Author's Note: This is a spin off of the story Not What It Seems. It can be read as canon or independent.
This story is based between the first and second chapters of the main story. It was one of the many ideas that came to me while I was trying to work on the recently posted chapter 5 (still waiting for it to be approved as I post this one) and I just had to let it happen. I've been waiting to post it until after I added the 5th chapter because I wanted to work on Jeremy and Valen before letting Robert have his way with her one more time.
It's also a little apology for those who wanted a different outcome than what happened in the main storyline 😅
++++++
Robert wasn't sure what woke him up, but the warmth of a body against his own kept him awake. For one brief waking moment he forgot about finally getting to fuck his sister-in-law, but as the memories slowly filtered in his cock stirred at the realization he was still in her bed.
There wasn't much lighting due to it still being dark out, but his eyes could vaguely make out the shape of her passed out figure, laying on her back with nothing covering her as neither of them had taken the time to cover up before passing out after he had fucked his frustration out of her. He hadn't even let her shower before bed, wanting to ensure his sperm stayed safe inside where it belonged; it pleased him to know she was covered in
their
mess in
her
marital bed. Her hips though, were still raised by the pillow he had made sure to slide under them before he passed out beside his unconscious (by then) partner.
Her moans and cries echoed in his mind, sending more blood rushing downward as he also thought about how tightly her body had gripped him when he pumped her full of his cum. Fucking her had been better than any of his fantasies, and his back stung in a good way from where her nails had scratched at him in the heat of her passion. And...his brother was gone for a few more days, leaving him to take full advantage of his sister-in-law during her most vulnerable time and do what he could to endure Jeremy came home to a pregnant wife.
It amused Robert, that she had gone from telling him,
"Robert stop. You can't get me pregnant, Jeremy would lose his shit."
to later moaning for him,
"Please baby please knock me up. I want to be a mommy so bad. I want to feel our son growing inside me, I want to know my stud filled me up."
It wasn't fair that Jeremy had managed to land himself such a needy bitch, he would never be able to keep up with her. Both brothers had a high sex drive, but Robert was almost never satisfied and last night he had actually fallen asleep feeling truly
empty
. And to her credit, she had laid there and let him just do what he wanted even when she wasn't able to keep going herself, and when he could see on her face it was starting to hurt, she still held onto him and urged him to take what he wanted from her. He didn't do love or romance, but she was the perfect bedroom partner. She was wasted on his brother.
...She was also still naked in bed with him...
He turned onto his side and found her knee with his hand before he slid it higher, smirking to himself when he found the dried evidence of his success on her thigh, and kept going until he found what he was after. His cock bobbed when he felt how slippery her pussy still was a couple hours later, and how puffy her lips were from how insatiable he had been once he got inside of her.
He had done that to her, not his brother. That was his cum still stuck inside her, hopefully planting his child in his sister-in-law that Jeremy hadn't been able to knock up yet. And, thanks to the fertility drugs she was on, and with her actively ovulating, she had unknowingly (as far as he knew) made herself perfect for him to be able to live out his fantasies...and he fully intended to.
His cock was starting to ache by the time he moved to kneel between her partially spread legs, pushing them further apart to make room for himself. He held his shaft as he glided the spongy cock head up and down the slightly parted seam of her puffy lips a few times before he eased his way back inside. A pleased, relieved sigh escaped him as her pussy reflexively squeezed and welcomed her stud back in its soft, velvety warmth. But the welcoming squeeze tightened even more from Valen's surprise when she was awakened by his invasion. "Fffuck that's good."
"Robert...?" Her sleep dazed voice was confused as she looked at Robert's silhouette in the dark room.
