Hubby had a long day’s work and said he was going to go for a long soak in the shower, and he had only been in there for a couple of minutes when my sister turned up.

My sister said she could hear water flowing so I said yes hubby is in the shower, laughing she said ooooh I could do with a shower so I said help yourself I’m sure he won’t mind.

So my sister undressed and wrapped a towel around herself, and went towards the shower room. I followed along behind to see his reaction, he was standing there underneath the water flow and I could see through the door his big cock as the water flowed over it and trickled around his balls.

My sister opened the cubicle door and hubby’s eyes shot open, and he found himself looking at my sister with a towel wrapped around her breasts and hanging down to her thighs.

Both looked at each other and hubby’s big cock started to harden, and the water was cascading down his body and my sisters eyes in the meantime had dropped to hubby’s crotch and his hardening cock.

Stepping into the cubicle she pulled the door shut and then pulled her towel open revealing her large pert breasts with slowly hardening nipples and her shaved pussy with her landing strip of hair.

My sister stepped under the water letting it soak her hair and roll down her breasts, hubby’s cock got harder and with that she reached down and took his big cock in her hand and began to stroke it.

Hubby reached up to her breasts stroking them smearing soapy water over them so they became slick and slippery. Reaching behind her he ran his hands down her back sending a small shiver down her spine before he reached her bum which was a lovely couple of hand fulls which he gave a squeeze.

I could see my sister was enjoying the sensation of her nipples rubbing on his chest, with the water streaming down between them, she decided she wanted a closer look so slid down to her knees until hubby’s big cock was in front of her face and began to play her tongue around his helmet.

Hubby leaned back and enjoyed the view of my sisters lips slipping over his cock, my sister was in her element sucking on hubby’s cock her fingers playing with his balls and the water spraying onto his shaft.

After about 5 minutes hubbyreached down and pulled her up, as he wanted a taste of her juices. Sinking to his knees he found my sisters trimmed pussy, already her lips had swollen a little pushing her clit out.

My sister opened her legs slightly letting hubby get access to her pussy, and hubby started by licking around her lips before nibbling on her clit, one of his fingers parted her lips and played with the opening.

My sister quietly groaned enjoying the sensation and gyrating her hips so her pussy was forced against hubby’s face. Hubby moved his tongue to her opening taking a few drops of juice that trickled out, he prodded his tongue into the opening flicking it in and out driving my sister to grab his head and push it into her crotch. My hubby grabbed her ass pulling her to him, and stroked a finger down her arse crack.

Hubby now wanted to plant his cock deep inside of her, and she was not about to object, so as hubby stood up she turned and bent over at the waist, presenting her perfect ass to him. She reached back and parted her lips her lovely dark hole looked so inviting, so hubby stepped up and pushed his hard cock into her awaiting pussy.

My sister let out a little gasp at the sensation of his cock running deep into her, as hubby leant back against a cubicle wall she supported herself with her hands on the other wall. This position allowed hubby to thrust deep into her as she reached back and played with her clit, the water ran down her arse crack onto the top of hubby’s cock adding an extra bit of lubrication to her already wet pussy.

My sister then started pushing back hard against his cock and she rotated her hips getting his cock rubbing all the right spots. So I watched my hubby and sister fucking like this for about 25 minutes, whilst I fingered my own pussy.

I could see her pussy clamped along his big cock, so as her muscles rippled along his length she orgasmed. With her body quivering hubby sped up his thrusts, until he shot his load deep into her pussy.

Hubby turned the shower off and my sister turned to him again and pushed a couple of fingers into her pussy, she licked one side of them tasting their juices then put her fingers to hubby’s lips so he could taste them too.

They came back into the kitchen where I was making coffee, both looking utterly satisfied with their shower.
