You play with her

She is turned towards you with her legs on the chair and bunched together. You place your hands on her knees and begin to separate them as you want to return the favor of giving her own orgasm. You are like a wild beast in heat at your hands pull her legs apart as she watches you move your hands closer to her soaked pussy. With her legs now separated: one leg hanging over the chair and the other with the foot on the ground you begin to gently roll up her skirt. She is panting in anticipation as she is **** for the relief of an orgasm and the excitement of your touch upon her pussy lips. You take a moment to stare at her perfectly waxed lips covered in shimmering juices. You can see her lips unfolding themselves in response to how close your fingers are on her thigh and her face is begging for your fingers to go to town. You have never done this before but enough years of watching lesbian porn has prepared you to give your sister exactly what she needs.

You rub your fingers along the outside and feel just how soaked her pussy really is. She begins to purr and quietly says, “Mmmmm…that’s very nice, bro. I really enjoy a good tease.” You don’t continue to pet up and down along her soft, juicy lips until you find her clit at the top. You give it a gentle pinch as she lets out a moderately loud moan but catches herself with her hand over her mouth. You continue to pinch it while your other fingers trace her pussy lips to find her opening. You quietly ask, “Are you ready sis? I want to return the favor for you.” She had her hand on her mouth and could only nod at you. Your lubed up fingers enter her pussy without any problems as her muffled moans can only be heard by you two. You push in as far as your fingers can go and you pull them back out. You decide to add a third finger to give it more girth and push them in once more and her moans are much louder now.

You decide to continue with this as your fingers go at a moderate rhythm of in and out. You could hear her stifled moans and surprisingly the gushing of her pussy juices as your finger fucked her. You could hear her muffled cries “Ohhh…fuck…just like…that…bro…” You continue this while increasing the speed ever so slightly every couple of seconds. You are no longer pinching her clit but instead now fully rubbing it in circles. You are watching your sister’s body spasm in response to your changes as you feel her body thrusting onto your fingers as well. She is moaning fairly loudly even through her hands and you can see in her eyes that she must be getting close. She suddenly grabs your arm and brings her mouth into yours as she moans through her orgasm. You two share a kiss for minutes as she enjoys her orgasm. She finally says, “Oh fuuuuuuck…That was incredible, bro…Ohhh! Oops I made a mess on the chair…where am I gonna sit now?”
