The only experience I've had was with my ex-girlfriend on Halloween. We were both sophomores in high school. My parents were out partying at their friends house and I had my girlfriend come over to trick or treat. We had the house alone and things got frisky. At the time I was really insecure about my skinny body so I kept my shirt on while she got naked. She attempted to give me a blowjob but she only used her lips and not her tongue. It was really freakin weird but I didn't want to say anything because I thought I would make her feel bad. It wasn't very enjoyable and decided I would try to return the favor to her. As I spread her legs open and slowly moved my face towards her jungle, I took a little whiff and I think I teared up a little. I knew vagina would smell but this was awful. It was like a mixture of piss, sweat, and that nasty body odor similar to when a person doesn't wear deo. Like a nasty chicken smell. Anyways I thought that maybe that's just how vagina smelled and stuck my tongue out and hoped for the best. As soon as my tongue touched her I puked a little in my mouth but went on for like 3 more seconds before I heard a noise outside and pretended like I thought I heard my parents opening the garage. I quickly jolted to my door and tried to act like I thought my parents just came home and quickly ran to their bathroom on the other side of the house to wash my mouth and face. Also, I have no idea why but when I got in the bathroom and looked in the mirror there was a grey-colored smudge on my cheek that was kinda difficult to get off. I still have no idea what that was. The rest of the night was pretty awkward. We went trick or treating but she was silent the entire time.
