Yep sex now

Soon he sat Annabeth on the bed seperating from her extremely sexy body.

"Anna, i'll make this the best experience ever" Shiro promised.

[Ding! +1 libido for lusting after yout sister!]

Ignoring the pop up he could feel something change withint him, at least, in his dick.

He watched as annabeth slowly but sensually way, her large breasts were hugged by her black lingerie, her bra and panty underwear really enhanced her sexual appeal.

He then knelt down and took off her panty, he pumped a finger inside of her pussy giving it a test to see just how senstive she was.

"Hmmm~" Annabeth let out a sexually enducing moan as he contintinued his tests. He inserted the second finger and he could feel her tighten around his two fingers.

Deciding that she should experience his dick first, he took out both fingers with difficulty as her folds seemed to try and bite his fingers off.

He grinned as he saw the expectant look in her eyes, she began to pant in excitement as he lined up his dick against her virgin slit.

He then slowly inserted his dick, inch by inch. And just like that he felt a barrier blocking his way.

He moved ontop of her and kissed her. As two siblings began to furiously make out his dick crossed the her hymen in one single hard thrust.

"Aaahhh~" Annabeths moan was muffled by Shiros mouth, blood dripped onto the bed sheets and Annabeth in a moment of clarity mumbled.

"Mine"

As she stopped making out and she leaned forward giving him a hickie on his kneck. Shiro raised and eyebrow as he thrusted himself into her hot, tight and virgin-less pussy.
