[F/F] + [F/F/M] Surprise Threesome on a Tuesday

I’ve enjoyed a this subreddit for a couple months and finally have something to add. Skip down for the sex parts, otherwise I’ve always really enjoyed the set up as much as the sex itself.

I’m (Dave) a 24 year old guy, white, still retaining some of my physical fitness from college but definitely have more fat and less muscle. I’ve been dating Margot for about three years, we met in college and have been living together in the college town for a while until we can find solid careers.
