[MF] Having a volleyball girlfriend

[MF] I have to admit. I get very horny by the fact that my girlfriend is a volleyball player and wear her uniform everywhere. Sex before/after her practice its one of the best things to do especially when she is dressed as a player (tight shirt/spandex short). The downside is that we end up messing some uniforms.
Sometimes she wants me to use her uniform too and I have to admit it is so much good.
Is that normal? We have the same fetish and its awesome.
Does anyone have this similar situation?
