Eventually she came down from this intense orgasm, released my head from her thighs, and sat up with physically drained look on her face. She was pant...ng, glassy eyed, out of breath, and smiling a big grin.“Ohmygod. Ohmygod. Ohmygod that was so intense, she mumbled over and over in a little girl voice. “Thank you.
