How much do you want that smacked bottom?

Enough to risk a lifelong friendship?

How you evaluate that risk is your call. I do believe that everyone has a right to sexual privacy, and your desires are no-one else’s business. But it’s also true that your friend is likely to be hurt if they perceive you and their partner consorting behind their back.

You could start talking about kink, sexuality and spanking with your friend. Make it clear what you’d like to experience – and encourage your friend to be candid about their desires too. Perhaps if a putative spanking arrangement involving the partner is not seen as threatening the relationship, it might work.

I know you mentioned your interest in in spanking, and not sexual intercourse, but it’s worth reading this recent article about the emotional complexities of threesomes. How sexual activity with 2 others is actually the most common sexual fantasy. Yet it few are ready for the real-world consequences beyond the imagined ideal. Tread carefully, respect others, and have fun.
