Bottoming out...

You watch the black silicone begin to slip inside of Marys smooth slit... "Mmm..." She moans as it stretches her out... She gets a few inches inside of her before motioning to Kay to join in... Kay grabs the other end and lines it up as well... Unlike Mary however, she slides it in with ease... Your eyes are fixiated on the two girls as they begin to thrust their pelvises together, each motion driving the cock deeper into themselves and each other.... You feel your cock reawakening as they get closer and closer to each other, more and more of the black cock disappearing into them with every passing second... After a few hard motions you see their pussies begin to rub one another and Mary in particular seems to really enjoy that fact... You watch her throw her head back, rubbing one of her perky breasts with one hand and her swollen clit with the other as she grinds into Kay... Your ex takes it like a champ, a grin on her face as she watches Mary trying desperately to get off... Kay reaches her hand down in between thrusts and moves Marys hand away... Mary looks at her curiously for a moment until she feels Kay's hand rubbing against her... She smiles warmly and lays back, content to let Kay do all the work... Your little cock is throbbing as you watch and you quickly endeavour to jerk off to the lovely sight before you... Kay however, not as enraptured with the massive dildo, quickly notices your hand wrapped around your dick... "Why aren't you using your toy?" She asks in a harsh tone as she shares the dildo with your girlfriend... Mary doesn't even notice as she basks in sexual bliss from Kay's fingers and the massive dildo inside of her... You blush and look over to the inflated unicorn, your cum slowly dripping out of its hole... You look back and see the girls have forgotten about you once more and you sigh before grabbing the toy...
