On her face.

"You know, Sarah, I'd really like to cum on your face instead of in your mouth."

She grins, mid-lick on your cock. "Your wish is my command."

Done with her foreplay, she starts work on your climax in full. She uses her tongue to play with the tip while using her hand to pump your shaft. The twin motions feel amazing and you feel your climax building.

"God, Sarah, yes. Keep doing that," you say.

Outside, Graceseems to be getting close too. She's reached up and has started playing with her own nipple while Tori works her pussy. Her head is thrown back and her eyes are closed. Even though you can't hear her moans, you can tell she's about to cum alongside you.

Part of you - what little of your brain is still being supplied with blood - still can't believe that this is really happening. You're looking out on two hot women fucking in a hot tub while a third hot woman sucks you off so you can cum while watching them. However this plays out with Grace and Tori after this is over, you know you want Sarah to keep fucking you on the regular. She's way more open than her shy exterior implies.

You see Grace start to hit her orgasm outside. Her body starts pulsating with pleasure running up and down her body. Her fingers dig deep into Tori, causing the girl to wince. She doesn't stop her thrusting motion, though. Sarah's stellar technique brings you to climax at almost the same moment. You grip her hair and pull her face back. She keeps pumping your cock and you start to shoot your load all over her beautiful face. Your cum shoots out in a series of bursts splashing across her eyes, cheeks, and her closed lips. Some errant globs land in her hair and others drip down off her face and onto her tits.

Once you're orgasm fades, Sarah makes a show of cleaning up your cock with her mouth. While she takes care of that, you look back outside. Grace has essentially collapsed in a pile of Jell-o as Tori kisses all over her body, face, and lips.

“I think Grace needs to throw more parties," you say.

"Agreed," Sarah says. "Now can you go get me a towel, please?"
