My girlfriend’s sister and I had sex at an hotel a few days ago, we both decided we were going to hangout and listen to some music since we both have similar music taste, she suggested we don’t let her sister know. She came and we hugged each other as soon as she came in, I held her waist and she basically melted into me, we stayed that way for sometime until I let go. What followed was a very intimate cuddle session with music, then we started to make out, trailed kisses from her lips to her thighs and pulled her panties off, and we did the deed. After we both agreed it was wrong and decided not to do it again, so we resumed texting normally like nothing happened but yesterday she texted me saying she wanted to meet up again, I am yet to respond to the message. I love my girlfriend and the guilt is eating me up already, but I can’t resist. I’m fighting hard against the temptation, we fucked so hard and it keeps playing back in my head over and over again. Especially how she holds onto me when I’m going hard. I think I’m going to block her
