[IKSM pasta] Boy with a bigger dick than mine

A cocky young boy wins a size comparison against his rival and calls in a promise from earlier — and Daiki learns the price of losing. Bound to a chair and gagged, he can only watch in tears as the smug winner claims his busty girlfriend, who quickly discovers the kid's oversized cock outclasses her boyfriend in every way. What begins as a taunt becomes a sweat-soaked, x-rayed breeding ending in a deep creampie and a passionate kiss — with the boy already planning to make her his regular sex friend.
