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.
