cocked out in front of her, Monica placed her hands on her hips and fed her son a playful smile. 

“Well, what do you think?”

Alex could hardly speak. “I see now why you wanted to close the shades.”
