Watching mom and my sister make love was like being in an incredibly sensual private erotic theatre. The way each devoured the other's pussy was on a level I hadn't seen in any movie. Mom's tongue practically bored into the soaking wet, semen filled pussy I'd just fucked, gathering scoopfuls of my cum before swilling around her mouth and swallowing.
At one point, with white creamy bubbles between her lips, she even smiled at me and blew a cheeky kiss.
Alice was insatiable too, spreading open mom's gaping wide pussy hole so she could lick around the inside. When my sister focused on her clitoris, I shuffled over and prised mom's ass cheeks apart.
"You just raised your ass higher, mom."
"So that you can lick my taboo hole better, son."
Rimming mom's anal whorl while Alice licked and sucked her clitoris was the head therapy I needed. My nervousness about my sister joining our relationship vanished, god knows the girl had my semen bloating her womb.
We serviced mom so well, her orgasm was an intense spike so high I thought the cabin might shake loose.
"Can you fuck me while Alice and I continue licking each other please, Simon?"
"My cock is hard again just from watching you both, so why not?"
I'd taken a weekender pill after fucking Alice the first time, My full participation in what seemed likely to become a multi-day orgy felt important. When I slid my cock deep inside mom's soft, warm pussy, she shuddered adding to an already rapturous orgasm on the end of my sister's tongue and lips.
"Alice is licking my ball's, mom."
"She's a good girl. Naughty and slutty, but very nice."
"Say's the lady sandwiched between the kids she raised."
Alice's comment might have gone one of two ways. Had it been made a day prior, mom might have broken down, but now, she raised herself up enough to get both hands onto my sister's swollen pussy lips, slapping them gently, making a sloppy noise.
Mom laughed the comment off, shrugged her hair backwards and plowed Alice's cunt with both hands for a minute before splaying her puffy lips apart. I watched my fiancee rub Alice's clitoris with two fingers in a circular motion, eliciting an almost violent response when my sister's ass raised up and thumped hard off the wooden floorboards repeatedly.
"It's too much mom. I'll squirt everywhere."
"Stop being sassy, then."
"Sorry, please be gentle."
Mom dipped her head back down between Alice's legs to lick a pussy that almost appeared to be humming. From the desperate tone of Alice's loud moaning, I knew when mom was sucking and tonguing her clitoris.
I clenched my fingers into Claire's ass cheeks, steadying her so I could fuck my fiancee deep and quickly. My sister sucked my balls one after the other into her mouth, bathing each until a powerful orgasm twitching inside me became obvious on her tongue.
"He's about to shoot his load inside you, mom."
"Do you need me to move away after Simon empties his seed, baby?"
"Nope. I've got this."
Imagining my sister swallowing a load of semen I was about to shoot inside mom sent me over the edge. I leaned back slightly, plowing my hips forward to reach as deep inside her pussy as possible. By the way mom's head tossed around uncontrollably, flicking her hair like a whip, and how her body shuddered, Alice had got back onto sucking mom's clitoris and my cock was doing its job.
Mom screamed loudly on the cusp of her climax and pushed back hard, grinding her tight slit into my pubic bone. Her body shook like a washing machine on its spin cycle as my cock jerked frantically, releasing rope after rope of hot semen inside the reproductive organs that would soon present me with an unprotected, fertile egg.
I fell backwards, completely exhausted having fucked both mom and sister. With nothing plugging her pussy hole, Claire ascended to her throne atop Alice's mouth, sitting straight up, pushing her knees wider apart.
"Eat my pussy and clean your brother's cum out."
"Yes, mom."
"Good girl."
I lay comfortably on the floor, inches away in absolute awe at the sight of mom squirting her unicorn pee mixed with fresh semen into my sister's mouth.
The amazing sight of my fiancee's pussy entrance, involuntarily clenching tight, then releasing quickly over and over like a hydraulic seal being activated to grip, then let go, will stay with me forever.
"That was the most perfect sight I've ever seen."
"For me too, son. Thank you, Alice."
Alice sucked on a mouthful of mom's swollen, well fucked labia and was swallowing too hard for a conversation. I sauntered over to our kitchen while the pair got acquainted properly, poured a glass of water and handed it to mom while she let my sister finish cleaning her.
"Are you dominating her too, mom?"
"I'd like to baby. She's a switch between sub and dom, but I think taming Alice might be fun. Right now, she can't get her tongue far enough inside my pussy to satisfy herself."
"Is she doing a good job?"
"Fucking great. I can see how she could teach you so well."
I stepped back and watched from a distance, noting when Alice kept pulling our mom's ass back down onto her face every time she tried to stand up.
"You have to let go now of me now, Alice."
"I don't want to, mom. Your pussy tastes so good."
"That's your brother's... sorry, Simon's seed inside me too, though."
"I know. I love you guys so much."
Mom stared at me with a question writ large on her face, and I knew instantly why. I smiled back and nodded my head.
"Simon says you can sleep with us tonight, sweetie. Would you like that?"
"Only for tonight?"
"Let's discuss that in bed."
In bed, French kissing my sister and having mom massage and plant soft, encouraging kisses on my neck while spooning me from behind felt wonderful. It wasn't weird at all as we shared each other lovingly.
Alice cleaned all residual semen and the pussy juices mom had creamed on my shaft, explaining that she enjoyed the flavour of male and female ejaculate more than any other.
While cuddling like three spoons in bed with a movie playing on my laptop we talked.
"When did you teach your brother how to lick a pussy, sweetie?"
"A few days after you sucked Simon's cock on his birthday."
"How did you know about that?"
"I watched you doing it. I was passing Simon's bedroom on my way to the bathroom and saw you in there. You were about to draw the duvet across his naked body, then stopped and knelt down. The rest you know."
"How long were you watching me for?"
"Until you wiped Simon's cum from your lips."
"That was more than twenty minutes."
"Yes."
"What were you doing while I sucked your brother's cock?"
Alice turned slightly to look past me to mom since I was middle spoon. She wore another signature sassy grin.
"What would you have done, mom?"
"Hmm, okay. I have another question, baby?"
