I didn't have to spend too long floundering in Jenny's pubic hair before she grabbed me again. Still holding me about level with her crotch, she grinned and said "Now it's my turn to have some fun. Head or feet first?"
"Head or feet...?" If the answer is obvious to you, you obviously hadn't been shrunk, toyed with, licked, sucked on, and tossed around like I had. I think my brain had shorted out. I hesitated just long enough for Jenny to shrug and plunge me, head first, into her vagina.
How can I describe what it felt like? If being in Jenny's mouth was a full-body experience, this one was nothing short of mind-blowing. She would ram me deep into her, into a wet, warm place where I could feel the soft walls around me pulsing and squeezing me. I would stay in there until I was sure I was going to suffocate, then she would pull me back out for a breath before shoving me back in. I could hear her muffled moans even inside of her.
I must have orgasmed several times. Later on I would worry briefly whether or not Jenny was on the pill, but she probably is above such mundance concerns. The experience seemed to take forever, until I realize Jenny had let go of me. While I was inside. I started to squirm and panic when I realized that her walls were clamping down harder on me, and her cries were getting notably louder.
Then there was a spasm, and I shot out of Jenny as she climaxed. I was flung some distance to land on the sofa, exhausted, out of breath, and thoroughly soaked with Jenny's fluids. Jenny was looking at me from the other side, panting softly, legs spread lazily, an angelic smile on her face. "Now wasn't that fun, Leo?"
