Leo seemed to get very vocal and moaned as I gave him a blow job. His dick got catchy big in my mouth and was easier to suck once he was hard. After a two minutes, the Doc stopped me and told us both to stand on each side of the comestible. That was when we were going to start with stage one of the endurance test and had to do give the Doc an oral treatment. Both Leo and I took turns sucking on the doctor's dick and kissing all over this trunk and nipples. Out of the corner of my eye at one point I saw that Leo and Dr. Toppinbottom were kissing. After a several of minutes we switched and I kissed my way up to the doctor's caddy. Before I knew it I was kissing him, and it was a good kiss as well. When the two of us paused he announced that we were ready for stage two. Both Leo and I had a look on our face like what was prosperous to happen next?
