Grace says yes

You spend the rest of the day with Adela at the park, wondering what the future holds. Will having a third wheel bring you closer or tear you apart? No matter what, you knew that you were committed. If Adela had any anxiety about the situation, she didn't show it one bit. In fact, the night went by fast, as if it were any other day you'd normally spend with her.

Eventually, Grace comes around to Adela's apartment, wearing an off-the-sleeve sweater and denim short-shorts. She gives both Adela and you a hug before she sits in the couch in between the two of you. There, she says "So, you guys wanted to talk?"

"Yeah. Something like that." You say.

"Well, I've got just one condition."

"What is it?" Adela asks.

"I don't wanna be committed to anything with you guys. I'm single and I'm ready to mingle with whoever I want."

Adela looks to you. "Sounds fair to me."

"Same." You reply.

"How about we kiss on it?" Grace asks.

"Sounds good to me." Adela replies.

She goes for you first, locking lips with you for a deep, passionate kiss. Once she's done, she turns to Adela and does the same. As she makes out with your girlfriend, you decide to rub Grace's leg. This makes her turn to you and say "I think someone wants to do more than just kiss."

"That makes two of us." Adela says.

"Three." Grace replies as she reaches underneath Adela's dress. Then she pulls Adela's panties out of the way, allowing her to rub her slit. Meanwhile, you undo the fly to her short-shorts, and begin pulling them down as Adela purrs to Grace's touch. Once you remove her pants, she spreads her legs, revealing her bare slit. You begin to rub her entrance as she and Adela continue to make out, their purrs occasionally escaping their lips.

Adela then begins kissing Grace's neck, to which she says "Ohh... Is your dick getting hard Oscar?"

"Absolutely."

"Then get it out."

You stand up, giving Grace enough space to get on all fours on the couch. Once your belt is unbuckled and your fly is undone, you pull your throbbing hard-on out and look to Adela, who has ecstasy written all over her face. She gives you a nod so you get behind Grace, who's stuck her plump rump in the air just for you. As soon as your behind her, you rub your tip against the lips of her entrance, before finally plunging inside of her.

"Ohh yeah... Give it to me Oscar."

You start by thrusting slowly, making Grace moan as you do so. Her hand continues to pleasure Adela and soon her lips reunite with hers. They continue to tenderly make out, so you keep a steady pace in hopes that Grace can make your girlfriend cum. Adela can't help but twitch to Grace's touch. Their lips soon part, allowing Adela to unleash a tirade of passionate moans.

"Ahh... Fuck..."

"You cumming?" Grace asks.

All Adela can manage is a nod as she clenches the couch. Her body starts to tremble, before it erupts in bliss. Adela quakes as her legs flail around. Finally, she slumps down on the couch, so Grace removes her fingers from Adela's slit. Grace then sits up and removes her top. As soon as she puts her hands back down on the couch, you begin plowing away with increased vigor.

"Oh fuck! Fuck me Oscar. Fuck me." Grace screams.

You do just that, bucking your hips as she moans with passion. Adela watches on with her fingers jammed inside of her pussy. Despite your relationship with her, Adela watches you piston her best friend with lustful glee rather than jealousy. Sweat begins to pour from your body as lustful cries pour from the mouth of the girls.

That's when you feel your balls begin to tighten, to which you say "I'm gonna cum."

"Oh don't you fucking stop now." Grace declares.

You do the opposite, thrusting faster until you erupt inside of her. Your seed floods her body as she throws her head back and spasms in ecstasy. The two of you catch your breath, before then looking to Adela, who brings herself to her own climax. With the three of you spent, you all decide to head to bed, where you fall asleep with an extra woman in bed.
