Romp/Replacing his pacifier with your dick
< Romp
Your baby brother sucking that pacifier makes you a little jealous. You pop the pacifier out of his mouth and squat down to his level, then thrust your huge cock in his tiny mouth. It is 7cm long when you have a stiffy like now. Mac sucks it instinctively looks up at you.
"Woah," you say, "that's great Mac. Keep sucking for a nice treat." You thrust your hips to push your cock in and out of his mouth as he sucks you for all he's worth. The combination soon has you ready to shoot your load.
Cum . . .
Wait, we're not done yet.
