He was two weeks from being nineteen. He was twenty years younger and I found him very horny and willing to learn. He was hung and loved sex. We did a...lot of kinky things and had several threesomes with another girl but I wanted one with a guy. I told him I was going to find the perfect guy to help me train him for male sex so we could all fuck. I looked on a bi-sexual site and hunted for the right man. He had to be attractive, hung(at least 9 inches) and thick. He needed to be a great tongue. He took his mouth away from her nipple and went to her mouth for a kiss. He kissed her on the lips but she did not respond. He moved back a few inches, “When I kiss you, you kiss me back.” When he saw no question he moved back for the kiss, this time she returned the kiss back. After several minutes of heavy, passionate kissing he pulled away. He looked at her naked body and knew he could not contain himself any longer. “Bend over and spread your legs.”This she did with out a word, using a seat. The black guy I was sucking this time was kinkier then the first as I heard him beg, "Use your teeth baby, use your teeth."I gently dragged my teeth up and down his shaft as I sucked and continued using my tongue on his cock. In no time, this guy was also cumming in my mouth. As he backed off from the hole, I slipped my hands down my slacks and into my panties and I began to eagerly rub my clit. Then a third black cock got shoved into the hole. As I started sucking on this cock, a wild idea. Um 13 Uhr war es dann Zeit für den Unterricht. Da der Ausbilder ein privates Problem hatte, war um 15 Uhr schon der Unterricht schon zu Ende für den ersten Tag. Ich schlug Kathrin vor, zusammen Laufen zu gehen und sie war einverstanden. Eine halbe Stunde später standen wir unten vor unserem Gebäude und war fertig zum Laufen. Kathrin hatte eine kurze schwarze enganliegende Hose und ein weißes T-Shirt an. Das T-Shirt lag nur etwas eng an. Darunter konnte ich gut noch ihre Sport BH sehen. Wir.
