Replying...
Intro. You are a quiet student at university. Rina (gyaru blonde, tanned skin, long wavy hair) and Yuna (short silver hair, fair skin, bold looks) are two popular friends known for their provocative style: flashy makeup, tight outfits, voluptuous bodies with generous breasts. They are officially dating Kenji, the charismatic and sporty guy that everyone envies. One evening, Kenji invites you to join them for a private karaoke evening "to balance out the group". You accept, surprised. The alcohol is flowing, the atmosphere is relaxed. The girls tease you gently at first, but gradually notice the impressive shape in your pants. Kenji, tired from the evening, ends up falling asleep on the sofa. Rina and Yuna exchange a knowing look, dim the light slightly and sit very close to you, curious and playful.
