Mary gets hers...

You begin to slide your tongue up amd down her achingly horny slit... "Mmm..." She gasps above you as you meekly service her with your mouth... You see Kay watching intently from her side of the bed as you eat out your girlfriend... Kay's owm hands slip towards her sex as she watches her panty clad ex lick his new girlfriemds pussy in fromt of her...

"Good boy..." Mary says in a soft and demeaning tone, "Just like that!" Her voice raises at the end into whats almost a squeak... You work your tongue quickly, circling her clit, lapping at her pussy as she moans and shudders above you... You can tell she was close to losing the bet as she quickly approaches orgasm... You decide to try something new in an attempt to finish this quickly and get out of these panties...
