My girlfriend, Tonya and I lived with her parents when we went to college. Her mother, mistress Julie was a skilled dominatrix and demanded that any boyfriend of her daughter must learn how to suck cock and take it up the ass. The 70s were the days pre-strap on and guys had to have sex the old fashion way, sucking a real cock and taking a real cock up the ass. Mistress Julie took over that task bringing in her favorite boys, giving me cocksucking lessons and having studs fuck my ass while she held me down. I choked during ejaculations at first but soon I got good at sucking and swallowing. The guys were definitely hung and the fucking was painful, but soon I got used to annal penetration and I actually enjoyed getting fucked in the ass. Find me when I no longer hesitated having sex with a guy. Mr. Julie began teaching me to be a top and start having guys suck my cock and fucking them in the ass.
