Summary
     In which Teddy uses his shapeshifter skills in the bedroom and Billy
     is a size queen.
It's a bit awkward living with your boyfriend when he still lives with his
parents. And his two younger brothers. And his sort-of-maybe-spirit-twin
brother. Not because any of them aren't accepting or understanding of Teddy and
his relationship with Billy—although Tommy likes to give them enough shit about
it whenever he can, but Tommy's a dick who picks on everyone and Teddy's good
at ignoring him. And not because it's hard adjusting to a household with more
than just two people in it like he grew up with. Even though he's always been
good at adapting, Mister and Misses Kaplan have gone above and beyond anything
Teddy could ask for to make him feel welcome and like a part of the family.
Living with Billy is actually pretty awesome in the grand scheme of things.
But it's still awkward.
Mostly because Teddy is a teenage boy with a teenage boy's sex drive who is
constantly in close proximity with his teenage boyfriend with absolutely no
chance of burning off a significant amount of his pent-up, teenage sex needs
because at least one member of his teenage boyfriend's family is always going
to be present in the house at any given time, and any time not spent at home is
otherwise spent superheroing or doing schoolwork or going on dates in public
with friends where stripping your boyfriend and mounting him in desperation is
not exactly going to go over well.
Teddy loves Billy, and he's grateful to have the chance to live with him after
losing his own home. But while he may be a patient dude, even he has his
limits, and he's pretty sure his balls are not only blue but close to dropping
off completely out of sheer frustration.
                                       *
Technically, Teddy's room is supposed to be the guest room at the top of the
stairs that he shares with Tommy, but he ends up in Billy's room every night
anyway (and if Billy's parents notice Teddy coming out of his room in the
mornings, neither of them mention it). But the walls in the Kaplan home are
thin, and Billy's room is right next to the brothers' and across the hall from
the parents', so even though Teddy gets to spend every night curled up in bed
with Billy, it can't go much further than the occasional handjob under the
covers because Billy is a screamer—normally something Teddy finds very
pleasant, but finds frustrating because of their circumstances—and Teddy's
weight makes the bed start creaking loudly if he moves too much.
However, one night, Billy finally comes up with a solution to their cock-
blocking problem.
Still high on adrenaline after helping Spiderman fight Venom across most of
Manhattan for most of the evening, Billy grabs Teddy by the collar as soon as
they slip into his room and attacks his mouth with kisses, one of his legs
wrapping around Teddy's waist and pulling them flush together. Teddy responds
instantly, one hand going for Billy's hair and the other grabbing him by the
ass, squeezing and rubbing and roaming and—
Teddy pulls away from Billy's mouth and gasps out, "Shit, Billy, we need to
stop."
"What? No. Why?" Billy asks, whines, rolling his hips and rubbing his cock
against Teddy's through their costumes, making Teddy groan and hiss.
"We can't, t-they'll hear us," Teddy hisses, trying his best to resist the
overwhelming urge to slam Billy against the nearest piece of furniture and rip
whatever material is in the way of him fucking Billy senseless. He's not
resisting very well, and he doesn't think he can hold out much longer. He
briefly imagines Billy's parents kicking him out in the morning after the two
of them keep the entire building awake with his groans and Billy's shouting,
and decides easily that he won't regret it at all.
But Billy is shaking his head and pulling his hands away from Teddy's neck to
turn blue and light up the room before it fades away again. "Teddy, listen, I
thought of—I have no idea why it took so damn long, but—listen, listen, I
figured something out: a quieting spell cast on the whole room. Now no one can
hear us, okay? So please, please don't stop, I need—"
That's about as far as he gets before Teddy lifts him up and tosses him on the
bed, making it squeak loudly in protest. Teddy follows after him, climbing on
top of him and kissing him hard enough to bruise. All of his teenage boy lust
is exploding out of him all at once, and he should feel guilty as he rips
Billy's costume apart, but he really doesn't care, and Billy can always magic
himself some new spandex, anyway. He doesn't stop to think about it as he zips
his own costume open and pulls his cock out, leaning down and pressing it into
Billy's bare hip, groaning at the delicious feeling of skin on skin.
"Billy— Bee, I need the— I dunno where—" Teddy grunts ineffectively, but Billy
understands and his hand lights up a bright blue again.
"Don't need it, 's fine, please, Teddy, hurry," Billy groans when the light
fades, and sure enough, when Teddy slips a finger inside Billy's hole, he finds
it already lubed up and stretched.
Teddy has to pause for a short moment to appreciate the fact that dating a guy
with magic powers is fucking awesome.
But the moment doesn't last long, and Teddy's already sliding his finger back
out, rolling Billy over onto his belly, pressing his face into the pillows and
pulling his ass upwards. Normally, the two enjoy a bit of foreplay before
getting this far, but they're desperate after months without much action and
too busy riding the waves of adrenaline still pumping through them to be able
to slow down. Teddy lines himself up and thrusts forward, filling Billy up to
the hilt. Billy squirms and moans loudly beneath him, hands gripping hard into
the sheets at the sensation of being filled, while Teddy breathes heavily above
him, hands squeezing around Billy's hips hard enough to leave bruises.
Teddy knows he should wait for Billy to adjust, but he can't hold still now
that he's finally, finally inside him after god knows how long. He slips out to
the tip before slamming back in, making Billy whimper and the entire bed groan
underneath them. He does it again, this time faster, and again and again, until
his pace is so fast the bed starts to sound like it's about to break in half
any moment beneath their knees, but it's Billy's rhythmic shouts that really
fill up the room with noise. Teddy can barely hear the sound of skin slapping
against skin under all of Billy's throaty moans and howls, but he likes the
chorus of cries that come out of him, calling out, "Teddy—nngh—more, gimme
more," and "holyshitohmyfucktherethereTHEREOH," every other second.
