Hooking Up by Crystal Kaswell
It's supposed to be fun without strings, but resisting her is so damn hard. I’m good in bed and I know what I want. So when a curvy grad student catches my eye, I do what I do best. I take her home. I kiss her hard. I-- well, a gentleman doesn't kiss and tell. I don't expect to want more. But I do. Iris is smart, sweet, and innocent as hell. I need her as often as possible. We strike up an arrangement. There are three rules. All fun. No strings. No falling in love. But then I've never been very good at following rules.
