I caught up with her there and gave her a hug. That was priceless, I said, did you enjoy that? Mum just giggled, and pressed herself against me. We ...alked together along the prom, and it wasn't long before mum was pulling me into a bar for another drink. I sat on a stool at the counter, and got mum to straddle me, chest to chest. The younger of the two barmen came eagerly over to take our order, whilst the elder one looked less than pleased to see us. As mum had straddled me, her dress rode. Ummm... " Jennifer said, clearing her throat. "I thought I told you too to do the dishes?"The two on the sofa practically jumped apart; startled like a couple of pre-teens caught making out."Uh... we did," Jimmy said, his face flushed with excitement and embarrassment."Well, we have the birthday girl down the hall waiting for us. We shouldn't keep her waiting long," Jennifer said as she led them out of the living room. "Now, I don't want you to be too shocked when you see Shelly," she warned,. He wiped his hands off with a towel and then he lined up his cockhead and said “Here it comes my friend.” He started in nice and slow and then once his head popped in he positioned himself so that his hands were resting on the table right by my left and right rib cage just underneath my armpits. “Are you OK?” he said. My eyes were in the back of my head so I guess he was worried. I said “yes, just fuck me.” “YEAH, JUST FUCK HIM GARY” came the outcry from both sisters at once. So Gary fucked me. She pushed her beautiful tits right into Ann’s face. She shook them back and forth across Ann’s face until her harden nipple had found Ann’s mouth. Ann ended up sucking on both of Sarah’s nipples over the next few minutes.Sarah now straddled herself across Ann’s face. She lowered her beautiful pussy down towards Ann’s mouth. She moaned out, “Suck on it Ann! I want to feel your tongue sweeping across my clit!”It took Ann a few seconds but gradually she opened her mouth and began to taste Sarah’s.
