i loooooove threesomes. i've only had one. it was me, my boyfriend, and our other friend who is a girl. i would love to do it again.. either kind.
Been in a couple since my better half is bi (mff). They are really fun as long as all people involved have no insecurities. During the last one, I ended up masturbating in front of their faces towards the end as they were making out. It was a great time. Getting a rise just remembering.
