Swapping.

The next evening, the four of you sit down and chat for a few minutes, discussing the events of the day before. Trish takes a pair of small white collars out of her purse. “Okay, everyone,” she says, standing up and bringing her hands together. “Up until now, we’ve only seen a little bit of each other and it’s kind of impersonal. Let’s get these clothes off so we can enjoy each other’s company better.”

Excited at seeing three nude women, you strip quickly, but are still the last one to be naked; Stoller hadn’t needed ordering.

Looking over the three of them, you’d say Phoebe is the most attractive, followed closely by Trish, although Stoller is by no means unattractive.

Trish steps over to Stoller, who is hiding her pussy with her hands, and attaches one of the collars to her neck. “Trish?” Stoller asks. “How far is… are you taking this? I mean… a collar?”

“That’s up to you, Millicent. Should I stop?”

Silence.

“Now, Phoebe, this one is for you. John? Make sure there’s enough room between the collar and her neck for you to fit two fingers comfortably.”

You take the other collar and put it around your girl’s neck. Phoebe shivers a little excitedly, but doesn’t resist.

Trish continues, “The collars are white and don’t have patterns on them so they don’t violate the school dress code; I checked. Now, John, your Phoebe is a lovely pet. Would you mind if I played with her for tonight? I’ll be happy to loan you Millicent.”

Phoebe starts to object, but you overrule her. “Certainly, Trish. Where would you like her?”

“Why don’t we sit on the couch here. Hang on.”

Trish takes a double-headed dildo out of her purse, lubes it up, and slowly pushes it into herself. Leaning back on the couch, she starts to pull Phoebe over.

“You know, Miss Stoller,” Phoebe says, as the two girls start to position themselves. “A lot of us girls have noticed that you’ve been looking a lot prettier lately- aahhh…”

As Phoebe lowers herself, you explain, “Yes, yes she does. Come on, Miss Stoller, your turn. Sex improves blood flow, which is good for the complexion. Now try to relax…”

Stoller doesn’t resist as you lead her over your cock and position her, and she even lowers herself onto you without being told to. Once your penis is all the way in her, you reach your arms around her waist, pull her close, and kiss her on the lips. The kiss isn’t returned, and she looks down and away. Taking Trish’s hand in yours, you kiss Stoller again, slipping your tongue between her lips. She begins rocking awkwardly up and down, but doesn’t kiss you back.

The four of you gradually set rhythms as the “girlfriends” start moving up and down. You aren’t able to get Stoller to really get affectionate with you, but you do hear Trish and Phoebe reach orgasm a few times. Finally, Stoller’s breath begins to quicken as you push up into her, massaging her firm, round breasts and her back. You’re barely able to hold up coming until just after she does. This time when you kiss her, she returns it, even letting her tongue touch yours for a moment before she backs away.

At Trish’s instruction, Phoebe and Stoller lick your penis clean, before you all get dressed.

Phoebe and Stoller continue wearing their collars the next day without comment or complaint.
