Fill Mary again

Mary kisses you as you cuddle, then she says, "I couldn't help myself with Doe. She's just so sexy and seductive. I've never been with a girl before, but she made it so easy. Even though you got to fuck us both, I hope you're not mad at me for cheating on you."

"Sweetie, as long as I get to have a threesome with them, you can experiment with any girl you want. Explore your bisexuality and have fun. When you're both ready, come to me and we'll all have fun. I love you and I want you to be happy," you say, putting a big kiss on her lips. Talking about this is really turning you on, and your cock is nudging Mary's belly.

She chuckles, breaking the kiss to say, "You're turned on by me being with another girl." She gets on top of you and slips your cock inside her. She holds you deep in her cunt, squeezing your thickness with her muscles. "Well, I was turned on by watching you fuck Doe tonight. I'll share, if you share." Now she fucks you, bobbing up and down, nearly letting you out of her pussy, and then dropping hard to take you to the hilt inside her.

You thrust up into her, and your bodies slap together. You both grunt and moan at the wildness of your joining. You've never seen Mary so horny. Her tits are jiggling deliciously in front of you. You decide to see what the limits of your new rules are.

"So, as long as we have time for the three of us together, is it okay if I have sex with Doe without you? Oh, yeah, just like that." You said that last sentence because Mary sat up straight and bounce rapidly on your stiff cock. The angle squeezed your shaft tighter, and her boobs bounced erotically.

"Oh, baby! As long as you fuck me, and I get to fuck her, I don't care what you do to her alone. Hell, as long as they'll play with me, I don't care who you fuck. Oh, my God, yes, John! I'm gonna come! Fill me with your junk!" Mary's moans started up the musical scale until she hits high-C. Her body explodes in a thrashing orgasm as she keens, trying not to scream and attract attention.

You can't stand it any more, and, as thoughts of the three of you fucking dance in your head, you erupt inside Mary, pounding an ounce of jism into her quivering pussy with long hard thrusts up as she descends. She just gave you permission to fuck not only Doe, but any bi-chick who'll fuck Mary. Your fantasies run wild with images in your head of you and Mary fucking a series of gorgeous women.

"Oh, yeah! Give it to me. Give it to me," Mary says, as she continues to fuck you hard.

You both collapse to the couch, breathing heavily.

"That was so good. Thinking about Doe makes me so horny, I just can't stop fucking," Mary whispers into your ear.

"Seeing you lick her cunt got me hard in two seconds. I think we're going to really enjoy this new aspect of our relationship," you say back to her.

"Now, you better go up stairs to bed before your dad sees us." She licks your earlobe and blows lightly.

"Okay. I can't wait to have you alone again, and to have you both again." You kiss her hard with lots of tongue. You kiss for another minute as your cock slips out of her. Then she pushes you to get you moving.

You stand, your cock dripping with combined fluids.

"Good night, Mary."

"Good night, John."
