I personally love doubles and hopefully one day i will work my way up to a foursome lol. Nothing is better than having two mouths alternating or one is sitting on your face while the other is sitting on your dick. The only real turnoff or hold up during these session are when you have to switch covers whe alternating between two women. I get you women want to be safe no matter how long you and your doubles partner have been working together. Is there a really big chance of one catching something if you two are on the same cover. Wouldnt be better just to wipe with alcohol and jump back in to the fun? Just asking..
