Go on then...

"Fine.." Jack says but you can tell he's quite excited at the prospect

Jack gets onto his knees in doggy style position over the top of Jennie, while giving her a quick kiss. While watching this you put your large strap on and get in position behind him.

"Ready Jennie?" you ask

"What about if I'm ready?" Jack retorts

"We know you can take whatever we throw at you Jack" Jennie says with a wink

Both you and Jennie line up your dildos with Jack's ass and together, push inside. He moans with a mix of pain and pleasure. You see his once tight ass slowly expanding to accommodate the large intrusions.

Once Jennie and yourselves' dildos are fully inside him you both start to pull out and push in. You get into a certain rhythm in which you are doing it at the exact same pace. One second Jack's ass has just the heads of the dildos inside and the next it's full to the brim with you and Jennie fake cocks.

You check to see how Jennie is doing and you see Jack's large cock slowly increase in size until it rests perfectly between Jennie's tits. She pushes them together for him so he gets to fuck her tits while you two destroy his little asshole.

You two pick up the pace, his ass being fucked relentlessly and his cock getting to fuck Jennie's breasts hard.
