It drives you crazy!

"Oh fuck sis, that’s so hot... I can’t wait to cum inside you again… but I need you to cum with me." You moan softly.

Normally you have incredible stamina but the knowledge you are with your own sister seems to just overwhelm you. You are so focused on each other’s impending release you don’t hear the door creak open. You pressed your lips against hers and engage in a rough and passionate kiss, your tongue thrusting into her mouth as you continue to thrust your cock into her throbbing pussy.

Alexa archs her back as her body shivers with pleasure and cries out, "Oh fuckkkk..... Mmmm yeah fuck me harder John... harder!!!."

As your orgasm approaches and your thrusts became wilder and harder your sister cries out, "Oh gawwwd! That's it! Right there! Ooooo I’m gonna cum! Cum with me big brother!”

“Oh God Alexa! I’m gonna cum too!”

Alexa cried out, “Oh fuck yeah John! Cum inside meeee! I need it! Your little sister needs to feel your cum shoot deep into her tight pussy!"

“Oh ffuuckkkk I’m cumming!” you yelp as you thrust your cock deep inside her as she rides out her orgasm, Alexa can feel you shaking atop her as you rapidly approach your orgasm.

Gripping you tightly with her legs, her orgasm began to sweep through her body.

“Ohhh god Alleexxxaaaa!!! Take your brothers cum!!!” you groan as you shoot a huge load deep inside her. The feeling of her hot and wet pussy squeezing your cock intensifies the feeling and milks your seed into her. You can tell it drives your sister wild as you feel her shudder with pleasure when she feels your cock spilling your seed deep within her womb.

As you come down from your orgasms, you hear a gasp at the door...
