Just start fucking.

With an offer like that on the table, your cock is at full strength again within seconds. Sarah doesn't skip a beat, diving between Rachel's thighs.

"Oh, Sarah!" Rachel squeals as her friend's tongue darts out at her slit. She holds her head in place and gasps with pleasure at the feeling.

You tap Sarah on the hip and position yourself behind her. She takes the hint and raises her hips, presenting her vagina to you. Rachel flops backwards on the bed, legs splayed as Sarah eats her out. You run the tip of your cock along Sarah's slit, then push into her. She moans into Rachel's cunt as you fill her from behind. Once your cock is fully sheathed inside her warm pussy, you grip her waist and start fucking her in quick, deep thrusts.

Rachel's breathing starts to get heavier. She stares into your eyes from across the girl sandwiched between you, and you see the raw, untamed lust on her face just before she squeezes her eyes shut and cries out in orgasm. "Oh fuck, you two!" she shouts as her hips grind up into Sarah's mouth.

Sarah, it seems, is not far behind, as her pussy clamps down on your cock and holds it there, deep within her. Her passage ripples around your cock as she screams into Rachel's groin. Panting, Rachel leans over Sarah and kisses you on hte lips. As she does, you let your own climax wash over you. You moan into Rachel's mouth as you cum into Sarah's clenching cunt, sending your semen deep into her womb.

As you come down from your respective peaks, your cock slips out of Sarah. "Damn, Jack," she sighs, "Knock a girl up, why don't ya?"

"Sorry," you chuckle. "Also not sorry."

"I want next," Rachel says. "If Sarah gets a baby, I want one too."
