My parents divorced and now me and my older Sister live with Mom in a crappy 2 bedroom apt. Me and my Sister have to share a bedroom (sep. beds) I am 13 and she is 15, so this s****. On top of that I am going thru puberty and get erections all the time. Sometimes when I wake up at night with an erection, I get in bed with my Sister and rub against her for relief and to c** onto her body. I cannot get enough of her, but I know it is very wrong. So far she does not notice or say anything…
