Jim complied. He grinned at Alyson as she returned it with one of her own. He slowly began moving a hand over his cock as he watched his sister and mother.
Ellen had returned to pushing her tongue up Alyson's cunt. After a few moments she pulled Alyson further forward on the counter, rotating her ups up and placing Alyson's legs on her shoulder. She now had access to the area behind Alyson's cunt. Ellen started licking the thin strip of flesh between her cunt and asshole. After a few moments she pushed her tongue into Alyson's pink rosebud. Alyson automatically clenched her asshole as the tongue began moving into it, but then willed herself to loosen up so the tongue could intrude into it. Ellen began flicking her tongue just inside the entrance.
After a bit she began reversing herself, taking her tongue out of Alyson's ass, across the strip, slowly up the cunt slip… slowly… slowly… driving Alyson crazy with anticipation. Finally… finally - as Alyson cried out - Ellen caught Alyson's clit between her lips and started to gently nibble it. Alyson arched her back a bit to press it into Ellen's mouth. At the same time her hand went to the back of her mother's head mashing it into her clit, essentially cutting off her breathing.
Ellen pulled herself free saying, "Greedy little girl. If you don't behave, mama spank."
Alyson looked at her challengingly, noting the glistening spittle and oils on Ellen's lower face, saying "You wouldn't dare."
Before Alyson could say another word, Ellen had grabbed her legs and twisted her over so she was face down on the counter, her ass exposed to the world. With one arm wrapped around Alyson's legs, Ellen delivered 3 quick, stinging blows to her buttocks. Then, just as quickly, Ellen flipped Alyson back over into her original position.
Both heard Jim's laughter. Alyson shot him a look and said, "Your ass is mine…" as her mother began licking her way down the inside of Alyson's left leg "…later."
Again, Ellen captured Alyson's clit and began working it - at her own pace.
She licked it for a while, then nibbled it with her lips, then with her teeth. Every time Alyson felt she was just about to cum, her mother changed the cycle. It was driving her nuts. Finally… finally, she knew that this time she was going to do it. She began chanting…
"God… god… yes… yes… this time… this time."
She glanced over at her brother who was beginning to pound his meat more furiously as he tried to time his cumming to hers.
"Oh god… mommy… I'm cumming… I'm cumming… MOMMIEEE… CUMMING!!!"
Her body spasmed… and spasmed… and spasmed as it heaved at the jolts of release shooting through it. Slowly she relaxed onto the counter top, her mother flicking her tongue across Alyson's clit just enough to wring post orgasm gasps from her with every contact.
Finally, Alyson just laid there, a smile on her face as her mother's face rose from between her legs. She kissed Alyson's thighs then crawled on top of her to give her a very moist, very flavorful kiss. They broke the kiss and quickly and repeatedly kissed each other on the lips until they turned their heads to rest their cheeks on each other. Both were now looking at Jim.
His cum was everywhere on his torso… his cock, his thighs, his belly, his chest. Ellen looked into Alyson's eyes, gave her a quick kiss and rolled off her body and the counter to stand on the floor. She walked over to where Jim sat, hand still on his cock, milking the last dregs out of his balls - his eyes tightly closed.
Ellen leaned over him and began licking the cum off his chest - causing his eyes to fly open in surprise. Slowly, she licked he way down his body… his chest… his belly… his thighs… and then up to his cock, where a large pool of cum nested on his hand, still wrapped around his cock. She slurped that off as well, swishing it for a second in mouth before swallowing it. She then proceeded to lick both his hand and cock as clean as she could - eliciting a gasp each time her tongue hit his sensitive cock head.
Finally, Ellen straightened up and taking a look at her daughter - supporting herself on her elbows as she watched her mother clean up her brother, and then her son - who still sat in the chair with a shit eating grin on his face, and asked "Jesus, after this, what's a person got to do for breakfast around here?"
