Tell Heather to take off her bra and lift her shirt

As the two of you make out, Heather turns to face you, pushing her tits out in the oversized t-shirt she is wearing. “Come on baby... Lift your shirt up and show me those big tits of yours,” you say, trying to coax her into a show.

With a practiced hand, Heather shoves one of her hands through the sleeve of her shirt and begins to works some magic, moments later pulling the removed bra out of the sleeve. Once she stuffs the bra into her backpack, she hunkers down in the seat, completely out of sight from the bus driver. With a teasing grin on her face, she very slowly lifts the shirt and reveals her skin inch by inch till her breasts are out in all of their glory and the shirt is crumpled in a bunch just above them. Heather then guides your head into her lap as if you were an infant she was getting ready to nurse. “Mmm, come here, baby,” she coos seductively.

You lay your head in her lap and kiss her belly button, licking and gently biting the edges of her navel before licking and kissing all over her exposed midriff, earning a few horny moans from your teenaged girlfriend. Eventually you work your way up to her breasts and lavish them with affection, sucking and gnawing at both her nipples and kissing between her tits. Abruptly she stops and sits you back straight in your seat next to her before wrestling your cock free of your shorts. “Ah hang on babe… I got a treat for you, if there is enough room.”

With that she moves into the floor between your legs and gives your cock a few good licks to wet it down with her mouth lube. Then rising up slightly she grabs your cock around the shaft and slaps it against her nipple before thrusting her chest out and planting your cock between her tits, bouncing up and down. Heather keeps a hold of her globes and keeps them pressed against your shaft while you run one hand through her hair and trace her lips with a finger, which she licks and then takes into her mouth, sucking it like a cock.

The sight of Heather’s slutty actions is making it difficult for you to hold back your orgasm and your cock spasms between her boobs. Heather, sensing this, slows her pace a bit. “You want to come over to my house with me for a while? Mom won’t be home for a few hours and we'll have the house to ourselves.” As if trying to give you some incentive, she picks her pace up and before you can answer her question you climax.
