Lisa donned the strap on and grabbed a bottle of lube from the same drawer. Laura got down on her hands and knees on the carpeted floor of the bedroom. She looked to Anton who nodded, indicating the location would work for filming.

Lisa positioned herself behind her twin, and between her legs. She fondled Laura's pussy and clit, finding the area well-lubricated naturally. She put the head of the dildo at Laura's opening and pushed it in slowly. When Laura felt Lisa's thighs on her ass cheeks she knew she was in as far as possible.

Lisa began stroking in and out of Laura's pussy. She put her left hand on her sister's ass cheek, and slid her thumb into her pussy alongside the dildo. Toy and thumb pumped in and out several more times then Lisa pulled her thumb out and placed it on her back door opening.

"Ohhhh," Laura said, inhaling deeply.

Lisa rammed her thumb into her twin's ass bringing for a loud "Fuck!" Next she reached around her hip and used her other hand to rub her clit. All the time she continued fucking Laura with the dildo. All this activity quickly brought Laura to the edge, and Lisa started pumping even faster until she heard "YESSSS! I'm cumming!"

Lisa still didn't let up, continuing her three-pronged assault of her sister until Laura shouted "Stop!" and collapsed on the floor, pulling herself off both the toy and the thumb.

Lisa began massaging Laura's back and shoulders then migrated down to do her ass cheeks. When Laura's breathing returned to almost normal she began purring her satisfaction at the massage Lisa was giving her. When Lisa sensed Laura was very relaxed she surprised her by squirting lube on her ass crack and slipping the dildo into her ass.

"Ohhh! Damn, sis, that was sneaky," Laura complained while remaining flat on the floor. Lisa ignored her comments and began pushing the toy into her ass, each stroke slightly deeper than the last until she was fully inside the rear entrance.

Laura was lying on the floor, eyes closed, fists clenched, oblivious to everything and everyone except the fucking her ass was getting. She imagined the dildo was a real cock, attached to some faceless man she had decided to give her ass to. She reached beneath her hips and started jilling her clit in a slow, circular motion.

The double dildo Lisa was wearing was rubbing her clit with every stroke and the vibrator built into it was rushing her toward the goalposts. "Laura, I'm going to cum very soon," she cautioned.

"Makes two of us, sis. In fact, FUCK!" As her orgasm exploded from deep inside her pussy out to her entire body, Laura bucked back against her sister, driving the dildo in and out of her throbbing ass. Her gyrations were causing the vibrator end of the dildo to dance wildly around Lisa's clit and pussy, even knocking into her G-spot. Lisa came hard just as Laura ran out of steam and went limp.

Lisa pulled the dildo out of her sister's ass and collapsed on her back next to her twin. Anton grinned at the sight of a beautiful young woman with great breasts and a seven inch bright pink cock standing erect from between her thighs. He watched, and filmed, as Lisa slid her hand inside the strap on, obviously turning off the vibrator still inside her as the faint humming noise ended.

"Mmmmfffm!" they heard from across the room. Sitting up, Laura and Lisa followed Anton's eyes to see Mark and Matt sucking each other's cocks in a 69. Matt had just cum and Mark returned the favor mere moments later. They broke apart and sat up, noticing their audience.

"Sorry," Matt said. "You just made us super horny. We couldn't resist."

Anton laughed, saying "No problem but when we get back to your place y'all owe me some cumming."

"I think we can manage that," Mark replied. "Ladies, just for research purposes, do you both take it in the ass?"

"We've both taken the dildo, but we haven't found a guy we trust enough to let him cornhole us. We've heard too many horror stories from gals who had some guy just ram it right in with no buildup, often without lube as well."

"Matt and I both like being top and bottom so we try to alternate evenly. No reason why you can't do the same with your strap on."

"Yeah, but a dildo has no feeling, so only the one being fucked feels anything. You guys get to experience both positions fully," Lisa said.

"True, but then again we have no idea what a pussy feels like. I know I sometimes wonder, but since pussies are attached to women and I'm not into them, I'll never know," Matt said.

"Well, if one or both of us ever has anal sex with a guy, we'll ask him how it differs from pussy sex, for the guy. Then we can tell you what you're missing!" Laura grinned.

Mark, Matt, and Anton got dressed and left to return to the twins' apartment. As soon as they arrived they stripped down again and had Anton get on all fours on the floor. Matt laid on his back between Anton's legs and took his cock in his mouth. Mark lubed Anton's ass and mounted him from behind.

Matt synchronized his blowjob with Mark's anal fucking, taking as much of Anton's cock as he could each time Mark thrust into his ass. As Mark withdrew from the back door Matt pulled nearly all the way off Anton's cock, keeping just the head between his lips. He twirled his tongue around the ridge and poked the tip into his urethra.

Anton, already highly aroused from all the action he filmed earlier, moaned loudly, breathing deep. He knew he wouldn't last long but tried to hold back to enjoy the dual sensations as long as he could. Ten minutes in he called out "I'm going to cum soon!"

Mark started pounding Anton's ass as fast and hard as he could, hoping to catch up and cum when Anton did. Matt just continued sucking cock, waiting to feel Anton shoot off in his mouth. "Now!"Anton called out as he started flooding Matt's mouth with his cum. Matt swallowed as fast as he could but much of Anton's load leaked out and ran down his chin.

Mark kept stroking and brought himself over the edge, shooting his cum into Anton's ass until he had emptied his balls of his second load of the day. Spent, he collapsed onto Anton's back, his cock still buried inside his friend. Anton clenched and unclenched his sphincter, squeezing Mark's cock until it softened, shrank, and popped out.

When Mark got up from behind him, Anton backed up and laid between Matt's legs. Anton gave Matt's cock the same sort of attention Matt had just given him, and kept at it until Matt shot off into his mouth.

For the balance of their senior year the two sets of twins got together about once a month for video sessions. Naturally Anton was part of these events that resulted in a small, but hot, collection of videos for the women. "When we're old and gray we'll be able to watch these and remember what it was like to be young and sexy," Lisa once said.

After graduation Mark and Matt got jobs on the East coast while Lisa and Laura found positions in the Pacific Northwest. Anton was hired by a Texas company and so the five went their separate ways.
