Maybe it was the stimulation of her G-spot. While fucking her pussy, I was looking at her winking brown asshole, which I had lubricated to a bubbling ...tate with my saliva, seemed to have dried. I couldn’t resist and in a fraction of a second, switched between Trish’s holes. I drilled my cock downwards into her asshole, which seemed insane, as the size ratio between the diameters seemed 1:100. Trish gave out a surprised cry, which was followed by many others in continuation, as I kept fucking. What are you doing?”I got infuriated by now but went down and again started to lick her there, and she got out due to a hangover. Then after licking for almost 10 minutes, I applied a condom and inserted my cock in her, and started to hump her.At first, she was not conscious. But as I started to hump her harder, she suddenly woke up and noticed that I was fucking her. She immediately shouted and got my cock off, and damn, she slapped me hard.I felt scared now. She shouted at me and said, “I. I’m hoping we can maybe get started earlier next Sunday, that is if you want more.”That brought a smile to his face and he nodded and gave her a kiss. She put on a robe and he put a towel around his waist and they went down to the shared bath and he had his first shower with another person. She noted that he was erect as she toweled him off and gave it a little more than a brief kiss. “That will be a treat for another time,” she thought with a smile.Their Sunday afternoons became something she. My cock was now so hard I thought I was going to blow my load right there.Then my mom took her shower and came out with just her bathrobe on. She had tied it around her middle but it was loose enough that that I could see her tits and her pussy and she didn’t even try to hide them when she went by. I wanted to reach in pants and relieve the pressure but I knew there would be cum everywhere in seconds if I did.I started to get up and go to my room but they started talking to me and I couldn’t.
