Mom stopped sucking and started blowing cool air over his dick, and after a few moments, Tim was back down again. Tim realized this was edging and Mom did it beautifully, kept him high on endorphins but not to the point where he was shooting his load. He hadn't said a word, except moans and groans of receiving great pleasure. Tim felt himself coming down from an impending shoot, and he heard Mom say, "Come on, time to fuck me. I want that dick inside me." Tim understood then who wore the pants in the family when it came to sex. Mom was calling the shots, when, where, how and with whom. Funny, Tim thought, he always thought of Mom being somewhat submissive, but then he did read once that some women are dominant vertically but submissive horizontally, so maybe it can work the other way too.
Mom stood and pulled Tim toward her, kissing him. Tim felt his cock pressing into her lower belly and her fine pubic hair tickling his balls. "Doggy," she said, "First!" She turned around and leaned forward, spreading her legs laying her hands on the coffee table. This gave Tim his first view of Mom's naked ass and exposed pussy. The skin around her pussy was a little darker than Emma's, her trimmed pubic hair invisible from this angle.
Tim couldn't help himself, he got on his knees behind Mom and rammed his tongue into the puffy cavern, licking all the way up from her clit to her asshole, then back again. He hadn't gone anywhere near Emma's asshole but he just had to do it to Mom, he wasn't asked, he just did it. She tasted different to Emily, not a lot different, but still different. He tongue fucked her, using his bottom lip to wipe across Mom's clit when his tongue was otherwise busy. He kept this up for a while and as he felt Mom getting more excited, closer to an orgasm, he lifted off her and he quickly stood, grabbed his dick and just rammed it inside her.
Mom gasped as his tongue left her pussy but squealed as she felt Tim's cock sliding inside her. He wasn't gentle and his actions slammed his hips into her ass, nearly pushing her off balance. Tim didn't seem to care at all, he was fucking her, strong and hard, his prong a piston delving deeply into her. Mom gasped and moaned as her plugged her hole, filling her, she was loving it, Tim knew, what a slut! His own mother! Mom pushed her ass back as he drove into her, and it wasn't long before she started to twitch, signaling an approaching orgasm, she moaned, then clenched her muscles as Tim just pulled her back and pushed her forward onto his dick.
"Yes-yes-YES-YES," Mom called as an wave of pleasure washed over her, sweeping out from the depths of her pussy. Tim's cock pounded her pussy, unlike anyone who had fucked her before. He just seemed to know exactly how she liked it, without even asking. 'Fuck, he's good,' Mom thought, and he's only eighteen!
"Wait here a moment," Tim said, as he disengaged, "Be right back." She heard him leave the lounge, but didn't know what he was up to. Didn't matter, she was still high from the endorphins running through her system. Mom fell back onto the lounge suffused with the post-orgasm afterglow. A few moments later, Tim reappeared, his cock still mostly hard, Mom noted, 'He's such a stud,' she thought but didn't pay too much attention to what he was carrying.
"Mom, off the sofa," Tim said, no ordered, Mom thought, what's he up to? "Come on, on your knees, rest your tits on the sofa," Tim again ordered her.
"You gonna fuck my ass?" Mom asked.
"Yes, I am, lots of lube and a condom," Tim replied. Tim had not fucked Emma or Emily in the ass, yet, but he had done one of his buddies from junior high some years before. The guy was a complete fag, and it was a going away gift for him. Tim was surprised at how easy it was to suck and fuck a guy, very different than a girl, but he was curious and they would never meet again, so Tim obliged the guy. Thank fuck no-one else figured it out, but Tim satisfied his curiosity and was rewarded with a much better experience than he had really expected.
Tim gave his dick a couple of tugs, not that it needed it, but he did it just the same. Using his teeth, Tim ripped open the packaging, placed the end over his knob and rolled it down. Tim wiped the lube over Mom's asshole and onto his cock. "It's coming Mom," Tim said as he ran his fingers up and down her ass crack, "Now!" Tim positioned himself on his knees behind Mom and spreading her legs a little further, held his dick, aiming it at her puckered ring. He felt his cock pushing the ring aside and heard Mom saying, "Oooohhh, relax, relax," over and over as his dick spread her sphincter. "Oh, yeah, fuck my ass!" Mom called.
Tim slowly entered Mom, pushing his strong man meat into her, spreading the cheeks of her ass as he did so. He heard mom's gasping, her moans and he was just concentrating on the feel of a band of muscle sliding along the length of his dick. He pushed into her, slapped his hips on her soft ass cheeks, then pulled back, easily, feeling the coronal ridge of his dick touch the inside of Mom's asshole. He pushed in again, a little faster, then pulled back, again trying to pull back only until his knob touched her ring. He deliberately timed his strokes, trying to get a feel for his movement, speeding it up as he became more confident.
