No

You do not dare to interrupt them. Becky, the love of your life is enjoying herself clearly, as is Chad. And as you notice that your hand started to pull on your cock, so are you. Your hand slides over your painfully hard cock, a single hand more than big enough for it. It throbs as you see Becky tremble in orgasmic bliss.

And then you are interuppted. Not by a person, no. By your own orgasm. As you see Becky cumming her brains out, long hair sticking to her sweaty body, you feel something sticky in the palm of your hand. You do your best to keep upright as the orgasm saps the strength of your legs.

Letting the door close, you pull your hand from your pants. Watery cum strings from it, the realisation that you've just cum to your partner getting fucked hitting you hard.

I'm pathetic

You know what they call your kind. Pathetic. Worthless. Not a real man.

A cuck.

In shame, you run back to your apartment, intent on cleaning yourself off.
