Nasty and that was a very sore one and let hope it doesn't happen again as some ladies can get carried away and nip you at times even if they don't mean it....
As I had one Lady who was a virgin and I was 19 and her 18 years and she use to kiss...
But bite my lips and one night in the club she bit me and went to chat one of lads and he Said hey mate did some one hit you and my reply was walk in toilet door as couldn't tell the truth...
Sadly that short relationship only last 2 week's...
P.S Never got around to sex as did like her...
