I have been a bull to a number of couples, some in a hotwife relationship, others a cuckold relationship. I would estimate that about 80% of the woman want it raw. Which is why I get regularly tested.
You would be surprised how many women who take me raw do so without their husband knowing.
One gal I was fucking occasionally, up until COVID19, pretended to be modest and want to fuck under the sheets while her husband watched. She would make a big show of putting a condom on my cock, then once under the sheets slip it off.
