You

You try and avoid the incoming spray but its too late, your eyes managing to close before they get hit you feel the sticky substance land all over you. Your face sensing the deep load you received and your tongue able to feel the thickness and saltiness without even needing to move.

You swear you here your sister shouting something but your body feels really good and your brain is super fuzzy. Your tongue laps around for even more of it and as you swallow the thick load tastes surprisingly good~. Like super good~. You think you just had a orgasm from the oral taste alone but your mind is still wrapping around the sweet cum you had to know more about you didn't know about the potential situation down there.

Your mind does pick up on the shout of your name as you look to see your sister. How long were you standing there thinking about cum, did she see you swallow like the true slut you are, how come if she did you don't feel too worried about that potential judgement.... "Jack! Come on we need to go" .... "yeah... yeah... cum..." you say in blissful exhaustion but your sister seems to take it as shock as she grabs your hand.

"I'll get you back home, fuck whatever moms doing everythings or well everyones fucking" she said clearly confused by events happening but keeping calm... you didn't mind though all that meant was you could lick up more of that sweet cum as she looked around. "We'll go to the toilets nearby and get you cleaned up"