He didn't want to cum in the condom, that was for her mouth, Tim thought. Mom moaned as he sped up, "Yeah! Yeah!" She called. Tim noticed Mom had slipped an arm down under her, and knew she was diddling her clit, masturbating while he was poking her ass. He kept it going, but with the condom and the muscles of Mom's anus the only thing really stimulating him, he knew he wasn't going to cum anytime soon. Mom's breathing became a little ragged, then her thighs started shaking, her moans closer and louder, "F-uu--uu-u-uk cumming-cumming-NOW!"
Tim saw the muscles in Mom's ass tighten, then her asshole grabbed his cock, hard, nearly pushing him out. He held her thighs ramming his hips into her, holding on while the puckered hole clenched his cock really hard. He felt a surge in his cock, but it was blocked by the incredibly tight grip Mom had on his dick. 'Fuck!' Tim thought as he realized that it was Mom's ass that stopped him from shooting his load into the condom. He didn't want that. As Mom's orgasm began to fade, he pulled back, timing a little pull out with every spasm and relax movement of the ring that gripped his tool, until he could drop out of her entirely.
He quickly cleaned up his dick, rolling the condom off, using a tissue to hold it. With more tissues, Tim wiped Mom's ass, the mix of lube and ass gravy not a good look, but he did it anyway. Tim dropped the wadded tissues and condom next to the couch, and kissed Mom on the back of her neck.
When he was done, Mom crawled up onto the couch laying out, beckoning Tim to join her as she rolled onto her side. Tim lay on his back, mostly on the couch but not all, he had to put one foot on the floor, just in case. "That was pretty good fucking, Tim!" Mom said as she kissed his cheek. "Three holes and you filled every one of them, now you're going to have to cum in my mouth." Tim was still trying to catch his breath, "Tomorrow, you can cum in my pussy." She paused a moment, "Then watch your father eat it out of me. Would you like that?"
After this, there wasn't much that Tim thought would surprise him, but this did. "Dad? Eating my cum out of your pussy?"
"Yes, he'll love it, believe me," the certainty in Mom's voice was, for Tim, another mini-shock. "He'll love draining your dick any time. Either end, but he would prefer it in the mouth."
Tim wasn't real sure of this was really happening or just a dream now. This was so far out of his perception of what Mom and Dad are like that he was having trouble handling it. He tried to move just a little and nearly fell off the couch.
"No, not working," Mom said, "Come on, sit up and I'll give you a blow job, a real blow job." Tim couldn't sit up fast enough, and in moments, Mom had his cock in her mouth, tonguing his knob, caressing his balls, licking his shaft, then getting to it in a serious way. Tim felt his cock being massaged by her lips, her tongue, movement up and down being wrapped in by the inside of her cheeks. There was a rapid build up, just like there was before, his excitement growing with every stroke of Mom's tongue, every time her lips slid along his shaft, touching his coronal ridge. Mom didn't stop this time, she kept sucking away and Tim willed himself to not enjoy it, to make it last. Within a few minutes, Tim was right on the verge and he was going to shoot, his balls had swollen, his sack had tightened and he was going to shoot! He moaned and groaned "Now!" he cried as his balls jumped, his cock throbbed and a stream of semen flew up his dick and out, into Mom's mouth. The massive shot was accompanied by a wave of intense pleasure that started in his balls, his cock and swept through the rest of him. Again and again he shot then a forth time, each time with that wave of intense pleasure, it didn't seem to diminish at all.
Mom hadn't stopped sucking his dick, her motion not interrupted at all by his shooting but even her expert sucking skills were not enough for his to keep his erection. As he flagged, Mom slowed, then stopped. "Yummy!" Mom said, "That was fucking delicious, tasty as all fuck! Oooh I can't wait to get a taste of your sister now!"
"MOM!" Tim croaked as best he could. Swallowing he said, "Mom, you think you might be being a little bit of a slut here?"
"Yep, and fucking proud of it," she replied, "Can you walk? 'Coz I wanna go and see how your Dad's getting on with those two little beauties." She stood holding her hand out. Tim looked up at those magnificent breasts, the light fur covering her pussy, the gorgeous 'older woman', and he just fucked her, had his dick sucked and cum in her mouth. Who would have thought this was going to happen a couple of hours ago. He loved his Mom, then realized, shit, he did love his Mom, in every sense of the word.
He took Mom's hand and stood. Mom led him to the main bedroom where they could hear a lot of ooohs and aaahs some rhythmic pounding on the bed. Fuck, Tim thought, Dad must have balls of steel if he was still fucking Emily, or Emma. He wasn't prepared for the sight he got as he walked in the room. There was Emily, on her back, legs spread, with Dad's head between her thighs. She was moaning in the delight Dad's tongue was giving her.
Dad was on his knees, eating his daughter and behind him was Emma. Emma had some sort of harness on her and Tim knew that it had to be a strap on. Emma's ass was pumping as she was reaming Dad's asshole. Emma was also lost in pleasure, her movements not as smooth and practiced as those of a guy, but she was fucking Dad well. Mom and Tim took the tableau in, Mom not moving, letting things play out. In a few minutes, Emily started thrusting her hips up at Dad's mouth and her breathing became more ragged, moans louder and her body shook, her thighs clamped Dad's head as she came.
