Alex and Lucy

I heard them moaning before I even reached the kitchen. I entered the room and saw Alex standing behind my sister as he bent her over the kitchen table and fucked her. They didn't notice me at first but eventually Lucy saw watching from the doorway.

"Morning sis" Lucy moaned "enjoying the show?"

"I guess" I replied "but I never really liked being a spectator when I could be a player"

I walked across the room and stood behind Alex. I wrapped my arms around him and pressed my naked body against his. I moved my hips in unison with his as he ravished my sister. I felt Alex's thrusts become more frantic and soon him and my sister cried out as theirs orgasms rolled over them.

I took a step back from them as Alex collapsed on top of Lucy. I took a seat at the table as I watched them come down from their sexual high.

"You might want to clean yourselves up" I said "unless you want to show up to school smelling like sex"
