Spectacularly, on Paige

At the last second I decided to try something and pulled out as a torrent of steamy white cum exploded from my cock. The first burst hit her square in the ass hole, which was spread right in front of me, the tail end of it going up her ass to her lower back. I thrust forward so my balls pressed into the layer of sperm coating her anus and my dick aimed over her back right as the second wave released. My aim was true and a thick rope of my semen sailed right over her back and stretched itself from her shoulders, across her reddish hair and onto my sister's right ass cheek; hitting its target dead on.

My sister ripped her face away from Dawn's twat as my molten seed struck her naked ass and she looked back at me with shock on her pussy juice smeared face. While she was turning around a third and fourth burst of hot cum splattered against the middle of Melissa's bare back. Followed by a few smaller shots dribbling down her ass crack as my dick came to rest nested between her ass cheeks.

"Sorry Paige. Bad aim." I lied once my orgasm had passed.

Melissa started laughing as she pulled her face clear of my sister's cum splattered ass.

"What's going on?" asked Kara as she and Dawn struggled to look back at the commotion.

"Justin pulled out and blew his load all over Melissa's back, problem is that his distance is so good he hit Paige right on the ass also." Amanda explained with a grin plastered from ear to ear.

Completely spent I moved back and collapsed onto my back. Melissa moved her face over Paige's ass and licked up the semen I had deposited there. Upon seeing that Amanda climbed back out of the spa and started licking up the cum coating her friends back and ass hole, then she moved over to clean the remainder off my shaft and balls. She left the cum in Melissa's hair for her to deal with later.

Once I was all clean, Amanda took position behind Melissa and quickly licked her to the orgasm I had stopped just short of giving her. Paige, Dawn and Kara soon followed, reaching climax for the second time that night. Soon everyone was exhausted and lying on the deck regaining their strength.

We all drifted off to bed and I found my knees hurt slightly from kneeling on the hard wooden deck for so long. I was exhausted and needed sleep, but I was also anxious that there would be no more late night spa sessions since we were heading home the next night.
