Romp/Friend/Toddler Daughter2/Fuck/Cum
The sight and feeling of your dick inside the toddler's pussy is enough to get you off and your hips jerk, your balls clench and you shoot some of your boycum right into her tiny little cunt.
As soon as you finish, you pull out, wipe your dick on her diaper and then find a clean one to put on her. A few moments later, she is fast asleep just as when you first saw her.