But apparently Billy doesn't just want more thrusts aimed at one spot. Soon,
he's reaching an arm back and squeezing Teddy's wrist, trying to get his
attention. "Teddy, more, I want—" Billy groans, and Teddy leans forward over
him, keeping his hands in place and his thrusts never slowing down, and bites
gently at Billy's shoulder.
"Tell me what you want," Teddy grunts and Billy's fingers squeeze into his
skin.
"Bigger, I need you bigger," Billy gasps and Teddy takes a second to understand
what he means before he doesand—
Oh. Oh.Yeah, he can do bigger.
Teddy doesn't stop moving inside him as he leans back up, but he concentrates
and feels Billy's walls closing down around him as his cock grows wider and
stretches just a bit longer. Billy shouts and squirms, crying out louder and
louder the more Teddy thrusts into him with his adjusted size. But his hand
still hasn't let go of Teddy's wrist and he squeezes again what can't be more
than a minute later.
"Bigger," Billy moans, and Teddy blinks in surprise, but he obeys, because hey,
Billy wants it and it feels damn nice squeezing a bigger cock into Billy's
tight, wet hole. He doesn't make himself much longer, because there's only so
much room before he can't push in up to the hilt, and he doesn't want to lose
that sensation, but he makes himself quite a bit thicker this time, grinning
wildly when Billy jerks and comes underneath him without a hand touching his
dick. Teddy doesn't slow down, still fucking him fast and hard, even though
Billy's quite obviously spent despite the constant groans he makes with Teddy's
every movement.
But then Billy's squeezing at his wrist again, what can't be more than two
minutes later, and while Teddy can't lift a hand away from Billy's hips to
reach beneath him and check, he's pretty sure Billy's already hard again.
"Bigger, bigger, bigger. Please, Ted, I want more," Billy hisses underneath
him, and Teddy finally feels a bit of hesitation.
"Don't wanna hurt you," he pants, but Billy shakes his head against his pillow.
"You won't, I pro—nnghAHH—mise," Billy cries out, "So please?"
Teddy grunts and does as he's asked, surprised when there's little resistance
inside Billy to his growing size, and he figures it's just more magic at work.
But he's made himself so big now that keeping his fast pace is suddenly awkward
and difficult, so he starts to slow down, dragging out low, stuttering groans
out of Billy and shakier, dangerous creaks out of the bed. Apparently this new
size and slow rhythm is exactly what Billy wants, because he starts going
wildunderneath Teddy, hands groping around at anything and everything, his back
bowing with every thrust, and his legs shaking and jerking each time Teddy
slides out and slams back in, the loud noises coming out of him going from
obscene to ridiculous.
Normally, Teddy could make this last for hours if he really wanted—working slow
orgasms out of Billy is one of his favorite things to do, after all—but that's
not something he can do right now. He needs to come, and he needs it soon.
"Bee, I wanna—" he starts, but Billy isn't listening and talking is difficult
anyway, so he just squeezes Billy's waist in warning before lifting him up,
turning him around and dropping him back on the bed without pulling out of him
for a second, the bounce when Billy lands driving Teddy somehow deeper and
making Billy groan and Teddy grunt. He leans forward, grabbing Billy's thighs
and spreading them open wide as he leans forward, pressing open-mouthed kisses
to his neck and his shoulders. Billy's hands stop waving around to wrap around
Teddy's shoulders and dig into the skin there, and if Teddy wasn't a fast
healer, he's pretty sure the nail marks Billy's leaving would last for weeks.
Billy doesn't have to ask this time as Teddy makes his cock stretch and grow,
until he finally starts to feel Billy's walls resisting to expanding any
further. Teddy marvels at the feeling of filling Billy up so completely, and
Billy moans appreciatively beneath him. His rhythm starts to grow frantic again
as he slams into Billy again and again, and he bites into Billy's skin. "'m
gonna come," he grunts, muffled around Billy's shoulder, and Billy nods above
him, fingers squeezing into his back.
It only takes a few more thrusts, each one more careless and rough than the
last, until Billy's heat and tightness is too much and Teddy comes hard,
gasping and panting as his hips jerk forward again and again, pumping out his
load. The sensation is enough to send Billy over the edge again, too, as Teddy
rocks his hips forward, riding the waves of his orgasm, and Billy shouts above
him, nails scraping hard against Teddy's skin and a growing wetness spread
between their bellies.
Teddy slowly lets Billy's thighs go, sliding his arms up and underneath Billy's
back to pull him closer, and Billy uses his free legs to wrap around Teddy's
waist and keep him from sliding out.
They lay there together, sticky and sweaty and very, very spent for a long
while, Billy running a hand lazily through Teddy's hair while Teddy kisses
along his neck.
Eventually, Teddy regains the ability to speak and mumbles, "So, that was
awesome."
"Mmm," Billy hums.
"And uh. I kinda want to do it again."
"Mmm."
"Like, maybe in a minute or two."
Teddy props his chin against Billy's chest to look up, finding Billy staring
back at him with a growing smile.
"You perv," Billy teases, and Teddy smirks, rolling his hips forward once, very
slowly, and enjoying the loud, keening noise Billy immediately makes. Teddy's
cock jerks and starts to harden, already eager for round two, and Billy
shudders around him.
"Who's a perv?" Teddy asks while Billy's legs squeeze around his ass in an
attempt to pull him deeper.
"God, I don't care, me, me, I'm the perv, fine, whatever, just fuck me again,
quick, please."
Teddy grins and rolls his hips again obediently, licking along Billy's jaw
until he finds his mouth and kisses him, content and lazy.
