Glenna wants to stick to the plan

Glenna suddenly grabs one of my Fionn’s hands and pulls it from my breast to place it on her own.

“Don’t limit yourself to just one set of boobs, Fionn. Try mine as well.” She tells Fionn.

Looks like Glenna is sticking to the plan. Oh well. Tough luck for Fionn.

“Fuck, just thinking about you having sex with me and Glenys is getting me so hot.” Glenna says, further teasing Fionn.

Then I see Glenna bring one hand to her crotch and start caressing her pussy.

“You see this, Fionn? This little hole is getting hungry for your meat.” Glenna continues.

I can’t believe how lewd my sister is being. And as her twin, she is expecting me to go along with her. Oh man, this is going to make me feel so embarrassed.

I spread my legs a little and bring my hands to my pussy as well. “Same for me. I can’t stand how empty my hole is now.” And despite how embarrassed I am doing this in front of a guy, I slide a finger inside my pussy and start fingering myself.

I close my eyes and start imagining that instead of my finger, it is Fionn’s dick that is in my pussy. Oh man, I actually could use a dick inside there right about now. It also surprises me at how lewd I am right now, but somehow I don’t seem to mind Fionn seeing me like this. I guess Fionn is of the same mindset as me as he grabs his dick and starts masturbating as well.

“Shit, you two are so hot. I bet the both of you can make me go all night.”

Oh yes. If necessary, I will suck Fionn’s dick myself and get him hard again after he seeds Glenna. But suddenly Fionn gets a surprised look on his face and lets go of his dick.

“Something wrong?” Glenna asks.

“It’s nothing, I was just close to orgasm.” Fionn admits. “I’ll be fine if I don’t touch it for a bit.”

In a flash, Glenna is at Fionn’s side again, hugging his arm. She brings her hand to his dick and stats jacking him off very quickly.

“Come on, Fionn. You’re not going to tell me you are one of those guys who goes off early.”

Time to give Glenna what she’s been wanting. I retake my position on Fionn’s other side and grab his dick as well.

“You can hold it in, Fionn.” I say. “I believe in you.” Despite trying my best at milking his dick so it would all come out.

Fionn looks down all worried and concerned and says, “No, girls. Really. You got to stop. I’m about to blow.”

Glenna rubs her breast against Fionn’s arm and moans “Ahh, Fionn. Are we too much for you? Are we going to make you blow your load early?”

I’m so sad for Fionn. All he wanted was a fun Samhain and me and Glenna are going to ruin it. But making a guy cum like this also makes me feel powerful and in control. I can’t help myself. I start rubbing my breast against Fionn’s arm as well. “Please, Fionn. My pussy wants your dick so bad.”

And just like that, Fionn’s dick starts throbbing uncontrollably in my hand. I look down and see his white stuff leave his dick and fall onto the ground. Some of it lands on my fingers, but most of it lands on the forest floor. And while a little bit of the white fluid lands on my hand, too much of it is ruined as it drips on the forest floor beneath us. I can't help but feel a little disappointed.

Glenna starts laughing and says, “Oh, wow. You came this quickly? Man, Fionn. If this is how quickly you go off you won’t be able to satisfy one woman, let alone two.”

I chime in saying, “Yeah, you’re gonna have to last longer than that, Fionn.”

“… Wha … What the fuck?” We hear Fionn say.

“Oh well. We better go and find us a guy with more endurance.” Glenna says as she starts walking away. “Don’t worry, Fionn. You can keep your necklace. Let’s hope you get hard again in time for the next girl. Nyahahaha.”

I follow my sister and quickly turn back to say, “Sorry, Fionn.” Then Glenna and I both disappear into the forest and leave Fionn behind.
