Don't ()

"N-No" you stammer out turning to leave, "we can't do that" the image of her throbbing cock now seared into your mind.

Before you can make it to the door however you feel her dainty hands grabbing onto you "please brother, it hurts." She cries out. You try and pull away but she's surprisingly strong. Sure you're not the strongest man in the world but you know you should be able to over power a little girl, something's wrong.

She pulls you down and you feel your knees hit the floor as her sizeable member hits your lips. Your mind goes blank as you feel it press against you, the sweet scent filling your nose and overpowering your thoughts.

She starts rubbing her cock against your lips but you barely notice, your thoughts drowned out by a full throbbing in your mind, a need you can't put your tongue on. Before you know what's happening you reach down and feel your own needy cock tightening in your pants.

You snap back and pull yourself away, realizing you had almost started sucking your sister. You look up at her and notice a strange fire in them that wasn't there when you first walked in.

She looks you back in the eyes and grabs you're head "I'm sorry Doug I can't hold back anymore." She says monotonically. You fight back but again her strength still over powers you as she shoves her cock down your throat.

You gag and **** as she slams herself into you, her cock forcing the air out of you. she doesn't seem to notice your struggling as she rhythmically uses you, infact your struggling only seems to encourage her.

You feel a sweet salty liquid pouring down your throat but realize it's only precum, even then it's more than You've ever shot out. At that thought you feel your dick twitch unwillingly, why is this turning you on?

You hear slapping of meat and gurgling filling the room and recognize it as your throat being used as a fleshlight.

Your sister is picking up the pace now, her cock twitching and throbbing with ever thrust. "Oh god Doug I'm so close!" She screams, thrusting deeply into you.

You try and push away, kick, pull yourself off her but know it's no use she's stronger than you, the entire session until now proves it to you. You can't breath now, 12 inches of hot futa meat are down your throat dumping gallons of sweet nectar in you and there's nothing you can do about it.

After a solid 2 minutes she finally lets you go, still leaking cum from that monster between her legs. You cough and sputter and notice heaps of goo pouring out and realize just how full you feel now. You smell like her cum now, a strange sweet sweaty oder and realize your leaking pre yourself.
