Chapter 2: As the Betas Grow So Do We.

A/N: Sooooo, this is about to gain another kink. :D

They bust into Derek's loft gripping at each other's faces so hard that their hands are bruising each other. Derek's tongue is slamming through Stiles' lips and is domineering all of the strength from Stiles' body.

Stiles loves Derek like this. He loves it when Derek gets pushy. It happens whenever he has been hot and bothered all day and Derek always hits all the right spots furiously for Stiles as if his sexual energy is a rage that can only be released by making Stiles cum as violently as possible as many times as possible throughout the night.

Derek runs a rough hand up beneath Stiles' shirt making Stiles arch his back trying to get in closer as he gets pushed into the wall. He moans fanatically as Derek's lips find his neck and start sucking bruises that heal only twice as fast as a normal human. There is something about the way that Alpha mates mark each other that allows them to suck bruises and leave marks all over the other's body. It makes the whole experience more genuine, hotter, needier.

*gasp* Stiles elicits as he feels Derek rip open his clothes. "I thought we talked about this" he says momentarily annoyed.

"Your point being?" Derek inquires before going back to Stiles' neck and descending down his torso licking, biting and sucking bruises on every inch of skin he is allotted.

"mmmmhhhpphhh" Stiles moans. "Nothing"

Derek smirks into Stiles' chest as he continues to bite at Stiles' nipples. He knows how sensitive they are. He knows if he wants he can get Stiles off from just this and the stroke of his hands up and down Stiles' back and ass. He wants to get Stiles in a frenzy. He loves it when Stiles goes nuts. It means he can go as rough as possible; that he can ravish Stiles. It means he can engulf himself in the beauty that is his mate and fuck him relentlessly until completion and still go several more rounds until they both actually pass out from the ecstasy.

"What's going on?" Danny says startled from his sleep. The sounds he has heard and smells now punctuating the room fill his brain as a shirtless Isaac wakes up groggily next to him on the sofa.

"Hmmm? What's wrong Dan- mmmm I'll take some of that," Isaac says as he smells the scent of sex in the air.

"ahhh…. Yes please." Danny says as Isaac sucks on the back of his neck and runs his hands down his chest.

The sounds of the two now woken betas only serve to entice the two alphas more.

*Grrrr* Derek grunts out possesviely as he returns to Stiles and the sexual rub down.

"Oh God yes!" Stiles exhales as he loses himself to the moment knowing the thought of group sex shouldn't be this arousing.

Isaac, Danny, Stiles and Derek get louder as the rip off the rest of their partners clothes off and proceed to have sex in the middle of the .

Danny flips around and pushes Isaac over the edge of the couch and bites at his neck and stroking at Isaac's now full erect dick.

"mmmm" Isaac grunts as Danny strokes him just shy of perfectly.

"This is so fucking hot." Stiles mumbles as Derek licks and sucks and rubs him down. His grazes setting off sparks beneath Stiles' eyelids as he shuts them tight in pleasure.

"Yeah." Derek says as both a question and answer. Then he bites down and strokes Stiles crack extremely hard causing him to scream out.

"uuhhhhmmmmmppphhh" Isaac gasps as Danny already starts slamming into him, completely unable to control his lust. "Danny!" he barks as Danny's cock slams into his prostate.

"Derek…" Stiles trembles out as he feels the pressure rising in his lower abdomen.

"This is exactly how I want you Stiles." Derek says redoubling his efforts trying to speed up Stiles' orgasm.

"Ohhhhh…"

"Danny.."

"Isaac, you're so good."

"Der—" Stiles cuts out as he cums for one of many times tonight. Especially, with the moans of the betas egging him on he knows there is no way any of them will just stop and be outdone by one another.

Derek moves straight down to lap up the semen drinking in every flavor of his mate. Then, Derek goes to suck on Stiles, not even allowing him a refractory period.

"God…" Stiles says wincing. "I'm not sure whether to ask for this treatment every time we have sex or to attempt to ban it."

"Shut up. You know you love this more than life itself."

"True." Stiles says his heart spiking faster as his ears fill with Derek, Isaac and Danny's moans and groans.

"Danny…."

"Me too Isaac."

Danny thrusts into Isaac a few more times before Isaac erupts all over his chest, convulsing around Danny and gripping him tighter ripping the orgasm out of his mate as well. Then Danny collapses on top of Isaac heaving in and out long satisfied breaths.

"Oh god Derek let's get going I need more."

Immediately Derek moves his head to Stiles' rim and starts exploring. He licks at the entrance, circles around it, pulls Stiles down into the waves of desire and pulls him into another orgasm from the teen as he licks at his ass and palms his dick.

"Oh fuck yes! Derek. Now. I need it now. Give me more. I want it. Now!" Stiles demands after his second orgasm.

"No problem," Derek growls out before moving his entire body and then lifting Stiles up, flipping him around and slamming him into a wall. "Stiles, you're amazing." He whispers into Stiles' ear before slipping into him.

"Knock it off Derek. You can sweet talk me later tonight when I'm not so desperate for you fiery touch. God! How you set my body ablaze."

"Works for me." Derek says before speeding up. He quickly finds a rhythm. He pulls out long and slow drawing out moans and sighs from Stiles' taught form and then he slams hard into him rapturing himself in the tight heat that makes way for him as he impales Stiles on himself taking everything he wants from the boy's lithe body.

The first round ends with blinding speed as Derek pounds into Stiles making him eventually ejaculate a third time before whiting out and getting knotted and pumped full of Derek's semen awakening to the roar of his lover.

The night settles down after that. Mostly just shower sex, floor sex, and bed sex until the four werewolves pass out completely at around 5 A.M. all full sated for their sexual needs, at least for the next few days.
