Back home, you meet up with Lydia again

Arriving back home, you put the panties of your neighbour andof the woman from the gloryhole in a hidden place, cautious not to confuse the two. Suc ha mix-up could be fatal, after all.
Then you quickly hop under the shower.
Back in you´re room, your phone vibrates, letting you now you got a new message. Its from Lydia. "Come over, so we can discuss the next steps."

You quickly make your way over, knocking at your door. Hailey opens, and instantly blushes. "Oh..Ethan..hi"
You smile. "Hi Hailey. I came to see Lydia. Is she in her room?"
Hailey looks surprised. "Yes...but John is here as well."
"Alright" You make your way towards Lydias room.
"Do you still want to enter?" Hailey asks. You realize how little she knows about the situation, but you appreciate her beeing discrete about it.
"Yeah" you answer, "It´ll be fine...thank you."

And with that, you open the door. At least John seems startles upon you entering., while the sight of Lydia alone makes your dick press against the fabric of his pants. She wears her blonde hair in a messy bun, and sits on the bed, her back leaned against the wall. She wears a big white t-shirt, her legs are exposed, and at her feet is John, who seems to give her a foot massage. Lydia looks up from her notebook in which she just sketched something, and smiles when her eyes meet you. "Ethan! Hi!" She acts as though she didnt just text you to come over, looking surprised.
"Hi" you say, unsure on how to act.

Lydia breaks the following silence. "John..do you mind giving us a minute? Theres actually something we need to discuss."
John looks sceptically, but agrees, and with one last look at the two of you, leaves the room and closes the door behind him. Lydia smiles. "Alone that will send his thoughts spinning. Anyway, I just wanted to talk with you about last night, and what we´re gonna do next."
You nod, and your eyes fall on Lydias dress, which hangs over her chair. Even from a couple of feet away you can see the stains left by your cum.

"Sorry about your dress." You say.
Lydia looks at you confused. "Are you kidding? This is perfect! You should have seen the look on Johns face! He´ll never be sure if its actually cum or something else, I mean how would he prove it without embarassing himself? I´ll send him to buy me a new one soon either way."
Lydia gestures you to sit down next to her on her bed, where you fucked less than 24 hours ago. "So...I talked with John..and he ad I agree that we´re ready for the next step."
You raise an eyebrow. "the next step being..."
"..You fucking me while he watches, yes." Lydia says unfazed. "Heres the thing. My sister is coming to visit in like a week or something, and it would be easier to do it beforehand."
"Okay..." you say, "So how do you want to do it?"
"We thought for now keeping it casual is the best. You come over for dinner sometime the next couple of days, we eat, then you bed me. In the future, we can get more...experimental."

You agree, and make your way back to your appartement. Just as you arrive, your phone buzzes again.
