My girlfriend went to Amsterdam with her lesbian lover, in the early 70’s, and they brought back strap on dildos for souvenirs. They locked me in their bedroom and strapped on their dildos telling me they’re going to give me a big surprise. Well, one lady fucked my mouth the other one fucked my ass, giving me an introduction of what it’s like to suck cock and take it up the ass at the same time. My girlfriend was actually quite skilled at fucking and even though it hurt at first, I actually got a huge erection and blasted my cum all over the sheets as you continued fucking my ass.
