You go home and wait for Jane

It's 2pm the next day and your girlfriend still hasn't returned. You masturbate for the fifth time since you got back, thinking back on what you saw and what you imagined happened next. You hadn't even set foot outside the house last night before you could hear the giggling of the girls, followed by moans.

You're about to cum when you hear a car pull into the driveway. You put your dick away and head to the couch, trying to act nonchalant. After ten minutes you get impatient and check the window. You can see Jason sitting in the driver's seat of his car, seemingly alone. His expression is odd, like he's trying to concentrate really hard. Soon enough, your girlfriend's head appears out of Jason's crotch.

"Of course," You whisper to yourself. Your cock throbs as you watch her wipe the cum off her face.

You return to the couch just in time for Jane to open the door.

"Hey sweetie!" She smiles warmly at you.

"Hey Jane, how was your night?"

"Exhausting! I'm not sure I slept much at all! I'm going to take a shower and then a nap!"

She was gone before you had a chance to reply. You decide to join her in the shower. You creep in, take off your clothes, and open the shower curtain. She already has soap on her face.

"Oh heyyy! Didn't know you would be joining me." She doesn't seem nervous or upset, just surprised. You make your way in and begin slathering down. Your cock remains very stiff. You take the opportunity to press your body against her backside and let your arms envelope her.

"Mmmm..." She coos as you slide your hands over her slick, soft skin. Eventually your fingers make their way between her legs. Your fingers brush against the swollen inner pussy lips, causing her to squeal in pain.

"Ahh! Please, not there!"

You draw your hand away disappointedly. She spins around and gives you a peck on the lips. The lips that were wrapped around Jason's cock not five minutes ago.

"Sorry honey, not today. I'll make it up to you though."

The two of you finish your showers and cuddle in bed, nude. Her head rests upon your chest -- hair still dripping wet. Her hand wraps around your stiff cock and slowly begin stroking you. A moan escapes your lips.

"So what did you think?" She asks with a sweet, innocent tone.

"About what?"

"About Jess and I fucking Jason? She said she saw you in the house watching us." Your cock throbs and her hand begins moving faster in response. Her tone remains so innocent.

"You're what!?" You try to feign outrage.

She giggles, "Sweetie, you're a terrible actor. I know you're not mad."

"I, uh, mmmm..." Her hands do wonders working your cock.

"Did you like watching your girlfriend taking another guy's cock?" She says in a sultry tone.

Your hips subconsciously jerk in response.

"I thought so, honey." She smiles widely and strokes a little more vigorously. "God he made me cum so many times. I'm so fucking sore. Your friend got me off once or twice too, licking my clit. Holy shit, that ginger thing is wild once you get her going. This morning I was woken up to her riding his cock like a pornstar and moaning like she was in heat. Thanks for letting us have her."

It was hard to imagine your girlfriend speaking like this. She's definitely changed and it's driving you wild. You're rhythmically thrusting your cock into her hand now, feeling yourself getting closer.

"We've already made plans for next weekend. Jess and I are going to buy matching collars and wear nothing but that all weekend. He's going to have free use of our holes and we're going to serve him however he wishes. He said you're welcome to come but you won't be able to touch, only watch."

She leans into your ear and whispers passionately into it, "I can't fucking wait to feel him inside of me again. I'm addicted to his cock..."

You begin cumming all over her hand and arm and your stomach. She wipes it off of her arm onto your chest.

"I knew you'd understand, my love." She gives you a quick peck on the cheek, rolls over, and passes out immediately.
