A few nights later

Of course I agreed to Vi hosting a session at my dorm, I agreed with Vi that I would be there for a bit and then retreat into my room if she starts to feel comfortable and wants to tease him and I a bit more intensely. Luckily I have a fairly big dorm room with four total rooms. Two bedrooms and a main room with a small couch, TV, small dining table and a bathroom.

"Are you sure about this. Erik? I'm going to be pretty openly flirting with him in front of you."

I nod: "I am babe, I'll give you a signal if I get too uncomfortable with it"
I don't think I'll stop her at any point. This burning desire to see her be a slut, a slut for me. Positively overwhelming.

A knock at the door. Showtime.

"I'll answer the door?"

Vi nods and sits down at the table with her laptop open, I open the door and I see Bri and Trev.

Bri is a ditzy looking brunette, her is tied up in a messy bun as she types away on her phone, she looks and seems like a completely average woman. A pair of simple jeans and a zip up hoodie, my eyes cant help but glance down to her chest, it seems that hoodie may be hiding a large set of breasts but otherwise she seems disinterested and annoyed. She looks up at me with a distant and bored expression and nods in greeting.

Trev is an athletic olive skinned, above average height brown haired man. His hair is cut short and simply styled, pushed back behind his ears. He also is kind of... average? I'm not sure what I expected. He's somewhat well built, your average casual gym goer. He looks at me politely and addresses me as he extends his hand; "Hey, Are you Erik? Vi told me to come to this dorm number."

Vi calls from behind me "You're at the right place guys, welcome!!"

I shake his hand and let them in as I stand aside, they sit down at the table and start working and chatting idly as I sit down on the couch and mindlessly scroll through my phone. Vi and I purposefully put the heat up before our guests arrived that way it looked completely natural that Vi was wearing a simple grey sports bra that displayed a generous amount of cleavage and showed off her toned torso, she accompanied the bra with a pair of long grey sweatpants. She also decided to wear a simple black zip up hoodie that she has kept half zipped, just to ease her nervousness and would undo it if she felt comfortable as the night went on.

"Sorry it's so warm guys... maintenance is being done and we only found out right before you both came, sorry." Vi smiles sweetly as she reaches for her zip. "I hope you don't mind." Vi casually undoes the zip, her tits almost burst out as she shrugs the jacket off. Bri is scrolling away on her phone but Trev is practically drooling as he stares at my girlfriends tits. I watch from the corner of my eye as Vi leans forward giving Trev a good look down her sports bra, she whispers into his ear which leads to him clearing his throat and looking over his shoulder at me, I manage to avert my gaze before he realizes I'm watching them. I glance back in time to see Vi biting her lip slightly with a mischievous grin as she looks past Trev to me.
She switches attention back to the group.

"Wow Trev, you're surprisingly smart, I though you were just a gym rat, but you have brains to go with those muscles of yours." Vi leans on her hand and looks at Trev invitingly.
Trev clears his throat as his eyes dart in my direction, "Haha yeah thanks."

"How often do you go to the gym? Often right?" Vi punctuates her question by reaching up and caressing his arm.

Bri looks up curiously and also sneaks a glance at me, I continue to scroll through Twitter, not reading a word on the phone as I try and watch the group subtlety.

"Uh, I try and go a at least 3 times a week, how often do you go?"

Vi giggles as she leans back and props her chest forward as she raises an arm and flexes her arm, "I don't, is my figure that impressive that you thought I did?"

Bri's brow furrows as she looks at Vi and Trev and then towards me. She rolls her eyes and grabs her bag and announces: "It's too hot in here, I got practice to get to, are we done for the night?"

Before Vi can answer Trev shakes his head and says, "We can do a bit more without you that's fine, but you'll owe us."

Bri shrugs and grabs her laptop and bag, she eyes me judgmentally before leaving the dorm room. As I look back at the table I make eye contact with Vi. She pushes a strand of hair behind her ear and raises her eyebrows and looks toward the door.

The signal.

I exaggerate a yawn and turn to Vi and Trev, "Hey dudes, I've got my own work to do." I stand up. "If you need me I'll be in that bedroom there. Vi, you know where everything is obviously so help yourselves." I smile and walk into my bedroom, I don't fully close the door and leave it somewhat ajar, sitting at the right angle on the floor means I can see directly to the table and I can hear everything they say.
