My friend accidentally saw my cock at a house party when I was changing in a bedroom and she came in to use the ensuite bathroom. It became an inside joke between us and nothing happened.
At Christmas time I got her for secret Santa, I gave her something boring as a gift for everyone to see. But later I saw her and gave her the cloned cock and a card telling her she could look longer, to keep the inside joke going.
I assumed she wouldn’t keep it but I found out recently that she still has it and has used it. Don’t think anything will happen between us but I still enjoyed it.
