An unplanned threesome

Jan clearly doesn't like the idea of sharing you, though she claims otherwise. You can tell that much based on where she's trying to draw the line.

"Alright, April can stay for awhile," she concedes. "I suppose it can't be helped. But she has to cover a third of the rent, and do her share of the chores."

"Like keeping our brother serviced?" April asks.

"That's not a chore," Jan replies.

"You talk about it like it is. What with your 'arrangement' and all."

Jan goes red in the face. "No, that's..."

"Well," you volunteer, "it's a mutual thing, really. I also help her out when she needs it."

"Oh?" April seems interested in this new piece of information. "What's your side of the arrangement?"

"I, umm, I, uh..."

"We agreed that masturbation isn't allowed," Jan supplies, still blushing. "So we take care of each other when needed. Just when needed. There's no schedule or anything, so it's not a chore and there's no need for you to get involved."

"Oh, but if I can't masturbate, someone will have to help me too," says April, affecting wide-eyed innocence. "Are you going to do it, Jan?"

"Ew, no way," she says, shaking her head.

Jan realizes her mistake a moment later. Both sisters look at you, April with a smug grin and Jan with an expression of alarm.

"Oh," says April, as though she hadn't expected this turn of events. "Then I guess it's up to our brother to take care of things."

"No, no," says Jan quickly. "I... just let me think for a minute."

"I'm feeling a sudden need to touch myself," April says, sliding a hand down between her legs. "If someone doesn't help me out, I might squirt on the carpet."

"Stop that!" Jan snaps. "Just, ugh, hang on a second. This is so... so complicated. Alright, fine. But no funny business."

"Can I say something?" you venture.

"No," they say.

April leans back on the couch, shucks her jeans, and reveals she was wearing nothing underneath. "Okay, big bro, time for you to do your part."

Jan rolls her eyes. "Oh, just get it over with already."

With your older sister watching you like a hawk, you put on your best poker face and take your customary cunnilingus position. April is already quite wet and eager, her slit glistening invitingly. You can smell her arousal and see a tiny drop of her fluid hanging from her pink lips.

With two fingers, she spread herself apart. "Come on, stick your tongue in there. I'm ready for it."

"Ugh, seriously, dude?" Jan says in disgust. "I JUST got you off a few minutes ago, and now you're getting hard looking at your little sister?"

"It's not my fault," you mumble.

As you're about to start in on April's pussy, Jan jumps in and unzips your fly, freeing your erection.

"Let's just take care of this quickly," she says.

There's an awkward minute where the three of you figure out your positions, then Jan's lips are wrapped around your cock. Her tongue flicks across the underside, teasing the sensitive spot. April spreads her legs wider and pushes her hips toward you, and you eagerly press your mouth to her wet pussy. You lap up her juices and plunge your tongue deep into her. She shudders and gasps, writhing under your oral ****.

April isn't the only one feeling good. Jan's blowjob is getting the job done quickly. You moan into April's pussy as your orgasm nears. Then, you feel her body tense and her pussy tightens around your tongue. Her whole body trembles and she lets out a long, low moan. Then, suddenly, hot fluid splashes onto your face.

"Fuck, bro, that's good," she groans.

"Holy shit, you squirted," Jan says, her mouth coming off your dick for a second.

"J-jan," you stammer, teetering on the edge, "If you don't finish me off quick, I think I'm going to stick my dick somewhere we'll both regret."

She immediately wraps her lips around your cock and sucks you into the back of her throat. The warm, wet confines of her mouth and her active tongue is all it takes. Your hips jerk as you shoot a load into her mouth.

"Ah, fuck," you sigh, leaning back against the couch.

Jan swallows and then leans back, wiping her lips. "Better?" she asks.

"Yeah," you reply, catching your breath.

April leans forward and licks some of her juices from your face. "I love you, big bro."

"Ugh, you two are gross," says Jan.

You stand up, grinning to yourself as you head to the bathroom. As great as that was, you get the feeling that something even better is right around the corner.
