Inside her.

The timing will be a bit difficult without being able to hear Sarah, but you can see her throw her head back and start to buck her hips a bit. Not an orgasm yet but getting close. You pick up your pace accordingly and feel Grace’s pussy start to tighten around your cock.

You see out the window as Sarah starts to buck her hips hard, her fingers digging into Tori’s hair. You are proud to notice that you were able to time things right as Grace’s body tightens up in waves as another orgasm takes her.

And finally, you.

Two beautiful women cumming before your eyes is more than to push you over the edge. Your orgasm hits you hard as you bottom out in Grace’s pussy, filling her up. “Oh my god!” You both grunt in unison.

Grace pulls herself off your cock and stumbles to her knees. “Christ, I’m not going to be able to walk right for a week after that.”

You look back out the window and see Sarah has collapsed backwards, laying on the concrete around the hot tub with only her feet dangling in. It seems that all three of you have had a very good time.

Grace grabs your spent cock and starts licking it clean, a sensation just on this side of overstimulating. “I’ve got to say, Grace. I think you need to throw more parties.”

She looks up at you. “I think maybe you’re right. I’ll just have to be sure to invite the right people.”
