My dick slid in one mouth then the other. My sister and her friend turning it into a sexual game, each one going deeper and deeper during their turn. Finally Siobhan had my entire length in her throat as Cindy brought a cigarette to her mouth, spit running down her jaw, as our eyes met and she exhaled right at me. I was in heaven.
"I'm gonna fuck him." Siobhan told her friend.
Straddling my cock as I sat on the couch. Cindy stood behind Siobhan rubbing her tits and kissing her neck.
"Fuck your brother, fuck him hard." Cindy encouraged her.
Siobhan moaned louder and louder as she bottomed out on my cock. She began to cum and I could not hold back filling my sister's pussy with my seed. She rolled off of me spreading her legs allowing Cindy access to my cum dripping from her hole.
I could only sit and watch as Cindy cleaned my sister's creampie. Opening her mouth showing her creamy reward, before returning for more. They moved into a sixty nine until both girls came again.
They were both covered in sweat, spit, and cum but both looked beautiful. Lighting cigarettes and grabbing some drinks they cozied up next to me, one on each side.
"I guess I'm bi." Cindy chuckled.
"I guess your a whore." My sister replied.
"Yea, I can live with that." Cindy shot back as everyone laughed.
We all sat on the couch until the Absolut was gone and so to were the girls. I helped them stumble to Siobhan's bed, leaving a beautiful mass of naked teenage girls to sleep it off.
I took a shower before heading back to the living room to have a few beers, there was no way I was sleeping anytime soon. I settled in and watched some late night TV. A few beers in I was really feeling good when a knock at the door almost made me shit myself.
Glad I had thrown on a robe I made my way to the door. Opening it to the shock of my life Cindy's Mom.
"Hey I'm Angie, is Cindy here?" She asked.
Scared to death I could only stutter "I think so."
