Finish what you started with Amy

You turn to Ellen and kiss her deeply, running your hand up her thigh until your fingers are pressed against her warm pussy. "I'm gonna fuck you so hard, Ellen," you whisper in her ear. "...After I make Amy cum on this dick."

Ellen pouts, then smirks. "I guess that's only fair, since Amy made you cum you owe her an orgasm."

"Damn right," Amy says. "Don't pull out until I cum this time, Scott."

You kiss Ellen again, letting your promise linger on her lips. "I'll be back for you," you tell her.

You turn to Amy and run your hands up her parted thighs. You keep rubbing your palms up her hips and sides, until you have her wonderful tits in your grasp. You lean in and kiss her on the neck, collar, and lips. She moans as she feels the tip of your cock brush against her pussy. "Fuck me, Scott," she says, then she grips your buttocks, and pulls you into her. She moans, then wraps her legs around you, pulling you deeper into her as you start to thrust. You reach a hand between you to rub your thumb against her clit.

Fortunately you just came a few minutes ago, so you have stamina to spare this time. Amy's moans grow deeper and more guttural. "Ungh ungh ohhhh..." she moans into your ear as she closes in on the climax she seeks. "Ohgod yes, fuck fuck fuuuuhhhck..."

"Amy's about to cum," Ellen whispers into your ear. "Fill her up like the cumslut she is, stud."

"Mmmm..." Amy shudders, then spasms under you as she orgasms violently. Her cunt squeezes your cock, and you feel your own climax stir.

Ellen runs a hand up and down your back, then slaps you on the ass playfully. "Don't forget to save some for me, Scott."

You buck your hips against Amy's, bottoming out inside her as your orgasm strikes. Your cock fires ropes of sperm into her quivering depths, stretching her orgasm out longer.

Finally, she collapses back, letting your cock slip out and spurt one last rope of semen onto her red-tufted mons. She smiles in a happy orgasmic daze as she shakes with periodic aftershocks.

You let yourself flop down onto the bed beside her and both of you lie there for a moment, breathing heavily together. Your cum trickles out of Amy's pussy. Your cock, shining with Amy's fluids, remains hard.

Ellen respects the afterglow for only a few seconds. Then she jumps you, straddling your hips, rubbing your cock against her vagina.

"Mmm... that was so hot watching you and Amy go at it," she says. "Are you ready, Scott? I'm going for a ride."
