I (m27) was quite hungover this morning and my gf (f28) was wrecked as well. We got up late and decided to have some good old fashioned shower sex. We hopped in the shower and made out while we are rubbing eachothers body's, I made her cum and I couldn't wait any longer so I turned her around to fuck her. With a moan of pleasure from her, I enter her pussy and start pounding. "Right there, keep going" she moans out, as i try to let her cum again. With bend knees and both of my hands on her tits, i keep going until it slips out and my legs cramp out from dehydration. We kept making out and once I slightly recovered I told her I wanted to fuck her again. She eagerly gets in position and we go again. We keep fucking but then she gets a bloodrush to the head and had to stop. I was too dehydrated to cum, so I finished my shower and drank some water. She later admits that perhaps another reason I couldn't cum was because she sucked my dick until I came in my (drunken) sleep I didn't even notice and thought that was a shame but also quite hilarious. She double checked with me if I was okay with her doing that when I sleep and I told her I loved it but I wish I was awake to actually feel it. We laugh and give eachother a kiss before we go about the rest of our day. One our best showersex sessions and a hot confession makes for a great start of the day!
