My sister's friend Rachel had caught me masturbating once when I came home from college. She not only sucked my dick, but she told me she was fooling around with Gina, my sister. I couldn't get this girl out of my mind after I went back to school. I decided to come home two weeks later and I hinted to my sister that I couldn't wait to come back so I could meet Rachel again.
My parents happened to be gone on a well-deserved vacation that week, but my sister had stayed to go to school, since she never missed a day. When I arrived home that Friday afternoon, I was delighted to see Rachel's car parked in the driveway. I quickly unloaded my junk and went inside.
The house was oddly quiet, except for some light music coming from my sister's bedroom. I unpacked my stuff in my room and made my way to my sister's door. I heard the irritating sound of Kenny G coming from inside along with some soft whispers. I slowly eased the door open a bit and peered inside.
Rachel's naked backside greeted me. She was straddling my sister, naked, and leaning over top her prostrate body. Her oiled hands glided across my sister's back, slowly massaging the honey-colored flesh. She looked to be on the last half of her massage, as Gina had long ago shucked the towel onto the floor. My sister hugged a pillow as she sighed deeply. Rachel's hands worked her back and shoulders taking away any tension that may have been there. She shimmied off Gina and kneeled beside the bed. Her hands began to work the well-toned cheeks of my sister's ass, kneading the flesh firmly and separating the cheeks as she worked them over. Rachel's hands coaxed my sister's thighs apart as they skimmed along the underside of her ass. She worked her hands around the slender legs, gently working the inside of Gina's thighs with her petite fingers.
The short red nails glided along her thighs till she came to the juncture of my sister's legs. Rachel ran a single dainty finger lightly along the smooth skin of Gina's slit, as if testing to see if she was moist. Two of her digits stroked the outer labia softly as the other oiled finger continued its journey up Gina's parted lips. Rachel cooed into Gina's ear as she slipped her fingers back and forth along the length of her pussy. My sister lifted her hips slightly and moaned as Rachel sought out her clit. After a few flicked at the now swollen nub, Rachel removed her hand to again massage my sister's thighs.
She got more oil and warmed it in her hands before working the rest of Gina's legs and small feet. She seemed to take particular delight in rubbing the arches of my sister's feet; Gina moaned her approval, obviously loving the full-body massage from her best friend. I was enjoying the action immensely. One of my hands clutched the doorframe for support while the other stroked my hard cock inside my jeans.
Rachel finished her backside and slowly crawled up Gina's body. Her hands clenched the cheeks of my sister's ass as she lowered her mouth to the juncture of Gina's spread thighs. The tip of her tongue lightly probed the tender folds of my sister's pussy from behind. Gina responded by getting onto her knees, but still kept her upper body on the bed. Rachel's hands glided across the supple flesh of her bottom, before parting the cheeks.
Her tongue worked its way up between Gina's spread behind to rim her ass hole. It probed at the puckered opening before Rachel inserted a finger at the entrance. She blew cool air across the hole as she tried to work her well-oiled thumb into the tight hole, finally succeeding and getting a deep grunt from Gina. Rachel worked the fat digit into and out of the opening and then inserted her middle finger into my sister's pussy. Rachel's finger-fucked my sister's two holes with one hand while rubbing over her clit with the other.
Rachel worked my sister's two holes over and handled her swollen nub until my sister started to pant. She removed her thumb from Gina's ass hole before licking two long fingers and shoving them into her wet pussy. Rachel began to furiously piston her oiled fingers in and out while rubbing Gina's clit; her pussy was slowly leaking its juices all other Rachel's hands and the sheets. My sister came with a loud cry and slumped to the bed. Rachel extracted her hands from under Gina and admired her handiwork. She licked the pussy juice off her fingers and sighed aloud. She lay down on the bed next to my sister and cooed into her ear, her arm wrapped around Gina's slick body. She lightly glided her hand up and down my sister's slick back.
I couldn't take any more of this, so I knocked on the door. Rachel sat up with a start while Gina lay at her side, apparently napping. I eased the door open and poked my head inside. Rachel's startled express turned into a broad smile. I looked at her beautiful, naked body clutching my sister and almost blew my load.
"You look incredible right now." I said softly, as not to wake my sister. She didn't reply, but blushed at the compliment.
"Do you think you could make me feel better too?"
"I can try." She said softly as she got up off the bed. I drank in her nudity as she crossed the room to stand before me. We kissed passionately as she wrapped her arms around my neck. Her bare breasts mashed to my chest and I reached down to cup her ass with my hands. I lifted her slightly and ground her pelvis into the bulging crotch of my jeans, eliciting a moan of approval from her.
