So Many 'first' Got Me In Trouble And Now I'm Feeling Guilty.

My husband had cheated on me some 5 years ago and i have forgiven him and moved on. He is the only one that have ever come anywhere near my private area and no one else. My mother have taught me that only a husband should have sexual access to a wife's body as long as both are still together.
Now my husband went overseas a month ago for 2 weeks and i got really horny for some strange reason. I have never been this horny in my entire life. I am not so sure if it's because of the new underwear that i've decided to try but when my husband had left i bought a couple of 'thong' and my word!. These women garments are giving me literally a warm time but between my legs. I have never worn these types of underwear before but here i am. I felt sexy and horny at the same time while wearing them and on the first weekend being alone at home i started to burn with pure lust. I started drinking alcoholic wine regularly which did me no justice, and the more i did the more my vagina twitched with sexual thirst. I really wanted to stay away from having sex with someone else so i said a massage is fine even though i have never gotten one before.... But i thought at least it's not like having sex.

I found out where to go and off i went. Upon reaching there i got the impression that more persons would be at this location but not so. The gentleman who seem like a very young man who's age is still not known to me, only have space for a single client.
We proceeded to the massage room then he asked me what type of massage i preferred. Now i am lost as to the kind of massages he's introducing. I remember him saying 'sensual' can be fun and i said ok that can work, not knowing what that is.
I only realized the one i have chosen after being fully naked in front of a stranger.
Still feeling the effects from drinking the wine i did not hesitate to complied with all that he said and in 10 minutes or less i was caught in no man's land. His touches have me on edge ,my toes started to curled and my hands are now grabbing both sides of the sheet.
My tension dropped when i felt his finger in me. I then let myself go when he started licking my vagina where he spent much time on my clit.
By then i started grabbing onto him while raising my body to meet his face. He responded and licked me harder sending me to my first orgasm outside of my husband.

That young man then took out his cock and i told him no. But after he stuck his finger in once again and started working my vagina i grabbed on to his cock and told him; 'please do me good'! He sent his cock so far up my vagina causing me to start calling him by my husband's name. I felt really shame but he understood as i told him i have never had this kind of interaction with anyone else. I went there 3 days in a row and got the same treatment. I am now feeling guilty and slutty.
