Sex with my cousins girlfriend but now what [MF]

There was a family gathering two days ago and my cousin and his girlfriend came. The family gathering took place in my aunts house. My cousin and cousins girlfriend are 23, they have a three year old and I am 21, they just came to the states about a month ago and they have a three year old. While at the gathering my cousins girlfriend started talking to me and we actually talked for a awhile. She asked me questions about getting a job and how to make connections. I felt like I was getting interviewed with all these questions she was asking. Eventually she stared smiling and touching her hair more and playfully touching me.

Eventually it was dinner time and she immediately sat next to me. She kept asking me more questions about places to visit and if I could Introduce her to my friends because she doesn’t know anybody here. I was getting really annoyed because she wouldn’t let me talk and she just kept taking and talking. While we were eating she touched my thigh while I was drinking orange juice, I coughed a little and spilled some juice on my shirt. The table looked at me and said what was a wrong. I lied and said I choked on the juice. The table laughed and my aunt said, “I didn’t know the juice I made was that good.” I looked at my cousins girlfriend and she just giggled.

Anyways after the dinner everyone started dancing and drinking. My cousin was already drunk and my cousins girlfriend wasn’t. I also wasn’t drinking my either. Anyways my cousins girlfriend disappeared and I started talking to my aunt and parents and suddenly I get a text from my cousins girlfriend saying, “come upstairs”. My dad smirked and laughed and asked if it was my 2nd or 3rd girlfriend, I said it was just a friend and I excused myself to the bathroom. I went upstairs and I saw my cousins girlfriend peeking out a closet and I went inside. I asked if she really wants to do this? She just smiled and kissed me.

I closed the closet door and we started making out. We took our pants off only and she gave me oral for a few seconds. I searched my wallet and I didn’t bring a condom! I told her this and she said, “I like it raw anyway.” I asked if she was on birth control and she just got on top of me and said looked at me with a seductive look. I decided to risk it and she began to ride me for a two or three minutes, she wanted me to cum inside but I pulled out to stop the release in time. She got off me and she turned around and I put it back inside her for doggy, after a few minutes it felt so good I almost finished inside her, but I quickly pulled out and finished on her back. One of my family members called me and asked where I was. So we just put our pants on quickly and went out the closet one by one. The gathering ended at 3 or 4am, I can’t remember exactly.

Anyways like I said it’s been two days since this happened and now I am starting to feel so a little guilt. My cousin and I don’t talk often and we don’t really have a close relationship. My cousins girlfriend texted me saying if I could come over and wants to see me again and hang out.

Should I tell my cousin or keep it a secret?
