I saw kissmark near the right nipple of my wife

The night after having a reunion with her friends,we were on the bed ready to make love.

But i was wondering why,the reaction of my wife was quite different. For 12 years of marriage,it was the first time i noticed that my wife was covering something...or...i dunno.

Maybe she was just excited for sex. i want her to lay down to suck her nips but she wanted to sit up and grab my di** and suck it. Again i lay her down again but quickly she stood up and again sucked my di**.

It was,for me strange reaction...this is what happened the whole day:my wife asked my permission to hang out with her friens(batchmates in highschool)so i let her go.

It's fine because she's doing it many times before.so she went alone.i left alone at house.the whole day i was alone.@3pm,she came home.smiling,happy,and kissed me.that night we are having sex.but noticed some small bruise near her nipple.

I just ignored it.2 weeks ago i asked her about that because i knew it was a kissmark.

At first,she denied it.but eventually,she admitted she had sex with her former classmate.but she denied they had relationship.should i believe with her?sex without relationship?

please help.i'm confused...thanks
