Fuck Rachel next, of course!

At Rachel's eager, lust-filled words, your cock never even wavers. Sarah rolls over to one side between you and Rachel, still in a post-orgasmic haze.

"You two have fun," Sarah sighs, rubbing her dripping pussy. "I just need a minute."

You slide across the bed and pull Rachel close, pressing her tits to your chest and kissing her deeply. She lets you probe her mouth with her tongue as she melts into your embrace. Then she wraps her hand around your cock and rubs back and forth. She presses against your chest with her other hand and pushes you back. You lay back on the bed at her command, your cock jutting up before her.

Rachel positions herself on top of you, spreading her thighs over your groin. She holds the base of your cock in her hand, guiding it to her opening. She keeps her other hand steady on your chest for stability as she lowers herself down. Your cock parts her slit, still slick as it is from fucking Sarah.

Rachel moans as you fill her. Her face is a mask of pleasure as she bottoms out on your cock. She smiles at you and squeezes, making you gasp as her canal grips your cock. Then she starts to ride. Her cunt is a marvel around you, sliding up and down as you lay back and enjoy. You are still coming down from your intense orgasm with Sarah, so you are content to let Rachel pleasure herself on you as much as she wishes.

As you feel her cunt ripple around you, you know she has reached the first of many orgasms on your cock. She squeals in delight as she bounces over you. You reach around and grip her ass with both hands, guiding her bucking hips.

"Oh yes, Jack, yes!" she pants as she fucks you. "Yes, yes, YES!" She quakes in a second climax.

Then a pair of hands reach around from behind her and take hold of her jiggling breasts.

"Fuck her, Jack," Sarah says, propping her chin on Rachel's shoulders. "Fuck her hard and put a baby in her, like you did to me."

"Yes," Rachel gasps. "Yes, fuck me hard and knock me up. I want you to cum inside me. OHHHHH!!" She melts backwards into Sarahs arms, never stopping her hips from grinding into yours, keeping your cock firmly inside her through her third orgasm.

"After we graduate," Sarah says, running her hand down from Rachel's tits, "we can all move in together." She starts to rub Rachel's clit, just above where your cock spears into her. Rachel thrashes in her arms, cumming harder than ever before. Her cunt's grip on your cock starts to draw your own orgasm closer. "We can all live together and be a family," Sarah says. "And you can fuck us any time you want, Jack."

"Ohhhh yesssssss," Rachel gasps through her steady climax. "Any time..."

"You gonna cum?" Sarah teases you. "You gonna knock her up for me?"

"Yeah," you grunt, actively thrusting up into Rachel now. "I'm gonna cum... right... now!" Your cock explodes inside Rachel's clenching vagina, spraying your sperm into her waiting womb. She screams as she feels you burst inside her, then falls limp in Sarah's waiting arms.

"Oh, that was the hottest thing I've ever seen!" Sarah laughs as your cock continues to twitch in Rachel's pussy. "No way we're not both pregnant now!"
