Stiles was sitting behind the counter watching the few customers that were in the store, Erica, owner of 'Erica's Sexcapades' was sitting beside him "Do something useful Stiles, go and make me a coffee" Stiles sighed and got up from his seat just as two customers walked over "I'll serve this customer first" Stiles said smiling at Derek, Erica rolled her eyes and turned to the other customer.
"Did you find everything you were looking for sir?" Stiles asked the customer, Derek looked at the box in his hand which contained a vibrator "Yes, I think so" he replied looking slightly embarrassed "Can I ask you a few questions that may help with your purchase?" Stiles asked, Derek looked at him a little unsure "Okay"
"Is the vibrator going to be used on a man or woman?" Stiles asked him, Derek looks at Stiles answering quietly "umm, a man" Stiles takes the box off him and puts it on the counter "This is the wrong one, it's designed for a woman. Is the person it's for, going to use it on themselves or someone else?" Stiles asked with a little smile. Derek looked away going a little red "They're going to use it on themselves" Stiles nods "And is this the first time they've used a vibrator?" Derek sighs before replying "Yes it's the first time" Stiles comes out from behind the counter "If you follow me, I'll show you what we have in stock" before walking down one of the isles, Derek following behind.
Stiles stops in front of a row of vibrators, all different sizes, colours and textures picking a few up and turning to Derek and holding up the first box "This is small and narrow, ideal for beginners, the next one is a bit bigger and has more girth and the last one is for the more...adventurous person and as I'm assuming it's for you I'd go with the smallest" Derek looks at the boxes taking the box with the largest vibrator from Stiles "Dude are you serious? You can't use that on your first go" Derek rolls his eyes "I want this one and don't call me dude" Stiles puts the others back "If that's what you want, do you want some tips on good technique?" Derek looks at him and nods, Stiles smirks at Derek "It'll be better if we go in the back, more privacy. Erica I'm helping this customer with a purchase" grabbing Derek's hand going through to the back. Erica looks up as Stiles is going through the door "Don't make a mess Stilinski!!"
Stiles takes the vibrator out of the box putting the batteries in looking at Derek "Okay, show me what you got" Derek looks back at him "What?" Stiles smirks at him "Strip off and show me your technique" Derek srips off from the waist down taking the vibrator from Stiles, Stiles looks him up and down "Wow, that's impressive!" Derek blushes a little pushing the vibrator into his ass, Stiles watches him "Be careful with that one, it's really powerful" Derek rolled his eyes and turns the vibrator on moaning loudly "I did warn you" Stiles said with a smirk, Derek looks at him "Shut up!" Stiles looks at him raising an eyebrow "Make me!" Derek walks over to him and opens Stiles jeans pulling them down running his hand down Stiles back feeling something in his ass "You're wearing a butt plug?" Stiles smirks "It's good for easy access" Derek looks at him "Do you fuck all your customers?" Stiles replies with a wink "Only the good looking one's"
Derek turns the vibrator off pulling it out and putting it on the table "Turn around" Stiles turns around bending over, Derek pulls the butt plug out and puts it on the table next to the vibrator putting his hands on Stiles' ass spreading his cheeks pushing his dick in slowly moaning quietly "God, even with the plug you're still tight" Stiles groans as Derek pushes in "That's because you're so big! Now move your ass!" Derek runs his hand down Stiles back pushing him down slightly and bottoms out. Stiles squeezes his ass around Derek's dick to encourage him to move, Derek moves his hips setting a steady pace, Stiles grunts spreading his legs wider "Fuck!" Derek grins as he flicks his hips harshly, pleasure running through his body. Stiles moans rocking his hips with Derek, his dick slapping against his stomach "Harder" Derek smirks "I will give it to you hard" thrusting in harder and deeper, Stiles throws his head back moaning loudly, his dick leaking over his stomach. Derek thrusts in and out, over and over wrapping his hand around Stiles dick. Stiles whines bucking into Derek's hand and down onto his dick the sensation overwhelming him, getting close to his orgasm "Fuck! Don't stop, I'm gonna cum!" Derek fucks him harder "Not going to stop" It's not long before Stiles cums over Derek's hand crying out in pleasure, clenching his ass around Derek's dick, Derek feels him clench moaning loudly getting close to his orgasm. "Fill me up, want your cum" Stiles cries out, "I'm there" Derek calls out as he steadys his hips and fills him, Stiles moans feeling him tense, knowing he's reached his orgasm "Fuck that was amazing" Derek smirks "I'm glad you thought so" Derek picks up the butt plug, pulling his dick out and pushes the plug back in Stiles ass "That will keep you ready for the next customer" Stiles moans quietly standing up and picking his boxers and jeans up putting them on, he turns around as Derek is doing his jeans up and winks.
They walk back out to the front of the store Stiles going behind the counter smiling at Erica "Stiles next time you want to fuck your husband do it somewhere else!" Stiles laughs "Sorry Catwoman" Erica rolls her eyes "Derek, Boyd better not be home late from work again tonight and you owe me 50 bucks for the vibrator!" Derek kisses Erica on the cheek "Don't worry he won't be, Stiles you heard the lady, pay her $50" winking as he walks out of the door. Stiles takes his wallet out giving Erica $50 "Now go to work Stiles before you get the sack" Stiles scoffs "I'm the Sheriff's son, who's going to sack me?" Erica turns to him and laughs "The Sheriff?!"
