Shower time

Heading straight for the bathroom you turned on the shower, and after using the toilet you set a towel aside and jumped in, washing the days funk off, as well as the black lipstick on your cock. You'd just startedlathering up when Beth joined you, surprising you but then you remembered you never locked the door. Not saying anything you both just washed yourselves, then you started to wash her back, your sister giving out a small moan as she pressed back against you, her ass rubbing against your cock which quickly grew hard again.

Quickly getting into a rhythm Beth ground her ass against you, your cock slipping between her cheeks and making you moan slightly as she squeezed her cheeks and hugged your cock at the right time. Pulling her close your hand moved from her back to her front, first rubbing her tits and pinching her nipples before slowly moving downwards to her wet pussy. Kissing her you push two fingers into her making her moan into her kiss as you kept humping her ass.

Both of you grinding against each other as you continued to kiss and moan as you pleasure each other, your fingers quickly moving in and out of her as her ass squeezed and flexed around your cock with perfect timing, making your legs tremble a little as you focused on not falling in the shower and in front of your sister.

Breaking the kiss Beth moaned loudly as you groaned into her shoulder, her body tensing up as she came on your fingers, while shot a thick load of cum up her back and between her cheeks. Neither of you saying anything you simply hugged each other for a few minutes before washing again, making sure you were both clean before you left.

"Thanks for the towel" Beth smiled as she wraped it around her and left you standing in the bathroom, realising she'd just used the last clean towel.
