We did this for the next few minutes while he slowed and sped up multiple times, and I grinded her mouth into me and then eased up. We were getting he... so close to an orgasm but I knew she needed to lay on her back to really have that orgasm she wanted. So I got up, pulled out a blanket I brought and laid it down for her. She immediately knew what I was going for. She got up out of the pool and laid down on her back. “Fuck me hard. I need it” she said as she started rubbing her pussy and clit. "We had a long talk with Mom and Dad most of the day Sunday." Liz said. We talked about, you know, that thing you are going to do" "What things?. If you want to talk about something then you need to talk to me as an adult." I said. "OK, have intercourse with us." Liz said. "Take our virginity." "Oh that thing." I came back. "That is off in the future. We have a lot to talk about before that." I said. After that, they looked a little disappointed. I told them all in good time. Sissy got her two. The hole wasn't at an ideal height for me, I had to spread my legs fairly wide to get to the right height and I still wasn't 100% certain that I wanted to trust a complete stranger with my favorite appendage. "Fuck it." I was really hard by this time and placed the tip of my cock on the rim of the circle. The fingers gently enveloped the head of my cock and lightly pulled me farther into the gloryhole. My pulse skyrocketed. Holy shit, is this actually happening? I felt the tip of a tongue. "I couldn't help but hear you and katie in here." Seeing the flesh colored panties in disarray on the floor Rich picked them up, bringing them to his face. Breathing in a deep breath, Rich let out a soft moan, smelling Katie's scent on them. "And from what I can tell your sister was already wet when she tried them on, I think your sister needs to be taught a lesson, what do You think, Hannah?" Rich asked with a deviant grin."Mmm...yes, I think she could use a lesson, couldn't you little sis?".
