We nosed the boat into the pier and, being a gentleman, I helped the women down to the deck. They were looking very sexy, sunglasses on, hair tied b...ck, both were wearing bikini's with sarongs tied around their waists. A second later we were on the move again. Krissy whispered in my ear saying that she was gushing wet thinking about the days planned activities. I took the hint, kissed her passionately and at the same time lifted her sarong, hooked a finger under the gusset of her bikini. I pounded away like this for about 10 minutes and I wanted something tighter and more abrasive so I pulled out my soaked cock out of her pussy and I put it at the tip of her anus, and slowly push myself into her drug-induced ass. It was tight and amazing as I fucked her watching her tits bounce through her T-shirt dress, and her face motionless, eyes closed head to the side cause she was in my drug coma. I was getting close to orgasm at this point and I didn’t really care, so I exploded my nut. She denied me and said, “you are crossing your limits” I politely and sweetly winked towards my mom and said “Please momma!”She agreed and I started putting my hand in her pussy through her panty. After few minutes, I removed her panties and started fingering her pussy. It was so wet, I didn’t needed any oil to massage her pussy. Then I removed my dick out and started massaging it with the oil till it got fully erected. As my dick grew, I was fingering my mom and she started moaning. I licked. "Hey pops! Howsit hangin'? Wow, that's one hot piece you've got there!"Richard blinked. Is that ... Duke? No!It was. Happily putting the shaft to Barbara, his own son. What's more, she acted delighted with the activity. Her eyes were clenched, pushing back on the sink to meet her son's prick. Hearing Duke's greeting, she looked up."Ooof, oh! Ah! Hey dear, glad you could join us. Ah! Yes, don't stop babe!"Not pausing for a second, she arched back, ass higher to take Duke's dick."Barbara! What--?.
