Sarah didn't even notice that Mason came inside her

"Oh did you cum, Mason?" Sarah asks, "you should have told me." Mason's heart sinks hearing this. His cock goes limp instantly.

"Do you want to fuck me again, John? Sarah asks, clearly hoping the answer would be yes.

"Sure thing, slut, but you're gonna have to wash your cunt really good. I'm not into sloppy seconds," you respond.

"Of course!" Sarah says to Mason's humiliation.

After Sarah scrubs her cunt clean you do indeed fuck her again - and for an even longer time. You fuck her in a few different positions on her and Mason's bed. Mason tried to join in by getting his dick sucked but he can't get hard again.

In the end you have Sarah pinned down on the bed with one hand lightly squeezing her throat. You keep telling her what a nasty slut she is as she begs you to cum all over her face. Sarah cums a few times during this fuck session. Mason watches from a few feet away, sitting on the edge of the bed confused by his man feelings about what he's watching.

When you cum you pull out and shower Sarah's face with your cum. It's not a big of a load as the one you pumped into her pussy, but it's still a larger load than Mason has ever even dreamed of being able to muster. Sarah laughs and smiles as you glaze her face and tongue with your cum.

"I should probably get home to Emma," you say after you finish on your best friend's wife's face. You leave them in that state - with your cum dripping down Sarah's face and Mason sitting on the edge of the bed not knowing what to say.

"Do you want me to shower?" Sarah finally asks. Mason looks over and takes in the full mess you've made on his wife's face. If this were a porn video he'd be cumming at the sight of a pretty girl like Sarah, but she's his wife... He doesn't know what to feel. There's no denying how sexy and hot she is covered in cum. But is the spice they were missing in their sex life? He's not sure.

"Yeah, I think that'd be best," Mason finally says.

"Ok honey," Sarah says. "Thank you for this." Then she kisses her husband's cheek. He can feel the moistness on his cheek and he knows that part of that sensation was your cum on Sarah's face and lips pressing against his skin.

Finally when Sarah is in the shower Mason gets hard and jerks off thinking about you stretching and fucking his wife.
