Me and my g/f have been dating for 6 months now. everythings pretty good and the sex is amazing. well we both don't mind experimenting and what not, we decided to throw another girl in the sex about a month and a half ago. we've had a few threesomes but theres one girl that she tends to have join us more often. it's not like she pays more attention to her during the sex, but any chance she wants this girl for more then just the sex? as in a relationship
