When the door bell rang nearly an hour later, Crystal shot her companion a coy smile and crossed the room, her hips swaying enough to ensure Tyler would be watching her bare ass, and unlocked the door. Mourning the loss of her swollen mouth wrapped around his cock, Tyler didn't even protest that she swing the door open completely naked.
It wasn't like the neighbors wouldn't enjoy the sight of her.
What he wasn't expecting more was the girl that stepped through the door. Nearly identical to Crystal, but with darker blonde hair, she stepped through his threshold easily with a smile. Her hair was shorter, cropped around her face and layered longer in the front. Her eyes skimmed the room, resting on Tyler playfully for a moment before sliding to her sister, who'd shut the door behind her and came up to her side silently. Tyler opened his mouth, confused and a little unsure what was going on, his dick stirring back to life at the sight of the girl in the red shirt and tiny skirt. But before he could even ask, she turned towards Crystal and kissed her, moaning lightly as Crystal tugged her shirt up and over her head, exposing her tits.
"Glad you could come," Crystal tossed the shirt to the ground, where it joined the pile of forgotten clothes strewn that night. Taking her hand, she tugged her to the couch where Tyler sat, with little to deny about how he found the situation. "This is Tyler. Tyler, this is Jessie, my sister."
"It's nice to meet you," The words poured from his mouth automatically and he extended his hand, pulling it back the next instant. "So, babe, what's going -"
Crystal and Jessie both took to their knees, one on the couch next to him and the other between his legs. He groaned as their tongues met on his throbbing cock, and ran a hand down Jessie's back beside him, smoothing it over her ass as he tilted his head back in pleasure. She spread her legs open and he traced her cunt, caught up in the feel of a mouth wrapped around his dick and another tongue licking his balls lightly. Crystal reached up to his hand on her sister, and moved it closer to her hole, rubbing his fingers against the smooth skin until Jessie's wetness slicked their hands. She moaned around his cock, and Tyler bit his lip.
"Mmm fuck," He wasn't aware he'd spoken the words, but Jessie moved her head faster in response, bobbing her mouth up and down his shaft, licking the head as she went, virtually throat fucking herself. He slid two fingers inside her pussy as Crystal began to play with her clit, her tongue moving up to meet her sister's on his cock.
