Night comes

That night we had another barbecue and ate on the balcony. We started drinking and chatting, surprisingly everyone kept it very non sexual. Until an hour or so later Melissa yelled out "Spa time!" and stripped all her clothes off.

Everyone else quickly followed and climbed into the spa. Paige was the only one still wearing anything and kept her pants on. She went to go inside when the girls stopped her.

"Where are you going?" asked Melissa.

"To put on my bikini." she replied.

"Oh, come on. Your brother's had his cock out since the second night. Just take your clothes off and get in here." said Amanda, "Besides, I want to see that sweet pussy of yours."

"Me too." added Dawn.

Paige looked at me, then down at my hard dick, hidden by the turbulent water.

"Fine." she said, with a grunt.

A moment later her pants and panties were on the deck and I finally laid my eyes on my younger sister's succulent pussy lips. She was almost completely bald down there with a small triangle of neatly trimmed hair just growing through above her slit. I couldn't stop staring.

While I was busy ogling my sister's crotch as she lowered herself into the spa, Kara started off the activities by sliding a hand under my ass and prompting me to lift myself up, exposing my hard knob to the air where she quickly sucked it into her mouth.

Melissa soon joined in and the two of them shared my dick between them, sucking and licking my shaft while the other played with my balls.

While they polished my cock, Amanda made a move on Paige. I didn't pay enough attention to what happened, but soon I noticed Paige climbing out of the spa. She laid back on the deck while Amanda lowered her face between my sister's legs and began lapping at her pussy.

"Oh fuck yeah," I cried, "eat my sister's snatch!"

The thought was too much for me, as I watched my sister receiving head from her friend I had my first orgasm of the night and began shooting cum down Melissa's throat as she was trying to deep throat me. She wasn't expecting it and choked, pulling herself off me and coughing up gobs of saliva and semen into the water. Meanwhile I continued shooting cum into the air. Kara moved in and took a load of cum on her face before she could get my dick in her mouth where I deposited the last of my spunk.

"Oh my god! This feels so fucking good!" Paige cried out as Amanda flicked her tongue over my sister's clit and pumped her fingers in and out of her pussy.
