You jerk off many times to the nude photos of Sophia while Emma spends the night with Zach

The big night comes and as promised you got a few tasteful nudes of Sophia to keep you company while your girlfriend spends the night with Zach.

You save jerking off to the photos until Emma is with Zach (and Sophia is out of town). While Zach repeatedly fucks your girlfriend you jerk off to the photos he took of his girlfriend - a couple with her permission, and a couple taken without. You know Sophia is a bit of a prude, so they're not the dirtiest nudes - no open pussy shot or anything, but still - you have no problem cumming many times.

You find it particularly exciting how Sophia was betrayed by her boyfriend - just you seeing these photos was a violation of Sophia and you found that violation very exciting. It dawned on you that Zach was perhaps thinking related thoughts as he fucked your girlfriend - that he got off on violating your relationship - poisoning your girlfriend with every load of sperm he injected into her. But, it was your fault that she was a slut, so you could live with it. And, if you hadn't turned your loving girlfriend into a slut you never would have gotten to see Sophia naked.

The next day when Emma comes home and tells you about her night with Zach you think that his dick must be as sore and raw as yours is. You both came a lot focusing on the other guy's girlfriend - the only difference is he had your girlfriend in the flesh while you just had some photos of his girl.
