And I am feeling so tired and sleepy and happy. What is that? Endorphins? Oxytocin? What? Haven't felt this relaxed in a loooong time. And the weird thing? I didn't have an orgasm! Didn't receive anything from him (he likes to be "served"), was not even fucked! I gave a lot of oral and was very serving for 1hr. Someone please explain it to me!! I feel great!
