I want to persuade my new partner to have a four-some, same room sex, same bed. We started seeing each other two months ago and I’ve been fucking her a couple of times a week. I mentioned casually I liked a four-some, but she said she is a one-man woman. I know that she has had 4 men long-term before me, don’t know how many short-term. I don’t want to put her off me, so am cautious about asking more but I would like to watch her being fucked while I fuck the other woman. Any suggestions?
