My girlfriend was away from home for three days during our cohabitation period. To make sure she didn't catch me cheating, her friend Elisa came over to check on her. Even though I knew adultery wasn't allowed, I couldn't help but be captivated by Elisa's voluptuous G-cup breasts. She made a surprising proposal: if we could resist temptation for two more days, she would let us have sex on the last day. Unable to say anything else, I reluctantly agreed. We spent those two days in a state of constant arousal, barely holding back orgasms. Finally, the big day arrived. Despite my best efforts, I couldn't hold back any longer; my semen kept flowing endlessly, and my erection showed no signs of subsiding. It didn't matter whether or not this counted as infidelity... all that mattered at that moment was the irresistible pair of G-cup tits right before my eyes. As for my girlfriend, I can only apologize.

同棲中の彼女が実家に3日間帰省。僕が浮気しないために様子を見にきた彼女の友達のエリサちゃん…浮気はダメだと分かっていてもエリサちゃんの豊満なGカップおっぱいに釘付けの僕…「今日と明日の二日間我慢出来たら、最後の日にエッチしてあげてもいいよ（ハート）」まさかの提案に「はい」としか言えない僕はされるがままにパイズリ寸止め地獄…。最終日のセックスを目指してひたすら射精我慢。最後の1日、爆発。出せども出せども枯れない精子、収まらない勃起。浮気かどうかなんて関係ない…今目の前のGカップおっぱいに僕は夢中。彼女へ…ごめんなさい…。
