Sports betting.

We all settled in to watch the game. Jess and the guys were all Green Bay fans. I was kind of a black sheep, being from Minnesota. Jane rooted for the Vikings for me, but she really just liked football players. The guys monopolized the couch, while Jessica lounged on her stomach on the floor with some pillows. She didn't seem to care that she was showing everyone her ass and pussy. Jane even seemed to enjoy looking, if the wetness in my crotch from her pussy was any indication. She was never this wet, she must have been really horny between showing herself off for all my friends and my hard cock poking her.
After the first few possessions, Jason called out to me. "John, why don't we make things interesting?"
"Oh?" I responded. Jane chuckled, as if she knew what was going to happen.
"If the Pack score next, Jane's gotta sit on my lap until halftime."
"I don't know man." I replied. "What do I get I the Vikings score?"
"I'll give you a private lapdance at halftime!" Jess piped up.
"I don't know if Jane would be okay-"
"You're on!" my girlfriend shouted over me. "It's just fun, baby." She gave me a sloppy wet kiss.
"Hold on, that's not really an even bet..." Alex said. "If we win, she's got to wear the Green Bay jersey so we can take pictures."
"Wait, what am I supposed to wear then?" Jess squawked in protest. Jason answered by stripping off his Iron Maiden shirt and tossing it to her. "There." He was a well toned guy: he had played football himself in highschool, a linebacker.
"Do we have a wager, baby?" Jane kissed me passionately, almost ravenously. She twerked against my cock and was surely showing off her ass and dripping pussy to the whole room.
"Sure!" I had faith in my team. I was about to get a girlfriend sanctioned lapdance from a smoking hot redhead. "But if there's no score by halftime, bet's off."
