I've been out of town for work and came back but she was suppose to be at the preachers house with his wife, we proceeded to get frisky and noticed she was sweaty down there but they had been sitting outside for some time. She usually is somewhat dry when we start intercourse but it seemed a little lubed so was concerned, after the fact I checked her shorts and they were infactuation sweaty as well as the rest of her clothes, but a strong smell of semen was apparent, could it be in infection or infact she did have intercourse right before me?
