As Val started to lower her stepson into her so-called cleavage, Josh could feel his boner start to throb. "Val, please..." Josh said as she continued to lower him into the abyss below without a second thought.  Soon enough, Josh had touched down, pleasure ran through him, just feeling the soft breast flesh from his stepmother on his penis made him jolt.  He was about waist level into her cleavage, unable to move from the sheer shock of the penetration from her boobage.  Josh looks up at his beautiful stepmother, while she looks down at him with a smile, soon enough, that face was covered up by her descending finger. "Val wait!" Josh had barely said before the giant finger shut him up, and then proceeded to push him down further into the two mountains of flesh that he so adored. The pleasure was unimaginable!  With Josh sliding down, his member had gotten the great sensation of rubbing against the breast fat of Val.  Eventually, her finger gave, and allowed Josh to start breathing again, now feeling the warmth around his body, it was hard to breathe, being pushed up against both of her titanic tits.  Only his head was free from the giant breasts that entombed him.  "You look like you're having fun, honey." She giggled. Without warning, she started pressing her breasts together.  Josh began to be pushed up and down, with her sweat all around his body, his penis started to slide up and down with the rhythmic presses Val was doing. But what Josh noticed is that with her pressing her boobs together, he started to slide further into her cleavage.  "Va-!" Was all he could say before plunging into the sea of what he so desired to touch.  While all of this was happening Val just started getting wet from the way she can just dominate her stepson with just her sweating breasts.  Josh was suffocating, all he could think was "Am I going to die in here?"  It was damp, dark and warm, Val was still pressing her breasts together rhythmically, no more than 10 seconds and Josh came, It was intense, with being constrained by her massive tits, "It was great!" Josh thought.  But eventually all good things must end, Val pulled Josh out of her cleavage and held him at her eye level.  "Did you have fun baby?" she said, "It was amazing!" Josh responded.  "Well if you like that, I'm pretty sure you'll like this much more." Val cooed as she set Josh down on the chair that she had been sitting in.  It was warm from when she was sitting in it, surprisingly it smelt good, like milk and honey.  "Oh Joshy!" she said down to Josh.  He cranked his neck upward towards where the noise was coming from.  His jaw dropped, staring at her ass, it was big before he had even been shrunk, but now they were the size of planets!  Val was swaying her tanned bubble butt back and forth, and with no effort at all, Josh could feel himself getting hard again.  "Honey, you seem to be in mommy's seat!" she teased "You have 10 seconds to move or else I'm just going to sit on you," she said standing straight up as she slapped her ass.
