I was regularly spanked for discipline by my then girlfriend´s stepmother. Long story short, I got my girlfriend in trouble, so her stepmom told me, if I wanted to keep dating her, she will be spanking me regularly, in private, when her husband wasn´t there, something my girlfriend told me she made with her, too.
I accepted, so she told me to remove all my clothes and bend over a sideboard. She noticed my erection, but didn´t say anything. Then she step by my side, put a hand on my waist and spanked me with the other one, stronger each time. I noticed by the mirror in the sideboard she was looking to my penis as expecting to go limp, which it didn´t. It went for a few weeks until she decided to speak out and tell me I wasn´t supossed to enjoy this, so we entered into a battle of wills where she tried different methods to break me:
- blinfolding me (so my skin was more sensible to the touch).
- using other implements such as a paddle and a belt.
- spanking my genitals with that implements, too.
- backlashing me with the belt.
- slapping me across the face.
- scratching my torso with her nails.
- bellypunching me.
- having me to take cold showers (aside from temperature, it´s supossed to make the strokes feel harder).
- having my girlfriend to watch my punishment (I was the top with my girlfriend on bed, so watching me in that subservient role was intended to shame me).
None of these methods resulted, aside from some moments where my erection went limp. The methods that really worked with me were:
- having me masturbate right before the spanking.
- spanking my genitals with the paddle right after cumming. That´s peculiarly painful. It even keeps you from masturbate for a while after the punishment.
- since I lasted quite to cum in order to delay my suffering, she had my girlfriend masturbating me frantically in front of her, and when I was cumming she told her to retire her hands and smacked my genitals with the paddle, giving me a ruined orgasm.
In my experience, the last one is the method that best removes the sexual component of the spanking, since the pain is excruciating.
I wish I had presenced the spankings of my girlfriend by her stepmother, but I could only hear them from time to time, when she was spanked prior to me.
My gf said sometimes, after being ordered to strip naked, her stepmother stripped herself to her underwear. I guess, aside from titillation, it had to do with the fact, as a middle aged woman, she had better body, despite my gf being in her early twenties, so it added an extra layer to the humilliation.
