When Mother's Day rolled around, I had recruited 10 guys - Bill and John from the football team, Kirk from the hockey team, Guy and David from the wrestling team, Justin and Lee from my science lab, and my close friends Jim, Carl, and Sam. All of them were more than willing to fuck a hot single mom for her mother's day gift. A few of them wouldn't believe it, so I had to have Cass help me convince them. After her special brand of persuasion, none of them had a doubt. We took the trip back to our hometown the day before Mother's Day, and I had all the guys spend the night at my house. Cass and I told them that we would take her out to dinner that night and then bring her to a hotel for a surprise. The guys were to wait at the hotel until we showed up, and then come up to the room about twenty minutes later, after Cass and I had gotten Greta all set up (and after I had fucked her a little bit to get her ready).
The plan went off without a hitch. We took Greta out to the Olive Garden for dinner, and talked of nothing important. She was really hitting the wine, and by the time we were done with dessert, she was hammered. We took her to the hotel and told her what was going to happen in totally frank terms. She just smiled and let us tie her to the bed. We wrapped her hands and ankles to the posts with small silk scarves, but tied them tight enough so that she could only move a few centimeters in any direction, other than her head for easy cock sucking. I lifted her skirt to see that she was again wearing no panties, and her pussy was puffy, wet, and red - she was hungry for a good hard cock. I dropped my pants and started stroking my cock to get it just right for her always-tight pussy, but Cass intervened. She stepped in front of me and dropped her pants and panties to the floor, offering her ass to me while she bent over to eat out her mom's twat. Nothing got me hotter than a bit of anal while watching some lesbian action, so I eased my cock into her ass while she happily munched on her mother's fragrant, juicy cunt. Cass moaned in harmony with Greta as I pounded her ass hard, shoving her mouth into Greta's pussy. Greta was thrashing about - at least as much as her bonds would allow - as she squirted her cum into Cass' waiting mouth. I saw Cass eagerly swallowing her mom's juices, and it pushed me over the edge. I moaned and gave one last powerful thrust as I released my seed into her tight asshole. Cass squealed and started cumming as my hot jism filled her asshole, her juices dripping onto the floor. I pulled my cock out and admired Cass' hot, round ass as my cum leaked slowly out of it. She dropped to her knees and started cleaning my cock, and under her ministrations, I was hard again within minutes. I heard a soft knock on the hotel door.
"Coming, guys," I called as I blindfolded Greta. Boy, was she in for a good time. I answered the door with my cock still hard and exposed, but none of the guys paid any attention to me; instead their eyes were transfixed on Greta's hot, naked, bound body.
"Holy shit," Kirk said, "Is that her?"
"Yep," I said, watching and grinning as all then of them approached the bound sex goddess on the bed, waiting for them.
"Jesus Christ, she's fucking hot," exclaimed Guy.
"Look at those tits, what are they, 36D," David asked, in total awe.
"36E," I said, and they all gasped.
"Can we....can we start," Sam asked, looking at me for approval.
"Go ahead, guys, she's waiting for you. Feel how wet and hot her cunt is, you can tell she wants a good fucking, and she's not going anywhere until she gets it."
They needed no other encouragement. All ten of them stepped forwards and started roaming their hands all over her body, paying extra attention to her tits, pussy, and ass.
"Can we fuck her mouth, too," Carl asked, taking off his pants and boxers to reveal a six inch erection.
"She loves it in the mouth," Cass said before I could respond, "and she'll swallow every drop." She motioned for me to sit and I did. She climbed on top of me and inserted my half-erect cock into her cunt. As we sat there, we watched the erotic spectacle unfold. Carl was crouched over Greta's neck, his cock in her mouth, moaning as she gave him a blowjob he'd never forget. Guy had his thick black cock in her cunt, and Jim was underneath her, his cock in her hot asshole. Sam had poured some lube on her tits and was rubbing his cock on them, while Justin, Lee, Kirk, Bill, John, and David watched. All six of them were lightly stroking their cocks, waiting for their turn. Greta was moaning and thrashing about, obviously having multiple orgasms. She screamed in pleasure when Carl finally took his cock out and blew his load all over her face.
"More cock," she cried, "I need more cock!"
