I had a friend whose gf was very vocal. she could be heard a block away, it was very embarrassing to him. I had the opportunity about a month after they broke up to bang her, and I did. she started "oooooooing" real loud right as I stuck my cock in her. I eventually cupped my hand over her mouth a little bit. I always thought it was an act, but she was consistent, always pretty loud, and she would get real horny. there were a few days when all I did was fuck her. we lasted about a month, everything was about her, and she didn't like hanging out with me in public. she just used me for sex, and being a horny young lad at the time, it wasn't all bad, just no future in it.
