My daughter Kat is bisexual. So when I walked by her room, I heard heavy moaning, but I did not know if she was having sex with a male or a female.

I walked out onto the back deck, looking over the pool. I was thinking about taking an afternoon swim, so I couldn’t hear my daughter having sex.

I changed into my trunks and went back out onto the deck. There was a young brunette wearing an almost nothing orange swimsuit. She was gorgeous, but had hardly any tits.

“Hello, handsome. You must be Kat’s dad. I’m Marny. We have Chem together at Uni. Both of us just had tremendous orgasms from sixty-nining. Your daughter sure knows how to eat pussy. But I have other needs. I am craving a nice cock to fuck me. Can you help me out?” Marny said.

I walked up to Marny and pulled her suit completely off. Her pussy was bald, and she barely had bumps for tits. Her areolas were almost nonexistent with brown tiny nipples.

I pushed my shorts down and my semi-hard cock popped out. I sat Marny on the rail and spread her legs. Her nipples were stiff, sitting on her little mounds. I pinched both her nipples hard as my thick cock penetrated this tiny girl. Her eyes widened, and she let out a moan and a whimper. I pounded her tight pussy. She grunted with every thrust. “Yes, this is what I needed. A nice stiff cock fucking my whore pussy.” She screamed.

Her thighs and labia were turning red as my body slammed against her. Marny dug her nails into my back as her orgasm spread through her. I slowed my pace as I watched her face distort with ecstasy. She begged, “My pussy is too sore to continue. Let me finish you with my mouth.”

I pulled my super hard cock out of her. “I have a better idea,” I replied. I grabbed her skinny arm and spun her around. “Hold on to the bottom rail,” I ordered. She smiled at me and complied. I spread her feet apart and opened up her butt cheeks. She had a beautiful pink starfish. I licked her ass and stuck my tongue in her ass. Marny moaned and pushed her butt into my face. I wet her with my saliva. Marny jumped when she felt the tip of my cock push against her anus. She let out a shriek when I spread her sphincter with my thick cock. I was a couple of inches in and rested. Marny pushed back onto me and my cock easily slipped fully into her ass. Her smooth, tight colon felt wonderful around my cock.

I slowly pistoned in and out as I held tightly onto her hips. Marny was enjoying me filling up her ass. “Yes, yes. Pump that cock into my ass.” She moaned. She reached up and fingered her clit as I quickened the pace. I was getting close and so was Marny. My seed shot deep into her bowels as she screamed with another orgasm.

I gently pulled my softening cock out of her ass. My cum spilled out of her hole onto the deck. Marny gingerly stood up and jumped into the pool. I dove in right after her. She put her hands around my neck and kissed me. Our tongues danced in each other’s mouths as we hugged in the pool.

Marny climbed out of the pool and I watched her beautiful naked body walk into the house. I swam my ten miles before going back to bed.
