Mary and Taylor cum, and you're hard again already.

You cup Mary's buttocks in your hands and squeeze, finding them firm and muscular from all the walking of her waitress job.

"Deeper, hon," Mary says.

You adjust your knees and press forward from behind Mary as she crouches on all fours on her bed, facing the mirrored closet door.

"Oh!" Mary calls out.

"I can't wait to know what that feels like," Taylor says.

"Good, honey," Mary says. "Tom feels good."

Mary's pussy is hot around your cock and very wet. You hear little squishes as you press into her. Looking down, it's just as Mary said, what made her uncomfortable about rear entry. Her 'poop-hole', as Taylor called it, is right on display. A proud, dusky-reddish star, nothing wrong at all.

"You too, M... Mrs. Forbes," you say. "You feel good."

"Give me a good one, Tom, hon," she says.

"You bet."

You give your best to Mary Forbes, thrusting into her from behind. Her heavy breasts swing under her chest, an extra gift of the mirrored sliding doors. Her dark brown hair, still loose like you never see when she's working, tosses with your motions together. The bed squeaks with each hard thrust you give her. You see Mary's reflected face go by stages from happy and eager toward flushed and aroused, and finally intent and focused as she fucks back at you, digging with her hips for a climax.

From time to time you hear a sigh or an "ooh!" from the side, reminding you that your sister Taylor is there, waiting and hoping for her own turn with you.

"AH! AH! Tom! YES!" Mary cries out. Her head bucks up, then down. Her body tenses, highlighting the developed muscles around her shoulders. Her pussy squeezes down on you. HARD.

"Ow, oh, wow!" you cry out. "Whoa!"

"AH!" Mary cries out, relaxing for a moment, then squeezing down hard on your cock. "JESUS!"

It's too much, and you join her in paradise. Your cock swells inside her hot, tight wetness and you let go, answering her cries of joy with your own. The bed shakes as your bodies strain against each other at the height of pleasure, and your eyes blur and close.

When your come down from the peak of joy and your vision fades back in, you carefully withdraw from Mary, stash your rubber in a handful of tissues, and collapse down beside her flat on your back, your head to the foot of the bed.

Mary looks down at you, her head propped on her elbows, and grins. "Was it good for you too, hon?" she asks.

"Good. Yeah. Really good," is about all you can manage. Waves of warm, tingling pleasure wash over your body. Your cock softens as you lie back, relaxing.

From the other side, Taylor strokes her fingertips down your body. At first you shiver with the ticklish feeling, but it turns into another wave of warm pleasure.

"Got anything left for me, Tom?" she says. "Please?" She makes big pleading eyes at you.

You feel a twitch, a pulse, and your cock swells toward full again.

"Mrs. Forbes, can I have another rubber?" you ask.

"Use one of mine," Taylor says.

Mary takes it from Taylor and tears open the package. This time, with a little experience, she has an easier time of unrolling it over your big cock head and down your thick shaft. Your sister's favorite brand is smoother and thinner than Mary's, and slick with oily silicone lube.

"Going first-class, girl," Mary says. "Your sister knows her stuff, Tom."

"We're really gonna do it, Tom, really!" Taylor says.

God she's pretty, her lush curves all naked for you. And that big smile. You've stared at her plenty, even got a few peeks at her pussy before today. But now that you've tasted each other. it's time for...

"Mmph!" you say. Taylor pounces on you with a kiss tasting of Mary's rich cunt juice that quickly turns into a tongue battle. You wrestle Taylor around below you and part her legs.

"Turn round, sillies, the pillow's on the other end," Mary says.

You and Taylor break up in giggles but do as she says. Taylor lies back. Her blonde hair fans out across the pillow and her boobs slump toward her sides.

Mary shifts off the bed and kneels beside it, putting her elbows on the bed, folding her hands together and bowing her head. You catch a few words. "our Lord ... your loving children Thomas and Taylor Jackson ... may they ... each other ..."

She's praying for you. You glance at the embroidered motto over Mary's headboard. This is my command: Love one another. -- John 15:17. For Mary, God is love, and no foolin'.

Taylor laughs. "Look at ME, silly."

You have no problem with that.

Taylor reaches down. "Do me, Tom," she says. "Do me like those girls who keep calling, asking for you."

"I'll do you. I'll do you better," you say.

"OH TOM!" Taylor cries as you enter her.

"...Amen," Mary concludes. "Now you do her good, hon."

You lie with your sister in Mary's marriage bed, slowly thrusting in and out as you watch Taylor's face. With every sigh, whimper, or motion of her under you, you adjust your strokes, learning how her pussy wants to feel you. Taylor's face and neck get pinker and her breath gets faster and deeper.

You feel her body tense under you, gathering for a climax that bursts out of her. Taylor whines. Her head rolls up off the pillow, then falls down. Her pussy squeezes on your shaft. She has five spasms of orgasm before lying back, limp. But as you keep thrusting, she regains herself and looks into your eyes.

"Oooohhh Goddd Tommm," Taylor says. "Yessss, keep doing it."

You hold out through another climax and another collapse. But when Taylor loses it on your cock for the third time, you can't help going with her.

You wake up in Mary's bed with your naked sister cuddled close. There's a shower running in the next room. Your cock still throbs, two hot fucks still not enough to keep you down long.

"I love you, Tom," Taylor whispers.

"I know," you say.

"Bastard, you're supposed to say you love me too!" Taylor says, whapping you with a pillow.

"That's what I meant!" you protest.

"Say it."

"I love you too, Taylor," you say. And you do. And Mom. And your sister Madison. And your college girlfriends. Well, mostly. And even Mary Forbes.

The shower stops, and soon Mary enters, her wet dark hair pulled back severely in a bun behind her head, but still naked.

"Upsie daisy, lovebirds, we need to get Taylor and me to work," Mary says.
