So, so many but the biggest two are probably:
1) Being out in the woods blindfolded and bent over while three or four random guys line up and take turns fucking me, not knowing who they are because of the blindfold but knowing they are different because each cock feels different in me. When they are done they leave and I remove the blindfold and walk out of woods naked while their cum runs out of my stretched and swollen ass down my legs.
2) Watching my wife lay in bed while several guys fuck her until she can’t take any more. When they’re done I lay down and she straddles me with her wet and well fucked pussy hovering over my face as all that cum drips out of her all over my face.
