Mom kissed me deeply as she slid her hand inside the waistband of my shorts. Her hand deftly found my growing cock and began to stroke, getting me almost to the point of a full erection.
"Is there anything specific you want to see?" Mom asked Stacy in between kisses.
"I want to see it all. Everything you would normally do if I wasn't here," my sister responded from her chair in the corner.
"Everything? You think you can handle seeing everything your brother does with me?"
"I'm a big girl. I can take it."
Mom was pulling down my shorts during this exchange, freeing my cock. Stacy let out a slight gasp as she saw how big it was, but managed to look nonchalant about the situation.
Mom stroked me absentmindedly as she stared at Stacy, who returned her gaze with equal force.
"You can take it? You can handle seeing your mother choke down your brother's big cock? Watching him shoot his big, creamy load down mommy's throat?"
"Of course," responded Stacy, visibly beginning to squirm in her seat.
"You can handle watching him pump my pussy full of cum? That won't freak you out?"
"... no... not at all."
Stacy's hand was beginning to creep between her legs at this point.
"And if you watched your brother fuck me in the ass? It's the ultimate taboo for a mother and son." Mom wore an evil grin, knowing exactly how she was teasing Stacy.
"Oh... oh... I..."
"Maybe that would be too much for you. We can skip it."
"NO! I mean... no, it wouldn't be too much. Please... please show me. I want to see everything." Stacy's hand was fully in her pants now, shamelessly going to work on her clit.
"Well, let's not keep her waiting," Mom said, finally turning to address me after stroking me now for quite some time. "Sit," she instructed me, giving me a light shove down onto the bed. My stiff cock bounced in front of her face, and she gave it a long, sensual lick from base to head.
"First, Stacy, I'm going to show you how your brother likes to have his cock sucked. He likes it slow... sloppy... deep."
Mom stared into my eyes as she said this, lowering her mouth to take my head inside of her soft, warm lips. I let out an involuntary moan as her lips moved down my shaft.
"Isn't he big?" Mom asked Stacy as she pulled her mouth off and started to stroke me. "I've been trying to take him all the way down, but it's so hard. I think maybe... maybe for this special occasion I can do it. Want to see me try?"
Stacy said nothing, but nodded her head vigorously.
"Mom, you don't-... oh, fuck... oh, fuck yes Mom!"
I was going to tell Mom that she didn't have to try deepthroating me again, but she got to work before I could stop her. She took me as deep as her usual stopping point, paused, and then started trying to force herself further down. Soon she pulled back off, breathless.
"Sorry baby, not that time. I can do it though." Dutifully she returned to work, pushing herself down fast and hard. I couldn't believe how forcefully she was working me with her throat, but I loved it.
"Mmm... mmf... ungh...mmm," Mom grunted incoherently as she endeavored to go all the way down to my balls.
"Do it, Mom. I want to see you take it all!" Stacy encouraged from her chair. "Do it for me."
Mom paused in her sucking briefly, and turned to gaze lustfully at Stacy. She composed herself with a deep breath, and then attacked once again. This time, after all those failed attempts at deepthroating her son's cock... success.
I couldn't believe the feeling when my cock finally broke through her throat barrier. Her lips were suddenly around the base my hard cock as her eyes bulged in panic at the position she now found her in. It was clear that her success was a shock even to her. I heard Stacy gasp, equally surprised, from the corner.
Mom grunted as she tried to just breathe and stay calm. Her hands gripped my thighs forcefully as she attempted to relax and keep me in her throat. She managed to make eye contact with me as she choked on cock, her eyes betraying her mix of shock and uncertainty.
After a few seconds, it was too much for her. She ripped herself off of my cock, a large amount of spit falling between us onto the floor, as she sputtered and gasped for air.
"Oh... fuck, I did it! I deepthroated you!"
"Sure did, Mom. That felt amazing. You okay?" Mom was gasping to catch her breath.
"I... I'm ok... I'll keep practicing so I can do it more but... wow. Maybe let's just fuck now?"
"Yes," Stacy chimed in from where she was still sitting and pleasuring herself. "I want to see how you guys fuck."
I stood up from the bed, my cock glistening with Mom's spit as I pulled her up to her feet. She was still in her robe, but I quickly removed it and pushed her firmly onto the bed, lying on her back. Her pussy was visibly wet in anticipation of being penetrated.
I straddled her on the bed, keeping eye contact with Stacy the whole time. She glanced from my face, to my cock, to Mom, and back again in intervals of a few seconds, all the while keeping up the attack on her clit. Her pants were now completely down, and I could see her beautiful trimmed pussy on display.
With the head of my cock at Mom's dripping pussy, I locked eyes with Stacy.
"Are you ready, sis? You want to see this?"
"Put it in. Put it in her, please, I want to see."
