My name is Megan and I am 18, I want to know if it is wrong that my step brother and I are having sex. It started a few months ago when my bf went out of town for a few weeks during the summer and my step brother Trip was having a problem with his gf, so Trip and I started spending time together and confiding in each other, we became attracted to each other and we had sex, we have sex every opportunity we got, when our parents left the house and we were alone, and sneak into our rooms at night, sex in the shower when our parents left on a trip for two weeks, all Trip and I did was have sex and we stayed naked for those two weeks, when our parents and my bf Todd came back and Trip patched things up with his gf, him and I agreed our relationship would end and go back to being step siblings, but it hasn't been the case, Trip and I are still sleeping together, and sneaking around.
