"Good morning, Mrs. Erickson." you address your friend's mother.
"Good morning. Have you come to hang out with Esther? She should be in her room." the woman replies.
"Yea, the Dragonblade 4 came out today, and we agreed to beat it together."
"That's... very interesting." the woman responds, clearly having no idea what you are talking about "I am going shopping now, if you two get hungry there is lasagna in the fridge. Just warm it up in the microwave."
"Okay. Thank you, Mrs. Erickson."
You walk up the stairs and open the door.
On the TV screen is a menu of some game, and Tess is sitting on the floor with the controller, leaning with her back against the bed.
Engrossed by the game, she doesn't seem to notice you entering the room.
"What are you playing?" you ask as you walk up to her.
"Uaa~!" she jumps up and stares at you with her eyes wide and her face flushed.
"Haha, gave you a scare?" you joke but then notice that for some reason she has the controller sandwiched between her thighs and against her crotch "Emmm...."
"Ah, shit!" she throws the controller aside and starts stuttering "I... it's just... shit!" frustrated, she covers her face in shame.
You look at the screen again - it shows the settings menu with "Feedback: Vibration Strength" highlighted.
Was she using the controller as a vibrator? Didn't expect Tess to do something like that, but guess girls can get horny too.
"At least lock the door when you do something like this, haha. That's a pro-tip." you sit down beside her, trying to sound cool and dispel the awkward air.
Tess does not seem to respond and just sits with her face buried in her palms, ashamed to look back at you.
"Come on, let's play something." you reach for the controller, at which point she screams "No!" and tries to stop you, but it is too late. As you grab the device, you realize why - one of the grips is covered in something wet.
"Aaaaah, why is this happening to me! This is so fucking embarrassing! I want to die!" she cries out as you stare at your hand slick with her love juices.
"Like... it's not a big deal. Everyone does it." you say.
"But only I get caught in the middle of it by my best friend! Now you think I am disgusting!" she grasps at her short-cut brown hair as if trying to pull it out.
"Not really. Hell, I'd even help you if you asked, haha." you try to calm her down.
"Eeh? That's gross..." she stares at you.
"Oh, sorry, that came out wrong... I meant as a friend..." you realized what you just said and now feel your own face getting hot.
You and Tess spend a few seconds staring at each other in silence.
"Sorry, I probably should just leave." the tension gets to you, so you stand up and step toward the door.
"Wait!" Tess leaps across the floor and grabs you by the ankle "I didn't mean it. I was just surprised, that's all."
She looks so cute splayed across the floor with her yellow shirt rolled up, her tanned back contrasting with white panties that cover her plump buttocks.
"We can do it, just don't leave."
Your heart skips a beat as you hear her words.
"R-really? Are you sure?" you swallow your spit.
"You are the one who offered. Don't back out now."
"Okay..." you turn the knob, locking the door to the room closed.
After this, you sit down on the floor and beckon to Tess, who sits down in front of you, her back leaning onto your chest.
"So, how did you do that?" you say, wrapping your hand around her toned waist.
"Did what?" she asks, confused.
"Made the controller vibrate."
"Huh? When you said 'help' I thought you are gonna..." Tess says, but then stops in the middle of the sentence.
"Gonna what?"
"Never mind." she says in a bit of a disappointed tone, "If you keep pressing the thumbstick to the right while on maximum it will keep vibrating."
It seems when you change the feedback strength it vibrates to indicate the current level, and on maximum it will keep rumbling as long as you hold it to the right.
Doing just that, you press the vibrating controller to the inside of her thigh and drag it along her smooth skin.
"Uuuuh..." Tess makes a funny sound as she inhales.
"You're cute."
"Shut up, you pervert." she says defiantly.
"Hey, I am just helping you, you know."
"Yea, sure. Then what is it poking at my back?" she bumps your hardon with her butt "Guess I'll have to take care of that afterwards."
"You will?" you sound a bit desperate.
"Can't leave you like that, can I?" she turns her head away, embarrassed.
Her words excite you even more and you press the rumbling controller to her crotch, making her quiver in your arms and rub her thighs together.
Tess tries to curl up, but you hold her firmly, feeling her muscles contract as she twists her body, overcome by pleasure.
"Ngggggg!" she clenches her teeth and grasps at the bedsheet hanging from her bed, pulling it off.
"How was it? Not too strong?" you take the controller away for a second.
"Why did you stop?" Tess complains with a delirious expression, a bit of saliva drooling from the corner of her mouth.
"Okay, I won't stop anymore. Hang on there." you say, firmly pressing the controller into her crotch again.
