Sure......

Jace looked at his hot bodied sister sitting in the bath and smiled.

"Sure." he replied as he pulled his shirt up and over his head. The idea of taking a bath with his sexy young sister was exciting to him as he felt his cock getting even harder.

Kelly smiled back as she looked over her muscular brother's impressive chest and six pack abs. "Damn he's built." she thought to herself as he then slipped off his boots and socks and began to unzip his pants.

"Mmmmm." Kelly quietly moaned as she watched Jace pull his pants and underwear down to his ankles and step out of them. His huge erection was now pointing directly at Kelly and she was impressed with what she saw.

"Wow." she said out loud as she admired her brother's thick cock and huge ball sack hanging between his muscular legs.

Kelly leaned forward allowing Jace to climb into the tub behind her. Jace spread apart his legs allowing Kelly to sit between them with her back against his chest.

Damn she felt good he thought as she moved back and her hair rested back on his shoulder. His rigid cock was now sitting between his little sister's ass cheeks.

"God he's so big." thought Kelly as she felt his huge member resting against her butt.

Suddenly Kelly felt Jace's hands reach up and began to cup her full breasts from behind her.

"Ooohhh yeah." she moaned as Jace mauled her tits and played with her erect nipples.

"I'm so sorry about what happened..." Jace began to say before Kelly cut him off.

"It's not your fault. There was nothing you could have done." she told him as she turned around, facing Jace, and moved her hips over her brother's.

"Kelly what are...." he began to question.

"Shhhhh....Just relax." she said as she reached down and positioned the head of his thick cock against her smooth sex.

Slowly the sexy 20 year old began to lower herself down onto her big brother's throbbing cock.

"Oh God Kel..." he moaned as he felt her tight little pussy wrapping around his shaft.

Kellly took her time as she allowed her body to adjust to her brother's size and she lowered herself further and further down on his fuck tool.

Finally he had bottomed out against her cervix and the sexy minx began to slide herself up and down along his stiff prick.

"Oh yeeees." she yelled as she felt her first orgasm begin to come over her and her body began to shake. Her pussy closed even tighter around her brother's massive man meat as she came.

"Oh yeah...." Jace yelled, "I'm cuuuuummming!!!!!!"

The bath water splashed over the sides of the tub as both siblings came together and Jace filled Kelly's fertile womb with his hot seed.

They held each other for a while before drying off and heading over to the master bed.

What's next?

Round 2, they get **** the next day, a bump in the night or ?????
