Sibling Bonding

Nico needed a few minutes to get back into it so he looked at the sisters. "Can you two give me a show like you were doing before?" Nico asked them.

"Of course." Gamora pulled Nebula into a kiss, pushing her tongue into her sister's mouth, tasting the left over cum that Nebula had in her mouth.

Nebula let out a whimper as her sister made out with her, Nico watched and bit his lip, he couldn't believe this was happening but he was watching it first hand, he felt himself getting hard again but he didn't care, he just sat and watched as Gamora groped her sister's breasts and Nebula ran her fingers through Gamora's hair.

Gamora kissed down Nebula's chin, down to her chest, licking her nipples and kept moving down until she made it to her sister's pussy, which she started to eat enthusiastically.

Nico bit his lip and slowly stroked his cock, enjoying the show in front of him.

Gamora stopped and looked at his cock. "Ready?' She smirked.

Nico nodded. "I want to be on top." He told them.

"Okay, Nebula, lay down and spread your legs wide." Gamora told her sister who followed her instructions, laying on the bed and spread her legs.

Nico got between her legs and rubbed his cock against her wet pussy, he bit his lip as Nebula whimpered.

He slowly pushed into her with Gamora leaning on his bed, stroking his chest as he started to fuck her sister.

"She likes it slow, them rough." Gamora whispered into his ear which made his cock twitch, imagining the lesbian action between the sisters.

Nebula gripped the bedsheets as he thrusts faster into her pussy.

Nico felt Gamora push his head down as he was now face to face with Nebula, the two shared a deep kiss while Gamora went down and like Nico's balls while using one hand to finger her sister's ass.

Gamora had been in the SHH with her sister for over a year, Gamora was a popular choice, so she normally got picked and fucked, she didn't like at first but soon came to enjoy it and explored kinks whenever she got the chance, her sister Nebula wasn't popular, the two bonded during they're time here and Nebula became the little sister.

She always wanted a threesome with her sister and now she was getting it.

"Fuck I'm cumming again!" Nico came inside Nebula and with Gamora fingering her ass, Nebula had the most intense orgasm up to date.

The duo slumped onto the bed and took shallow breathes, Gamora got up and walked to the mini fridge and took out a bottle of water, she began to drink and watched the two inexperienced people rest, she smiled, maybe next time she'll have this Nico all to herself but for now he looked spent after cumming twice.
