It's you who has to help her

Trish is definitely horny and the wolfish look she's got as she gets behind Bethany has you worried. You can tell that the massage is helping, but Beth is still too worried to go further. Then a plan comes to mind. You hug Beth and say, "Hang on." The way you say it the words sound like an interesting idea just popped into your head. But you're also looking straight at Trish when you say it.

Your girlfriend nods, message received. She mouths the words, "Lead on, babe," and that smile returns - waiting to see how you plan to do this.

"I know how to take care of all that stress," you whisper. "You love touching this belly of mine, hmmm?"

Bethany's eyes open again and, sure enough, she looks worried that she's been found out.

"Here," you say before she can start to apologize or, worse, pull away. You put your hands on her waist and pull her against you. She freezes up once more, now with her belly pressed up against yours. Only the thin fabric of your shirt, the sheer fabric of her blouse and that belly chain are between your belly and hers.

You whisper, "I love it when people touch by belly." Right now the deep warmth of your tummy is spreading into her, you can feel it. The extra heat of a developing baby is soaking into Bethany's belly. When she finally moves again it's only her hand, gently running along your flank.

"Yeah... that's nice," you tell her. "Do you want to be even closer?"

"Imagine if we swapped places," you say as you gently stroke the small of her back. You deliberately push your belly against hers so your roundness interlocks with her slender, concave stomach. "Imagine if you were the one with four and a half months worth of baby belly to share with the world."

Beth's breath catches.

"Yes, it feels so good, doesn't it? You love feeling your husband's baby growing inside you. You love sharing it, you love when your friends touch it. You're finally starting to get through to Jane - she's so shy that she doesn't believe how good this feels to you."

Bethany keeps stroking your flank, not saying anything.

You wait, letting Beth get more and more comfortable. Then you ask, "Would you like to be even closer?"

She nods. You think this little cutie is starting to get eager.

You shift backwards just a bit, just far enough that you can undo the buttons on your shirt. The sexy garment has done its job, so you open the front and allow your now naked body to press against Bethany. You give her a smile and say, "Your turn."

She mirrors your actions, shifting back just enough to unbutton the sheer blouse.

Trish gets involved, helping to slip both garments away. Then Trish undoes the top of your swimsuit and, with a little work, gets it up and over your head.

A bit more work and Trish gets rid of Bethany's bra the same way.

You wrap your arms around Beth and draw her close. Your naked bellies press together, now only the belly chain between you. And Trish takes care of that next, pulling slowly but inexorably so the hot metal links slide from between you one by one.

With the two of you so close it's actually hard to tell where your belly ends and hers begins. You let out a happy moan and whisper, "Isn't that lovely?"

"Yeah," Beth whispers back.

"Thank you for sharing your pregnant belly with me, Beth," you whisper.

"Oh, but..."

"No, I want this. I want you to understand how beautiful it is to share your belly. Having someone else right there, rubbing... touching... feeling you. It's divine." As you tell her this you run your fingers over her skin.

It takes a while, but as you keep gently teasing Beth she starts to respond. Her long fingers start to explore your belly in earnest. Pretending it's her tummy that's getting bigger has finally removed some of her inhibitions. Now the hungry eighteen year old wants to sample what she's been missing.

You take the opportunity to indulge in all the wants of your male self. You rub your face in Bethany's soft, brunette hair and drink in the scent. You brush your fingers along her spine, you even tease the sides of her torso, just close enough to feel the start of her nice, firm breasts.

It takes quite a while, Beth is so slow to start. But once her motor is running she's forgotten almost everything else. She's the one who decides to kiss you. It's her hand that tentatively reaches down, feeling the lower swell of your belly. And then it slides lower to run along the edge of your swimsuit bottom.

"Mmmm, don't stop," you whisper. And she doesn't! Out of the corner of your eye you see Trish, grinning like a maniac. The tent in her pants would be impossible to hide.

"Now, what was it you called me?" you muse. "Oh yes, 'Beautiful young mother'. I like that."

Bethany moans and you slip your hands inside her tight wrap skirt. She doesn't complain when you slide them into the band of her panties and work them down her legs.

You say, "A beautiful young mother like you knows there's only one thing that feels better than cuddling with a dear friend."

"Oh?"

"Feeling your husband... connecting with him..."

Bethany's eyes widen as Trish's meaty goodness slips inside her skirt, between her thighs and homes in on her virgin sex.

You know Trish has stopped, her cock resting against the gates of paradise. You whisper on more time to Bethany, "Do you want to feel what it's like for me?"

Without hesitation she lets out a little, "Yes," and nods vigorously. Damn, she's horny.

As Trish slowly feeds her snake into Bethany's tight, wet hole you get to feel it through your belly. Beth has such a flat tummy that you can feel the tip of Trish's manhood as it burrows deeper and deeper into your new lover's body. As Trish starts to rock back and forth you close your eyes and imagine what's happening inside Beth - the long, hot passage gripping your husband's shaft, the thirsty womb just waiting to suck up all Trish's virile swimmers.

Being here, grinding up against Beth as your husband makes a woman out of her - it's the greatest feeling you can imagine. In fact, you even cum - the raw sexual energy, the knowledge of what this will lead to, it all wells up inside you and you moan deeply. Then you stare into Trish's eyes. She smiles - she knows exactly what just happened.

As you feel Trish pick up the pace, ready to seed this lovely girl, you give Bethany a deep, sensual kiss. In return, she practically sucks your tongue right out of your mouth.
