Tim stopped dead in his tracks. His mind was racing. He started walking toward his room again and without thinking he walked in. What he saw amazed, disgusted, and bewildered, and aroused him all at the same time. "What the fuck are u two doing" was all he could say "suprise Tim" his siter and mom said together They got off his bed and walked over to him and unzipped his pants to reveal a seven and half inch dick. His mother reached down and started to play with his dick while his sister licked his sack. They pushed him onto the bed and argued over who got him first. His sister positioned his cock to her tight hole. She sat down which got a moan out of Tim. She started slow but quickend as she whent. Sliding up and down on his cock while rocking back and fourth. Tim was in so much pleasure he forgot how wrong it was to be doing this. Sense his sister had won the argument over who got him first his mom started fingering her self first with one finger then two then three. While fingering herself she started to pinch her nipple.
