Visiting my Step-Sister’s home on a Sunday afternoon, I noticed my Step-Nephew getting aroused as I uncrossed my legs. At first, I was a little shocked seeming my Husband was right next to me. Then, I thought why not help my Nephew blow his load while everyone was sitting nearby. Once I had him sit next to me I watched him jerk his cock as I bounced my big 34 GGs for him. He needed lubrication. I figured spit would be best. I slid my head under the table and sucked just the head. How sneaky to have my Nephews cock in my mouth while my a Husband watched sports. Ummmmm...
