Birthday sex 🎈

Princess • I've spent a lifetime running, and I always get away.
Okay so today is my birthday (YAY 😊) and my boyfriend and I have planned on having sex in his truck. His truck only have 2 seats and I was wondering if there's any good positions I can use for a cramped space? Also, have you all experienced birthday sex before? (I never have) and is it more special than regular?
