Beautifully ruined.

For her cuckold to know and accept that she ruined his orgasm and only let his cum spatter on her knee while having seen her boyfriend deposit his semen inside her is a powerful expression of the lifestyle.

It’s worth noting that his penis is not the stereotype of what sort of penis is assumed to be a cuckold penis or a denied penis, but that actually adds to the value of this gift of submission; it’s a perfectly suitable sex organ, yet she denies it in favor of her boyfriend’s!
