Family Ties/Play along with Heather and pretend to be asleep.
Before you even have a chance to react the bedroom door is opened and a shaft of light invades the room. “Heather sweetie...” Your dad’s voice whispers from the doorway. Holy fuck it’s dad! You scream out in your head, scared out of your mind to know what would happen if he knew just how close his oldest daughter’s hand was to your hard, naked cock right now.
“Daddy...” Heather responses in her best, just-woke-up voice.
“Sweetie, what is Timmy doing in your bed?” Your dad asks with a certain unknown quality to his voice, one you can’t really place.
Heather clears her throat as if talking so quickly after waking up is giving her difficulty. “Timmy had the fire dream again.” Your sister explained. That was the perfect choice to be sure. 4 years ago you were caught in a shed fire that nearly ended your life. As you were ready to pass out from all the smoke your mother manages to break a window and pull out just in the nick of time. To say that it scared the hell out of you would be putting it mildly. For the two weeks that followed the fire you were unable to sleep without someone right next to you. That someone ended up either being your mother or Heather. It may be the root reason why you are so attracted both of them. When sleeping in your bed those two weeks, neither of them concerned themselves with wearing very much and you spent each night pressed against their near naked bodies. “With us having to be up so early I figured just let him get some sleep, so I pulled him into bed with me. Is there something wrong?”
Your dad grunts at some one out in the hallway, confirming that he is not alone out there. “No sweetheart, you go on back to sleep. I’ll you in the morning.” Your dad finally says before turning his attention to those in the hallway as he shuts the door. “You need to take him back to his room and have a talk with him.., I’m about tired of this bullshit.” You can hear your dad say through the door, but Heather grabs your attention by slipping her hand down from your hip and grabbing your cock.
“Mmm, you did really good Timmy.” Heather whispers as she lies down beside you and pulls you into her body. ”We’ll give it a couple of minutes so everyone is back in their rooms and then I am going to fuck your adorable little body till we both pass out.” She then starts to gently kiss your neck and jerk your cock, wanting to you on the edge till she is ready to claim your virginity.
