I felt my cock harden as she pressed against me harder, pushing my down onto the couch. I was caressing her back as we continued to kiss passionately....The fireplace was crackling steadily it’s flames competing with the flames of our ardor. Fire pulled her mouth from mine and began to kiss my neck and chest, something a woman had never done to me before. She kissed her way down my chest. I had never had a woman do anything with my nipples, but it felt wonderful when Fire began to suck on them. I. We stood again in kitchen but this time I let my shirt flop around showing my cock as we talked ,it was so exciting I was wanting her to look at my cock more and more. she didn't disappoint me at all when I looked at her book she looked at my cock I was trying to keep from getting hard but was having a very hard time if it. After about 20 minutes of this I was wildly horny and offered to let her sit down which we did next to each other. I let my shirt fall away on both sides when I sat down. Her thoughts of her Mom and now her standing there had my 8” growing. I went in to see Sen while her daughter, Lynn, stayed at the door waiting for a few more of her friends to show up.It turned out that Sen’s son was with her ex for the weekend as Lynn had invited about 10 of her 16 and 17 year old girlfriends over. The party was going strong and I would take pics of Lynn and her friends. Vodka was being passed around and the girls were getting more and more raunchier trying to do each. How are you today? I wasn’t expecting you here was I?” I asked.“Not really. But then again I wasn’t expecting to be called in for the Animal class. I’d like you to be there after I get out of the class. Can you do that?” Sammy asked.I had a brief flashback to when I last tried to attend the class. But seeing the desperation in my sister’s eyes I said, “I’ll attend the class with you.”The teachers and students were surprised to see me walking through the door. But we explained I was just there.
