The Sweetest Taboo

"Get. On. All. Fours."

She saw her sister get onto the bed on all fours, then reached down to pull down her pants. She got on one knee behind her sister, holding onto her dick and aiming it for that pussy. After a bit of an assist, she could feel the warmth envelop her tip. Little by little, she eased her way into the warm, wet walls, feeling them squeeze with each stroke in and out. Finally, she managed to hit bottom, and began to slowly pump. She got her rhythm going with long strokes, steadying herself with one hand on her sister's arched back. Feeling herself a bit, she wrapped her hands around her sister's hips, her talons digging into her sister's flesh, her platinum tresses beginning to stick to her as she started pumping in abandon. That wonderful, tight pussy was rubbing against her so right, tugging at her, milking her in response. She could hear her sister moaning off in the distance, each stroke making her want to go harder, make her to come hard as the loud slap of flesh hypnotized her.

"Jimmy!"

"Wh-what sis?" Storm said as she was broken out of her trance.

"Phew! I knew calling you that would get our attention," Tisha said, almost out of breath. "Hey, can we change angles? I'm hitting the wall with my head here."

"Oh, OK. Lay down lengthwise on the bed," Storm said as she pulled out of Tisha, then got off the bed for Tisha to straighten out. She then climbed in between Tisha's legs and pifted them up on her shoulders before gently guiding herself into the opened, slick gash between her sister's legs. She pushed in all the way to the bottom, then rocked back a bit on her knees before starting to stroke out, htting the G-spot with her huge member. Storm looked down and just rocked her hips back and forth, making her sister gasp in pleasure. She kept up the motion, loving the way that cunt squeezed on her more and more until it went a- flutter, coating her balls in a thick layer of juice. She blindly groped out her sister's tits, rolling and pinching the nipples and getting a yelp out of her as she kept up that motion before stopping and bending down to suck a nipple.
