Aaron came over the next night, and Samantha was there to greet him. Aaron took one look at the busty blonde and groaned as his cock began to throb and swell in his pants. He openly stared at Samantha’s fake rack with an obscene bulge in his pants.

“Well, that didn’t take long,” Samantha giggled. “Do you think you’ll cum spontaneously, or jack off in your pants while we watch again tonight?”

“Ugh, that wouldn’t be super comfortable, especially if it happens early in my visit. However, I need to do something. I’m not sure how long I’ll be able to resist the urge to cum; especially since I can’t seem to stop staring at your jugs! And I’m reacting like this after jacking off at home about half a dozen times last night. I didn’t mean to, but I kept dreaming about your bare breasts, or how that one tit felt in my hand. I woke up hard as a brick and I just had to put my hand on my dick and stroke it. I really can’t put into words how good it felt each time I woke up that way. I kind of feel guilty about reacting like this to your new body, but I just can’t seem to help it. Several times last night, I felt warm cum flowing over my hand before I was even awake enough to realize I wasn’t dreaming about jacking off while I stared at your big, beautiful breasts, I was actually doing it.”

Mocking her guest’s plight, Samantha asked, “You can’t control your reactions? I’d have never noticed if you hadn’t said something! So what is your plan to avoid shooting another monster wad into your pants?”

“Can I come jack off in your room? Do you have some tissues in there? You don’t have to watch if you don’t want to, but if you want to watch, I won’t complain.”

“Oh I want to watch! It will be the first time I see a hard cock, and the first time I see one squirting. I mean for real; I saw yours squirt twice last night, but only through your pants.” Samantha whispered excitedly. “Hurry up, before my mother notices you’re here.”

Aaron eagerly followed the teen to her room and pulled the door nearly closed. Then he unsnapped his pants revealing a fully hard cock in his boxers. He sighed in pleasure as he pulled his hard, throbbing shaft out. Then he accepted tissues from Samantha with one hand as his other stroked his angry red rod. “I really wasn’t expecting this,” Aaron explained. “I mean, I knew I was going to like getting to see your big jugs in person again tonight Samantha. And I didn’t think I’d be able to take my eyes off your tits. I even expected to get hard after staring at them for a long enough period of time. I really didn’t expect to be uncontrollably hard and aching to cum mere seconds after walking in the door.”

“Wow, I can see a drop of fluid forming on the tip of your dick, Aaron. That’s so cool! Are you starting to cum already?”

As the blonde girl spoke excitedly about his cock, the veins in Aaron’s dick bulged, and several drops of clear precum dribbled onto the tissue. “Oh Samantha, that feels so good, but it’s just precum. It feels good, but it just makes me want to cum more. I need the relief of shooting a big load of real cum. It’s not going to take long!”

“Will this help?” Samantha asked. She leaned in Aaron’s direction, and rubbed her tits against his arm holding the tissues.

“Oh fuck yes!” Aaron hissed. “Thank you so much for letting me do this. It was so embarrassing last night when I couldn’t let go of your boob. I mean, I loved touching it, but even though I had just cum, I simply couldn’t control my need to feel you up until after I had cum a second time. I didn’t want to be out of control like that again tonight since your mother didn’t much care for that. Oh fuck I’m close!”

“I know the guys at school are going to be jacking off thinking about me just like you did, and don’t mind. In fact, I want to know exactly what my new boobs do to them. Do it Aaron! Blow your load so I can see what it’s really like when a guy cums hard for me!”

Aaron couldn’t resist that sort of command; and hearing that Samantha liked the effect her modified body had on men sent a thrill through him. His cock initially shot forth big white globs of cum into the tissue. Then as he continued to pump it, more and more cum flowed from the tip of his dick. It just didn’t fly through the air like the first shots did. Still, his dick kept pumping more and more white jizz out.

“Can’t ... stop ... cumming!” Aaron hissed to the teen watching him.

Samantha whispered back, “This is so cool!”

“I’m cumming more than the tissue can hold! Quick Samantha, catch the overflow before it drips onto something in your room.”

Samantha knelt down beside Aaron and held her hands under his throbbing cock. Thick white semen dropped down onto her waiting hands.

“Fuck! That was intense. I think I’m finally done.” Aaron squeezed his shaft, and even more cum oozed out onto the tissue, then down to the waiting hands of the teen kneeling next to him. When he saw Samantha kneeling in front of him, he pulled her hair back so he could get a better view of her rack and his cock throbbed. One large final glob of cum dripped from the tip. “Guess I wasn’t quite done, but I think that’s it, for now. If last night is any indication, your big fake boobs are going to make me cum a lot more than just this though.”
