@nprofile1q... (Just some friendly advice that I have also received before myself, from the girl my banner image was based on) Try to assume her position for a bit, see how that works. ;-)

And also imagine what part could, or would be in that position, for penetration.
(Pretty sure he's up against her tailbone there.)

HOWEVER, despite all that, yes, BEST season of all! Certainly beats the "I can't even move, due to heat."-season!!
Although, both of those seasons get sweaty!
Love your story/ies!
