“Fuck yeah”

"Fuck yeah!" she cried. "Suck my brother's cock you fucking slut!"

Finally I broke eye contact to watch Kara getting eaten out by Amanda for a while. A hand removed itself from my balls and Dawn climbed out of the spa. I was so engrossed in my sister's masturbation that I hadn't even noticed Dawn was playing with my balls while Melissa sucked me off. Melissa continued to bob her head up and down on my cock while Dawn walked around the spa. She stopped above Kara's head, planted her feet on either side of her with her ass to me and slowly squat herself down, lowering her pussy onto her friends face. Kara didn't resist or speak up in any way, instead she started licking at Dawn's cunt.

I couldn't stand it any longer, this was quickly turning into a oral gangbang, not to mention the subtle scent of the pussies being eaten just a few feet away wafting across my nostrils.

"I'm gonna cum." I cried.

Melissa removed her face from my dick and started stroking my shaft with her hand as fast as she could, "I want you to cum on my face."

"Oh yeah," Paige interjected, "cum all over her face."

And so I did. My cock spasmed and started to shoot a torrent of semen across Melissa's face. The first shot hit her in the eye, sealing her eyelid shut. The second shot missed her completely, flew over her head and landed in the water, right in front of my sister. All the follow up spurts landed across Melissa's nose and mouth, coating them in a thick white glaze.

When I was finally finished spewing my load over Melissa, she started scooping it off her face and dumping it in her mouth. When her mouth was full she swallowed the whole load.

"Swallow my brother's cum." demanded Paige, "yeah. Oh... Fuck! I'm cumming!". My sister started bucking against her hand as her climax hit. I could see the cum that escaped Melissa's face lapping against Paige's arm and stomach as she shook uncontrollably from her orgasm.

As my sister started to come down from her orgasm, the other 2 reached theirs. Dawn's hit first, almost immediately followed by Kara. Dawn nearly fell backwards as her pelvis spasmed under the intense pleasure Kara was obviously giving her. Amanda had trouble trying to hold Kara's ass in place as she continued to lap at her pussy.

Finally everyone was done cumming. We all collapsed into the spa and rested.

Everyone just sat there for another half hour or so, before leaving the spa. I gave Dawn's ass a light slap on her way out. Or was it Amanda?
